THE SQL Server Blog Spot on the Web
You may disagree, but I believe it is a good practice to cluster all the SQL Server instances. That is, even when you plan to run a SQL Server instance on a single machine, you should install it in a single node cluster.
The primary advantage is that you only need a single standard SQL Server build instead of one for the stand alone and one for the clustered. This results in simplified configurations such as when you configure network aliases, Kerberos, and multiple instances.
If you need to add a second node later, that change will be totally transparent to your client. You may question how often one would need to add a second node. True, that may not happen very often. But when it does happen, you'd be thankful that you already have the cluster in place. Moreover, consider a DR scenario where you don't want to have a two-node cluster doing nothing just in case there is a disaster. If it turns out that you do need to run your production on DR for an extended time period, you probably want to protect your production with a cluster. In that case, adding another node would be painless if your DR is already a single-node cluster.
When it comes to using network aliases, I strongly prefer to expose and manage all the network aliases of my SQL Server instances explicitly as network resources. Network resources introduce additional constraints that make the network aliases less fragile to mistakes and help reduce chaos when we need to move them among the hosts.
Kerberos configurations can sometimes be finicky and the procedures for a clustered instance and those for a stand-alone instance are different. Anything you can do to reduce the Kerberos configuration complexity is a plus for robustness of your environment.
When multiple instances are configured in a cluster, they must have separate IP addresses, and this makes it trivially easy to create network aliases for a named instance, completely eliminating the need to reference any two-part name on any client and making the 'server location' completely transparent to all the clients. By 100% server location transparency, I mean the ability to move a SQL Server instance to a different machine or a different cluster without changing any configuration at all on the client side. This offers huge convenience, and in many cases is an absolute necessity.
From my personal experience, I have not seen any serious downside to this approach. Hope that's your experience as well. As always, I'd like to hear your different views/opinions on this.
I love this idea, and will think about doing it at my job. I've just got management convinced that the hardware costs for a second node are not all that much when you run Active / Passive for resilience. So now, I've got the approval that any new installs (save perhaps for unique instances like SCCM at a remote location) will be clustered. But I like your thinking, as it would make things much easier for me to go back with this approval and just build up and attach a second node.
It does assume that your storage model is sharable, if your server is using only internal disks then it's not something you can do, even with a DAS you may have some issues.
Other than that I sort of agree with you, notwithstanding the changes in SQL 2012 with mirroring and availability groups.
I hasten to add that I've worked with clustered production systems for as long as I can remember, I guess it would probably be SQL 7 when I last had stand alone production servers.
I do like the point about the DR server being a single node cluster, however my DR site does not have the benefit of a SAN or other shared storage.
Well, I have to throw a wrench here:
Clustering components have had a *lot* of bad reputation in the past let alone more failure surface.
In the latest editions that has changed but I can't forget all those nights that "ping-pong" issues affected me in the past.
Baring that, it sounds like something to think about.
There are two huge problems with clustering - (a) requirement for external storage wipes out PCIE ioDrives (internal storage) which means you can't use the fastest, lowest cost storage available and (b) management costs are significantly increased with clustering, due to the issue noel has alluded to.
I am generally an advocate for achieving simplicity through quality process & simplified use of technology rather than complicating High Availability technology, just to achieve automatic fail over (which usually results in increased incidence of fail over, therefore down time & even worse, more calamity when things go truely wrong.
Your idea is certainly creative but I think the costs outweigh the benefits
I meant to say that I advocate achieving High Availability through simplified use of technology & implementing quality processes rather than using complicated High Availability merely to achieve automation of fail over (what clustering essentially is).
In our experience, there is a glaring story of DBAs having to spend significantly more time supporting clustered SQL instances than non-clustered ones. One of the most commong problems is that storage engineers constantly screw you over with promises that patch upgrades to their firmware won't require down time. There's also the inherent extra complexity involved with clustering technology which has more cogs & generally breaks more often on its own
only problem i see with that is if you have something ridiculously expensive like EMC SAN's then you are spending a lot more on storage than you need to
We've seen the issue with the complexity of clusters doing us no favors. Some other things to consider.
With clustering, you lose shared memory as a network library. Now, if all of your processes are connecting from other systems, this isn't a loss. But if you have anything running local, it is. And it can be potentially affected by anything that plays with the network stack. We've been burned by that, and even with MS Premier Support were caught where we couldn't diagnose the real cause of a general network error with SSIS packages where SQL Server was up and responsive but the SSIS package stopped being able to talk to it. Move the packages over to a non-clustered server (where SQL Server was installed locally and the packages were talking to it) and everything was fine.
Also, if you're going the virtualization route, such as with VMware, the HA provided by such solutions may be more viable. We did a recent test where we intentionally moved the VM over from one physical host to another to simulate the scenario where we had to work on a physical host or the vSphere installation itself. While it took a good bit of time to get over, about 20 minutes for 192 GB of RAM on the new HP DL 580 G7s, the downtime visible to the clients was 600 ms, which is significantly smaller than the seconds one would see in a cluster fail-over. Now, we still want to see POST times for spinning up because we doubt that would be faster than a fail-over situation where the host unexpectedly died on you, but we know it'll be quicker than a cold boot since the server would have already undergone its POST cycle during power on and the POST is only in the VM.
Virtualisation has its own benefits & drawbacks.
One of the biggest draw backs is that it adds an extra layer of poorly co-ordinated multi-tasking which impacts performance all of the time, which can be much worse in many cases than the overhead associated with communicating over a network protocol vs shared memory (compute intensive vs network intensive workloads).
Both clustering & virtualisation are technologies which provide small benefits to a few support staff in the rare event of which hurting performance for all users all of the time.
I much prefer giving users good performance all of the time & having to do a little extra work as a DBA to achieve excellent High Availability through excellent process rather than just throwing a few very complicated, expensive technologies around
Major benifit of having a cluster is in case sql server is hung for whatever reason cluster will try to restart it....it helps a lot when you dont have to getup in night and able to meet SLA better
But on downside its the licensing cost which matters, even though sql server supports 2 node cluster with std edition windows does not.
Regarding shared storage since iscsi is supported its less of a struggle...we are using iscsi protocal for clustrers in vm's and working fine (small customners do not need top notch performance)
Once 2012 is available I plan to run everything on PCI2.0 ssd storage and have availability group configured for perfect HA solution...(though I prefer VM anyday as for 90% of sql prod servers I dont need to provide top notch performance or HA)
Prakash, your first paragraph represents a common approach taken by many DBAs - automation of fail-over in the hope that "whatever reason" will go away with a simple restart (which clustering automates).
But this is NOT how to go about High Availability, for two major reasons:
a) it implies acceptance of restarts (involving downtime) for "whatever reason". What this usually means is more frequent downtime than is necessary as "whatever reason" becomes a reason to restart when the whole objective of HA is to AVOID restarts & downtime. You might not want to be woken in the middle of the night, but unless you take the time to look into the problem (usually as it's occurring) you are far less likely to diganose it properly & therefore less likely to avoid it in future.
b) you expect a restart to solve problems, which just doesn't work & is hardly what DBAs are paid to do.
You did say that you don't need top notch performance or HA, and you certainly won't get it with this approach. The path toward getting good performance and HA out of SQL Server is to LIMIT the incidence of downtime & restarts by AVOIDing the problems in the first place, not simply automating the process of restarts.
Its a relatively easy thing to role out complex technology to automate the process of failover. Being proactive about avoding problems in the first place is a much bigger task, requiring more skill & experience as it requires knowing more about what NOT to do than what TO do.. Clustering falls into the bracket of what NOT to do in most cases when striving for high performance and availability, though you did state that these weren't your goals I guess..
Some interesting points raised here around HA in general.
Linchi - you wrote about this before and I think it's a great idea.
But then all of my data storage is provided by a SAN at the backend anyway, so no biggie for me to throw a cluster at a single-node.
My experience must be atypical since I've had no problems with clustering at all. But we do have a standard build so it all seems to just work.
SANs are expensive and not particularly fast when shared, but that's what we've got so the shared-storage prerequisite doesn't bother me.
Greg - Not sure that PCIio is the 'lowest cost' storage, but it is nice kit.
Also, on the general use of clustering: I use it to protect against hardware failure , so the automation of failover in that scenario is actually quite valuable to me (relatively rare I admit, but then so is loss of a datacenter and we still provide DR). It's handy to minimise downtime when the server team need to do OS patching as well. Greg - in the absence of clustering and virtualisation, what excellent processes do you use to provide HA?
I had high hopes for availability groups to overhaul the whole clustering/log-shipping/seamless-failover thing (the main benefit of the indirection provided by Linchi's post here), but if I thought the current crop was expensive, the new EE licensing model is mental and blows any possibility of me implementing that. So it's back to the drawing board to figure out the 2012 HA picture...
Is there a problem with this site at the moment? Whenever I try to post responses to this thread longer than a single line it bombs with a http 403 - Forbidden error..
There is nothing glorious about SQL clustering atleast as of sql 2008.
A failover mechanism which is at best primitive and very rudimentary. The isalive chek failing for 180 secs and there we go - restart.
If a DB had too many open transactions (think of batch job at night) and if failover happenned .. its likely that before the DB recovers the isalive starts failing again and another failover. I have personally looked at the server where this ping pong nonsense continued for hrs before someone knew how to stop it.
Call MSFT support if you have ANY unexplained outage on SQL cluster - their answer is same. Not sufficient data! Here is PSSDIAG and sqldumper (If sqldumper is so important not sure why its not enabled by default) and lets collect the data on the next outage. On next outage you provide the logs and the answer is 'SQL was healty' possibly something at OS/network stack. let me involve the xyz team. An option for low level tracing for isalive chek is something that clusering needs. I have some very bad experiences.
If my DBA recommends clustering for all the SQL servers - I will have him fired!
It is a bad idea to post some ideas like this one on this website - just to post something (it looks like was the main goal. right?)
<I believe it is a good practice to cluster all the SQL Server instances>
It does not make much sense ..
- It can confuse some not experienced DBAs just by the one reason -- > it was posted on the sqlblog.com..
I agree with SQLKID
Clustering is not perfect and is far from being perfect. But having too many open transactions is certainly not the root cause for an instance to bounce between the nodes. If you have actually checked how the IsAlive check works, you should know that many open transactions in the user databases will not cause the IsAlive check to fail. The IsAlive check is rather simple, and doesn't really touch the user databases. It doesn't matter how long it may take to recover a user database, how many transactions it may have to recover in a user database, or whether it can recover a user database at all.
Before you discount clustering SQL Server, you may want to be more precise on exactly why its problems may outweigh its benefits.
It is easy to present the case that the problems out weigh the benefits with clustering
It's as simple as pointing out that users are forced to experience degraded performance due to clustering's external storage dependency, purely so that a few maintenance staff don't have to be woken up at night in the rare event of a failure.
As users suffer degraded performance all of the time from clustering, its hard to build a case that the automated fail-over capabilities in clustering are actually a benefit, as failures should be very rare and there are options which don't affect performance yet merely pose some maintenance inconvenience for support staff (eg Log Shipping)
Then, there's the whole wider picture of increased complexity with clustering & the added faults this brings.
Worst of all however are SAN engineers who routinely bring down clusters, with no option of failover, under-mining the entire idea.
I think in most places whether or not you have an external SAN storage is orthogonal to SQL clustering. And in most of these places, SAN is a given and SQL clustering comes later.
True, mainstream SAN storage systems trade performance for manageability and so on in many respects. But it's my experience that a properly maintained SAN storage system should offer sufficient performance capacity for the vast majority of the apps. Where your performance requirements exceed what a SAN storage system can offer, sure you need to consider a different solution.
>Where your performance requirements exceed what a SAN storage system can offer, sure you need to consider a different solution.<
This doesn't make sense at all - why would you start with the most expensive, slowest solution (SAN) & then move to the fastest & cheapest solution when you could always have started with the fastest & cheapest solution (SSD)?
It is absurd to deliberately choose the most expensive & slowest solution, especially if the objective is only to implement clustering, which should really be seen as the High Availability inhibitor that it is.. All it does is automate failover, which is not the same thing as achieving high levels of availability.
You never pick an enterprise storage system on performance alone. Nor do you pick a storage system just because it offers highest performance. SAN storage systems offer many features to simplify managing your storage across the entire enterprise. If you condsider these features important, you have to pay for them. If you don't consider them important, SAN storage systems are not for you and would be a waste.
Nobody chooses an expensive SAN storage solution just to implement clustering. If your environment doesn't support failover clustering, you probably don't want to incur a huge expensive just to be able to put in clustering. But a lot of environments these days already have some sort of SAN storage systems in place. At least, all the places I have worked at have SAN storage systems.
I agree that automated failover is not the same thing as achiving HA, but it's one aspect of HA.
I'm not sure why we are even discussing this. If you don't like clustering or had bad experience with clustering, stay away from it and find a different solution to cover what it is supposed to cover. I'm telling my own experience, not rehashing any second-hand experience. And my experience is that for what it is supposed to cover, it's simple and effective, and I have not had any problems that would make me consider not cluster any important SQL instance.
I understand there are cases, for instance, where the availability requirement of a user database (not the instance) is such that failover clustering may not recover the user database fast enough, failover clustering may not be the solution and a technology such as database mirroring may be better.
You said yourself that SAN trades performance for manageability.
I say that any DBA who makes that trade off is making decisions in their own selfish interests rather than that of their users, who have to suffer the consequences of poorly performing, expensive SAN storage solutions all day every day, just so the DBA might get a little extra sleep
Users interests should come first but they rarely get a say in storage decisions, as DBAs & storage engineers often are the only ones at the table & tend to only represent their interests.
As for the "enterprise" aspect in this discussion - I prefer not to make a distinction between "enterprise" & "non-enterprise" as I consider this elitist talk that has no merit. All users deserve the best performance possible from whatever budget is available for infrastructure & SANs are theh worst choice in nearly all circumstances.
Your last comments about failover clustering not recovering the database fast enough have really missed the point. Failover clustering causes MORE outage time due to its inherent design. The increased complexity causes greater amounts of down time when faults occur as most faults occur in storage (which clustering can do nothing about) and when problems occur, they tend to be more complex & time consuming to resolve.
High Availability has little to do with recovery time - the main game is avoidance of problems in the first place and increasing complexity (eg clustering) works against the basic objective of keeping systems up in the first place.
The performance implications of external storage are a seperate but very commonly over looked problem & frankly, should be enough of an issue on their own to sway almost any decision about infrastructure away from clustering.
It looks like we just have had very different experience with clustering and external storage.
"Users interests should come first but they rarely get a say in storage decisions, as DBAs & storage engineers often are the only ones at the table & tend to only represent their interests."
You know this is simply not my experience, not at all. If DBAs are at the table at all, they would be the last one. In my own experience, they are never at the table for the enterprise storage decision. It's simply not a decision that would involve DBAs. Like it or not, they are too far down the food chain to have any real influence. Sure, DBAs may get invited to participate in the ritual afterwards, or in the process of determining how to best use it.
"High Availability has little to do with recovery time - the main game is avoidance of problems in the first place"
Not sure about the systems you have worked with. But I don't know how to avoid such failures as CPU or memory module failure or any failure inside the host computer. You talk about performance. There is actual a case for performance. And that is, sometimes memory modules go bad without outright failure. the end result is that performance is degraded. Having a cluster allows you to quick move your SQL instance to another node without having to live with the degraded hardware performance.
You brought up the complexity of clustering being an issue. This may be the case many years ago. But these days, clustering is rather simple and stable. You build it and forget about it. Again that's just my own experience. Yours may differ, and obviously are different.
When it comes to external storage, the fact of life is that they are there in all major enterprises and they are not going away any time soon. I don't think we have any choice but to live with them. As I mentioned before, to us database folks, they are more or less a given. So why not take full advanatge of it?
BTW, without external central storage, how do you achieve such things as storage on demand and automatic tiering? Or do you consider those feature not really worth having?
Linchi, correct me if I'm wrong but my undestanding of your background is that you've worked predominently on Wall St & perhaps things are done in a certain way there, but this isn't representative of most of the business world.
Talking about "enterprise" practises is elitist & an un-necessarily intimidating terminology.
Whilst I understand that the larger an organisation is, the more likely they homogenise their approach to storage but there is also the other reality with such big businesses - that many of their internal customers suffer from terrible experiences from centralised IT services & end up "silo"ing their systems onto their own infrastructure to get away from such homogenised approaches.
After working with SQL Server systems for nearly 20 years & running a dedicated SQL Server support business for the past decade with customers all over the globe, in all major industries & of all sizes I put it to you that most businesses don't operate the way Wall St businesses do & to the vast majority of businesses, end user performance is extremely important, usually more than centralisation of storage.
In my opinoin, your idea of every server being clustered would bring much damage to anybody who followed it. You indicated in your opening sentence that you expected others to disagree so this probably doesn't even surprise you.
(part II of a previous post which SQLBlog.com wouldn't let me post as a single post for whatever reason)..
As for your last question about storage on demand & automatic tiering, first - these are phenomenon's that mainly apply to the super expensive SAN's which you seem to work with. They are so expensive, storage needs to be provisioned only on demand & tiered so that investments can be recovered on equipment only as it ages.
With dedicated storage, it's usually feasible to invest in sufficient storage for the life expectancy of the system & it is also usually expandable sufficiently when needed. Individual PCIE ioDrives are currently available in 5TB format & capacity is growing regularly. It is feasible to have many of these in a single machine so internal expansion is a definite reality. Tiering isn't so crucial as it is with SANs as there's not such as huge requirement to recover capital investment in the equipment (as it's so much cheaper).
Hi Greg
Well, if you don't like SANs, why don't you just say so!
It's all very well calling 'Enterprise' practices 'elitist', but you know what, that's the actual world that lots of DBAs in big organisations live in. 'Enterprise' exists as real stuff in the real world. Once you reach a certain scale your technology options change.
Yes, I'd love to throw FusionIO into everything, but I am forbidden to use local storage. End of story. It's all SAN. And that's a decision taken way over my head and is justified on the basis of management of storage infrastructure in general, not database storage in particular. If I can *prove* that the SAN cannot provide the IOPS for a specific database then I might have a chance of having a niche exception case. But actually, for practically all of my systems, the SAN is absolutely fine. And while we're at it, Virtualisation is perfectly adequate for the most part too.
I actually have some sympathy with your position. SANs are expensive and slow. Although to be fair, they are generally reliable and our SAN team doesn't randomly fail my systems - which seems to be your experience.
Finally, the suggestion that I'm both 'lazy' and 'selfish' because of how I choose to implement my HA is frankly astonishing. I have an entire Risk department looking over my shoulder that I have to satisfy on system availability. They report to a government agency. I prefer to have my recovery automated.
I asked earlier what 'excellent' procedures you use to guarantee availability in the event of failure - I'm still curious about that. If a better option exists then I would love to hear about it.
A properly designed system on properly managed infrastructure will perform appropriately. Your specific experience doesn't define the general rule.
I actually put together a response to your earlier question about achieving high availability through process but SQLBlog.com wouldn't let me post it. I received HTTP 403 errors numerous times, despite trying to break the content down to smaller posts etc. I'm not sure why this happened but after trying for some time I gave up.
I'm not sure why you would draw a personal inference from my comments about laziness, when you've expressed that you had no say in the storage decision where you work. I wasn't referring to individuals specifically other than perhaps Prakesh who said he wanted to avoid having to get up to meet asn SLA.
It was intended as a general comment about infrastructure design which I think holds true - High Availability is often designed more for the convenience of support staff without due consideration for impact on user experience.
I also think there's a nerdy curiosity with technologies such as clustering which are perceived as "advanced" and IT engineers want to deploy the technologies sometimes for no better reason than to gain experience or be able to put on their resume that they've implemented a complext technology. Again, without due consideration for end user experience..
Anyway, this post was primarily about clustering being used for EVERY instance of SQL Server & my position on it is that the storage performance trade off is not worth the benefits Linchi has outlined.
Sure, not everyone can switch from SAN to SSD, but my point is simply that clustering requires external storage and therefore rules out the best performing & value for money storage available. When it comes to DBMS servers, this is a huge trade off & not worth the benefits Linchi has outlined.
I might have misunderstood you, but you seem to see a dichotomy between "convenience of support staff" vs. "user experience". I happen to think making the life of the support staff easier enhances the user experience. In addition, if we don't consider the impact on user experience, the convenience of the support staff will be greatly hurt.
You also seem to view SAN and SSD as mutually exclusive. They are not. Modern disk arrays from all major vendors can have tons of SSD in them, plus tons of cache. Centralized storage behind a SAN may be slower (compared to what you can do with the storage devices when you are totally unconstrained). But unless you are doing some fancy stuff in there (e.g. synchronous storage replication between two sites at a distance), it's actually hard to find an app that can't live with its performance. If you disagree, please provide an example.
You know one of the hardest things in IT is to predict demand accurately and consistently. You may have success in predicting how much storage is needed by an app and translate that into how much storage to allocate to a server. But I have not had such success and I don't know anyone who consistently has such success. The truth is that you can't because there are always unexpected events that demand storage right away. You could have a sudden corruptuion in a large database and you want 4TB of extra storage somewhere quick just to be able to check the database out. You could have a sudden court order to retrieve some old stuff from an archived database that you need storage to restore from the backup. A centralized storage system gives you a very large pool so that you don't have to make any prediction at a very granular level. You get what you wnat and you don't even have to mess with the server itself. And if your prediction turns out to be too excessive, just give what you don't need back to the pool. This is exactly like having a centralized power grid. I'm sure people argued about pros and cons of having a centralized power grid, and some may still be arguing. But for the vast majority of us, we just enjoy being able to hit the light switch and have our houses lit without having to worry about if we need to add another power generator. That's excellent user experience, if you ask me.
Fair enough response, based on the fact that I didn't choose the storage. I didn't make the distinction when I first read through your posts.
On the other hand, if I was given the option today of throwing away the SAN and replacing it all with PCIio, would I? Probably not. Not exclusively anyway - maybe for one or two systems. For the simple reason that the current system works fine. Any system is a collection of compromises. If a query runs in 100ms vs 50ms, is that important? Depends on concurrency, frequency of use, etc etc. Balance that against the fact that I survive a hardware failure. Probably the SAN is fine.
I'm not using clustering as a CV++ tool. I have challenging RTOs during the working week - particularly overnight. Yes, I could use mirroring perhaps, or AGs in 2012. To my mind they're more complex than clustering.
Anyway, I guess it's a matter of perspective. If I had a small greenfield site, would I buy a SAN for my databases, with my own money. Maybe not.
If I'm in a company where I have to use a SAN for all of my database storage, am I bothered? As long as the disk performance is appropriate (and that doesn't mean as fast as it possibly can be) then probably not.
Getting back to the orginal topic - Clustering is not, in my experience, flaky or unreliable or overly complex. If I have SAN storage sitting behind all of my servers anyway, then I suffer no performance penalty for making each a cluster, and I get the benefits that Linchi talks about. And I think this is where Linchi is coming from.
@Linchi, I never said SAN & SSD are mutually exclusive & neither did I say that support effort vs user experience are a dichotomy.
What I did say is that clusters eliminate the best cost / performance storage option, which is PCIE attached ioDrives for most systems. This is not the same as saying SAN & SSD are mutually exclusive so I'm not sure why you read further into my comments beyond what I actually stated.
As for the support effort vs user experience discussion, it is perfectly possible to achieve both (this is the core of what my company MyDBA does for its clients). The question is HOW you go about doing this & through extensive experience, I have learned that automation of failover & recovery via clustering generally does more harm than good.
Sure, clustering can automate recovery, but it also generates more down time than alternatives as it is overly sensitive to conditions that cause failovers - which other readers of this blog have pointed out can cost you transactions.
I have not said that clustering or SAN should NEVER be used. My point was that clustering should not ALWAYS be used (the topic of this blog).
As for your comments about provisioning storage on demand through SAN, most readers of your blog will recognise the extreme cost in this approach. Perhaps Wall St companies with too much money can keep expensive SAN capacity sitting idle in case somebody might want it someday, but most companies would approach this problem more practically.
For example, one of our clients is a UK based law firm (one of the largest law firms in the world) & had a corrupt multi-TB evidence database resulting from a SAN fault. The firm was involved in an international class action & had to respond to discovery procedure requirements quickly & their backups were also corrupt (same SAN). The practical response was to simply provision another server & storage to get on with this time critical task, which we completed without delay.
I bring this example up to show that even in extreme legal, time-critical cases, SAN provisioning isn't neceesary as hardware can be provisioned quickly enough when needed.
In my experience, very often SAN engineers are actually SLOWER at provisioning SAN storage than storage can be bought. This is usually becasue SAN technology is SO EXPENSIVE that very few firms are prepared to waste money keeping sufficient excess capacity available for ondemand storage. Most SAN storage teams put up a fight just to provision SAN storage, yet you describe it as if on demand provisioning through SAN is easy.. I put it to you that your experience is high unusual
Most companies are more practical & budget conscious. We are a long way off topic however & I am not totally opposed to either clustering or SANs.
My main response to your blog is that clustering should not ALWAYS be used, which is the extreme position you have presented in this blog.
I would go further to say that the cases for clustering SQL Server systems are actually reasonably rare & with the improvements to Live Migration coming in Windows 8 Hyper-V, I think the reasons to cluster systems will be reduced even further
@Ewan, I think you're presenting a reasonably balanced position & I think we actually agree. I don't object to technologies being used where they are appropriate & I also don't think that performance extremes always need to be achieved. Where 100ms is good enough, fair enough but it's important to recognise that there are MANY systems out there that need extreme performance from whatever budget they have & clustering is an inhibitor to this.
My point is that clustering should not ALWAYS be used.
Do you agree with Linchi that clustering should ALWAYS be used?
I'll refer back to my previous post: where you already have SANs backing your servers, my view is that the benefits provided by clustering justify its use. Always. Namely, indirection and aliasing provided by the network name resource. Maybe if I had admin rights over DNS and AD I could automate this easily (I don't know), but clustering gives me this out of the box. Even (and in this context especially) in a single-node configuration.
I accept that there will be many systems that require massive performance and therefore any shared storage model is inappropriate. But I have only ever come across one (and I work in a large Financial Services firm in the UK, so I expect I work with reasonably high-end requirements). Which means the 700 systems I currently support are entitled to define the general rule, which I'm happy to reject on an exception basis.
Re-reading your posts, I think your issue is with SANs in general as opposed to clustering. Clustering, to you, is merely problematic bacuse there's a SAN involved. Would that be fair?
I reckon that most companies that have spent 500k on a SAN has reasonable capacity to flex. The disks, although expensive, are the cheapest part of the thing. But my expectation of logic may be unreasonable - I've plenty of experience of idiocy after all. For my part, I have a pool of database storage that I 'own'. I can carve stuff out of it as I need, so perhaps it's ownership of the storage that causes issues.
And I suspect Live Migration won't be much of a panacea - I certainly don't expect it to replace any clustering implementation I have. VMWare have had it for a while and it has never suggested itself to me as a solution.
Good discussion this, btw. Thanks for sticking with it.
This is a very interesting article. Personally, I've had some mixed experiences with SQL clustering, starting with SQL 7. Clustering works very well when done correctly, and it has gotten a lot easier over the years to do correctly. But for all versions of SQL, I've seen major issues with clustering caused by lack of experience on the part of the people installing and maintaining the cluster. So that is just one reason I would not advise clustering in every situation.
Just a small point about what SQLKID said: a clustered instance can fail because of user connections. SQL only allows roughly 32 thousand connections, and if all connections are used, the IsAlive can no longer connect to perform its check. This will definitely lead to a failover.
Just came across this post and wanted to add
- It's certainly a very interesting idea I want to try - cluster every SQL "physical" instance - that makes moving much easier when you move
We are all SAN for physical anyway (but NFS for VM)
- I was told by MSFT PFE recently some companied even P2V their 2-node cluster into a VM, and took out physical node = 1-node cluster VM
Although in some environment, it may just be down to
Tier 1 - cluster on physical - b/c of HA requirement
Tier 2+ - VM - b/c it's not important enough
then we don't have to worry about 1-node cluster :)
I don't think SQL Server Cluster is greate enough.
the cluster ware may be weak point

I haven't yet had a chance to work on Windows 7. Although for many months now, I have had some second-hand experience of using it. The developers I work with, my coworkers, and my tweples – everyone's talking about Windows 7 on the other laptop or the new PC.
Apart from substantiating the general euphoria about the interface and the speed, the comments or the tweets sometimes highlight pain points, many of which are compatibility issues and have a quick fix or workaround.
In a recent blog post, Rick Stone talks about one compatibility issue that our Help users are likely to encounter. Many HTML pages have Captivate demos inserted in them. If you are running Windows 7, you might find that these demos are not appearing (instead, there's a large placeholder).

Hello, I'm the Merry Lurker.
I have a question about Python and how it interacts with Web Pages on the plain-text level. I have a little bit of basic Python knowledge, but before I go further into my project, I was hoping some of you could help me figure out whether Python is what I need.
Let me tell you a little about my project. Rather than use a traditional game engine, I'm trying to build a game that operates out of a web-page. The game will utilize image maps, pop-up windows, user-manipulated moving images, chat, normal login/out account features, and possibly cookies. All this needs to be done live, without refreshing the entire page, and in sync with calculations outside the page (such as damage counting). My goal in doing it this way is to create a simple multiplayer game that can be accessed on any device, does not require the player to download anything, and can store its image files on third-party servers.
Is it possible to support this kind of duct-tape and chicken-wire rig by using plain Python 3 in conjunction with a webpage, without using a special add-on (like pygames) or GUI?

Aug. 26, 2010
Game Warden named Texas Wildlife Officer of the Year
AUSTIN – Long-time Texas Parks and Wildlife Game Warden Arthur McCall of Pleasanton has been recognized as Texas Wildlife Officer of the Year by Shikar-Safari Club International.
TPWD Executive Director Carter Smith, along with club president Happy Rogers and board member Louis Stumberg, presented the veteran wildlife law enforcement officer the prestigious award at today's meeting of the Parks and Wildlife Commission in San Antonio. This marks the 31st year this award has gone to a deserving Texas game warden.
"As a leader, Arthur shares his experience and expertise with younger wardens and continues to be a mentor to them," Smith said. "His dedication and commitment to protecting the natural and cultural resources of the state of Texas have made him a role model in his community and in the field of law enforcement."
McCall graduated from the 23rd Texas Game Warden Training Academy in 1969. After an initial assignment to Real County, he transferred to Atascosa County in 1971 and that has remained his duty station.
During his 41-plus-year career McCall has been commended numerous times for his professionalism. He consistently takes part in the "Who Done It Camps" and coordinates hunting trips for underprivileged kids as part of the TPWD Law Enforcement Division's public outreach activities.
In the enforcement side, McCall participated in the arrest of multiple violators of a poaching ring in South Texas, part of a covert operation dubbed "Venado Macho." More recently he conducted an investigation stemming from an Operation Game Thief call that resulted in the prosecution of an individual who killed two bucks in a one buck county. Restitution on the case came to more than $5,000.
McCall is one of the founding members of the Texas Game Warden Honor Guard. In 2007, the Honor Guard received the TPWD Outstanding Team Award for its commitment and dedication in performing at numerous events around the state, including ceremonies for fallen officers. Additionally, he is the Honor Guard's rifle squad leader.
When not enforcing the law, McCall is also a very accomplished artist and is represented by the Mooney Gallery in San Antonio. His work has three times been selected as the poster-print for the San Antonio Stock Show and Rodeo.

U.S. Secretary of Defense Leon Panetta last month said his department is developing forensics to identify the sources of cyber attacks—addressing the longstanding and key concern that cyber attackers who hit the U.S. might be able to hide their identities.
But the head of Russia's biggest antivirus software company isn't sure the forensics will work.
Eugene Kaspersky, Chief Executive of Kaspersky Lab, whose products are used on more than 300 million systems worldwide, says users of the attack-attribution techniques that he is aware of can still be fooled.
Last month, in a speech at a dinner event held by the Business Executives for National Security group, Mr. Panetta said the U.S. Defense Department is seeing returns on investments it has made in forensic capabilities to locate the sources of cyber attacks. "Potential aggressors should be aware that the United States has the capacity to locate them and hold them accountable for actions that harm America or its interests," Mr. Panetta said, according to a copy of his prepared remarks.
Mr. Panetta didn't elaborate on how the U.S. forensics work.
Mr. Kaspersky probably doesn't know exactly what technical measures the U.S. government is using to trace cyber attacks. And U.S. human intelligence capabilities may be able to confirm the sources of attacks on the U.S., without the need for any digital detective work.
Still, Mr. Kaspersky expressed doubt that any forensic techniques could put to rest the challenge of attributing attacks.
"I'm afraid it's possible to design [a cyber attack] in such a way that" its source could remain hidden, Mr. Kaspersky told a small group of reporters over dinner at a steakhouse in Chicago, when asked about Mr. Panetta's remarks.
Cyber attackers often hide their location by using proxy servers, which essentially route an Internet connection through another place. Private companies that provide attack-attribution services use techniques to "bypass" proxy servers and find the original source of an attack, Mr. Kaspersky said. But sophisticated attackers can still manipulate the findings that such methods will produce, he said.
Mr. Kaspersky declined to explain how, or to elaborate on other ways that attackers could hide their tracks from forensic tracing. He said he would only speak about the issue with governments.
Mr. Kaspersky's company has faced suspicions of ties to the Russian government. In July, in response to a Wired profile of Mr. Kaspersky that discussed those concerns, he wrote on his blog that top security companies like his all work with law-enforcement bodies. But he likened the relationship to that of Indiana Jones when called on by the U.S. military. "It's the same for what we do for governments worldwide today – we provide EXPERTISE. Nothing more," he wrote.
Also during the interview in Chicago, Mr. Kaspersky said he has dropped his objections to the Budapest Convention, a 2001 treaty that was the first on cybercrime.
Mr. Kaspersky in the past has voiced opposition to the convention, echoing concerns that the Russian and Chinese governments have raised about one of its articles in particular.
The Budapest Convention aims to harmonize cybercrime laws among its members and to make it easier for law enforcement agencies to help each other in investigations. The convention has been signed and ratified by 37 countries so far, including many European countries, plus the U.S. and Japan.
Mr. Kaspersky said he used to oppose the convention because of an article that allows members to access data stored on computer systems in other countries. But after representatives of the convention clarified to him that this can only be done with the consent of the system owner, Mr. Kaspersky said, he changed his mind.
"I personally support [the] Budapest Convention," Mr. Kaspersky said, adding that its existence could help Interpol in cyber investigations.
It "is a very good idea to have a legal framework for international cooperation," he said.

Carolina's golf teams also have an outstanding team facility, the Chapman Golf Center, which opened in November 2001 and underwent further renovations in the summer of 2010. The 4,500-square-foot facility houses offices for the men's and women's golf coaches, men's and women's locker rooms, a team meeting room and a reception area. There is also a climate controlled individual teaching area with two hitting bays and a state-of-the-art teaching system. At the far end of the range adjacent to the team facility is the Williamson Golf Team Practice Facility used exclusively by the men's and women's golf teams. In addition to a practice range, there are putting and chipping greens as well as bunkers so the teams can hone their short games. All of these superb facilities are located just minutes from Carolina's campus.

"Ordered a sample in the yellow. Paper quality is great. Paper is a little crinkly (ordered the basic paper) which I like. Paper stands up well. Love the colors. The website mock up is pretty darn close to the actual colors which is great!!"
"These place cards turned out beautifully. I had to order 3 colors to coordinate to entree choice for my venue. I picked a custom color for my third choice and the customer service team automatically picked a second color as accent."
"I ordered invitations with this same design and decided later to purchase the name cards. The match was great -- loved the fact that the design was on both the front and back of the cards. Only downside is that I was unable to remove the "table ______" from the design. Not a big deal for me."
"Matched perfectly to stickers of the same design used for cookie favors. Service and shipping time was excellent. Would highly recommend this company."

A new study published today has strengthened the case for smokefree legislation to be extended to include all bars.
Quit Executive Director Todd Harper says the new study, published in the British Medical Journal's Tobacco Control publication, has good news for pubs and clubs.
'The important finding of this new research is that studies published around the world that use verifiable, objective data like sales and employment figures found smokefree policies have no negative impact.'
'However, studies which found smokefree policies have a negative economic impact were almost always funded by the tobacco industry, and were based mainly on opinions and predictions rather than hard data.'
'Unfortunately the tobacco industry has mislead the hospitality industry and the public. This study suggests that the industry has used very questionable research in attempts to alarm proprietors and scare off legislations contemplating smokefree policies in restaurants, bars and clubs'
'Indeed, this study revealed that two surveys funded by the tobacco industry which found that more people would attend smokefree venues were not released publicly.'
'Unfortunately for those workers who still have to endure smoky workplaces, the tobacco industry's scaremongering has delayed the introduction of smokefree policies.'
'The most important thing to remember is that smokefree venues are healthier for staff and patrons, and the public health benefits need to be the main consideration.'
'We've seen tremendous progress on this issue recently, but no one should have to risk their health to go to work.'
'Making all indoor workplaces smokefree as quickly as possible should be a priority for employers and governments.'
Mr Harper said that recent reports of a downturn in gambling revenue in Victoria following the introduction of smokefree legislation need to be treated cautiously.
'After only 5 months it's just too early to tell whether the reported drop in gambling revenue is solely the result of the new policy, or if it's permanent.'
'It's not surprising that there would be a short term effect, but it's too soon to say if this effect will be long term.'

48 JIMMIE JOHNSON, Chevrolet
Team: Hendrick Motorsports
WHERE HE STANDS: After being tied with Matt Kenseth heading into this past Sunday's race at Texas, Jimmie Johnson regained sole possession of first place. He leads Kenseth by seven points and is 40 points ahead of third-ranked Kevin Harvick.
PHOENIX RECORD: 20 career starts, 4 wins, 13 top-5s, 16 top-10s, 1 pole. Best career finish: First in fall 2007, spring 2008, fall 2008 and fall 2009. Finished 32nd in this race last year and was second in this year's spring race there.
LOOKING AHEAD: Johnson knows his slim lead over Kenseth means virtually nothing. Here's his thoughts on Sunday's race at PIR, which is one of his best tracks: "There's still a lot of racing left, and the two tracks that remain on the schedule are very challenging tracks. Last year we were in this situation with a points lead. We had a seven point lead going into Phoenix and had a very bad race and blew a right front tire. Actually had a decent race going but blew out a right front tire and hammered the wall. It really hurt our opportunity and our chance to win a sixth championship then. So I'm just not going to put my guard down. We need to go into Phoenix, race well. We finished second there in the spring, so we feel strong about our setup and the performance we should have there, but that doesn't guarantee us anything, and we need to go out and have a good strong, clean weekend."
LOOKING BACK: Johnson did what he had to do at Texas, dominating the race - led 255 of 334 laps -- en route to his sixth win of the season, one less than Matt Kenseth's seven wins.
ETC.: Johnson has completed 99.4 percent (6,282) of the 6,321 total laps contested in 20 career starts at Phoenix. His average start there is 12.5 and his average finish is an outstanding 6.4. He has zero DNFs there.
20 MATT KENSETH, Toyota
Team: Joe Gibbs Racing
WHERE HE STANDS: After being in a tie with Jimmie Johnson heading into this past Sunday's race at Texas, Kenseth left the Lone Star State in second place, seven points behind Johnson. He leads third-ranked Kevin Harvick by 33 points.
PHOENIX RECORD: 22 career starts, 1 wins, 5 top-fives, 9 top-10s, 1 poles. Best career finish: First in fall 2002. Finished 14th in this race last year and was seventh in this year's spring race there.
LOOKING AHEAD: Kenseth goes from what historically had been one of his best tracks (Texas) to one of his most marginal tracks (Phoenix). He can't leave PIR with more than a 10-point deficit between himself and Johnson, lest he may be too far away to catch Johnson in the season finale at Homestead next week. Here's Kenseth's thoughts on Sunday's pivotal race: "We're right in it (championship battle). As good as my team is, even if nobody has any trouble -- if we hit everything right we can have days like (Johnson) had (at Texas) and we've had them this year. I still feel good, I'm still confident. I wish I was seven points ahead, but at the end of the day it's in our hands."
LOOKING BACK: Try as he may, Kenseth just could not get closer to Johnson at Texas, ultimately finishing for a still very good fourth-place finish.
ETC.: Kenseth has struggled in his career at Phoenix, having completed just 91.4 percent (6,382) of the 6,945 total laps contested in 22 career starts at Phoenix. His average start is 20.1, while his average finish is a marginal 17.2. He has four DNFs there.
29 KEVIN HARVICK, Chevrolet
Team: Richard Childress Racing
WHERE HE STANDS: Kevin Harvick moved back into sole possession of third place after Texas. He trails points leader Jimmie Johnson by 40 points, second-ranked Matt Kenseth by 33 points and leads fourth-ranked Kyle Busch by 12 points.
PHOENIX RECORD: 21 career starts, 3 wins, 6 top-fives, 10 top-10s, 0 poles. Best career finish: First in spring and fall 2006 and fall 2012. Was first in this race last year and 13th in this year's spring race there.
LOOKING AHEAD: Phoenix has long been one of Harvick's best tracks and he's likely to have yet another strong finish there on Sunday. Here's his thoughts on the season's second-to-last race: "You really have to have an understanding of the track. Every time we go back, I feel like we learn something different. We really did well at Phoenix last year, and also ran well there earlier this season, but we didn't play the strategy game correctly at the end and lost the track position we needed. I feel like you have to play the strategy game; the track is still racy enough where you can make up time if your car is good, but you need to stay focused on strategy. Phoenix has done a great job redesigning the track. It's a great place for us as a team, but you have to play the game right with the strategy."

Paul Simon and Sting to tour together
Sting and Paul Simon are set to embark on a North American tour together in 2014. The rockers will kick-off Paul Simon & Sting: On Stage Together in February.
Announcing the joint tour, Sting tells The New York Times, "Paul and I both share this abiding curiosity about music and where it's going.
"We don't really know where this (tour) is going. We don't really have a clue how this is going to pan out."
In June (13), Simon surprised fans at Sting's concert in Atlantic City, New Jersey, when he joined the former The Police frontman onstage for renditions of Fields of Gold and Simon & Garfunkel's The Boxer.

I've never been let down by a Doctor Who finale. From the first season on they've always brought out the best in the series. I wasn't even bothered by the tiny-Doctor-made-big-by-people-wishing-it-so development in the last season. It was silly, but it worked. (Same goes for much of the show.) So maybe I came into this, the final finale shepherded by Russell Davies with too-high expectations. The season long build-up worked. Last week's prelude worked. I was still intrigued as to what was up with the bees. Also: Guest stars aplenty. This was going to be good.
And it was good. Enough. I watched this episode and next week's episode back-to-back, so pardon me if my feelings for both bleed together a bit. I'll try to get the facts this episode straight and save some of the opinion for next week. But as a bonus, I'll tell you about the Doctor Who panel I went to at Comic-Con yesterday. Deal?
We open, with a sense of urgency, on a familiar-looking suburb street. Although I'm not sure its familiarity is supposed to be part of the point. I just think the show is frugal. After the Doctor and Donna leave the TARDIS, return to the TARDIS, then attempt to leave again, they find the Earth has vanished beneath them. This can't be good. Cue the view from New York where Martha, and others try to figure out what's going on. Switch to Cardiff and Torchwood. Then to London and Sarah Jane and son. Then Chiswick and the Noble home. Enter Rose and a big-ass gun. It's as if Davies is gathering together all the pieces he's been moving around for several seasons, on this show and others. Clearly we're in for something.
Trouble is it's a bit too much of something big. We get Daleks and Space Rhinos (what are those guys called again? Judoon!) And a lot of people running around trying to accomplish stuff. There's scarcely a moment for anyone to catch their breath. The moment between Donna and the Shadow Architect is refreshing in its intimacy. Beyond that, it's mostly our heroes panicking, separately as we all build up to the revelation of Davros!
Davros? I'm the first to confess that my Who fandom only stretches back to 2005. I might seek to correct that some day but for now I'm fine being a newb even four seasons in. But that never mattered when it came to the introduction of Daleks, and Cybermen, and The Master. I caught up. It helped that those were all cool characters. Here we have a mean old guy in a chair. Which would also have been fine if he'd actually turned out to do more than he does But I'm getting ahead of myself.
And, to be fair, we end with no small amount of excitement. We get a Dalek rage and some regeneration, and other cool stuff that will pay off gangbusters next week. Right?
Grade: B
So, about that panel. It was supposed to feature Davies, Steven Moffatt, and executive producer Julie Gardner, but only Moffatt and Gardner showed, explaining that Davies was writing new Torchwood material, which got some cheers. Moffatt was totally charming and he and Gardner were fun together. As an example of their production process, they talked about the great back-and-forth concerning the "Girl In The Fireplace" episode, in particular the shot of the Doctor crashing through a mirror on a horse into a ballroom. Turns out it's not as easy to get a horse into a ballroom as you might expect.
Moffatt also related a funny story about getting stopped by airport security and then eluded any questions that might spoil future developments. But he did say this when asked if River Song recognized David Tennant's character as The Doctor or simply recognized the essence of The Doctor. He said he thought she had met the Tennant Doctor before but had also spent time with other Doctors. Is that an escape clause or a spoiler? You decide.

Live from Taiwan: ATI RD580 Motherboardsby Wesley Fink on 3/1/2006 8:55 AM EST

Beenthere - Saturday, March 04, 2006 - linkFor those silly enough to run out and buy an untested mobo, the ATI RD580 mobos don't seem to be readily available in the U.S. on March 1st as advertised. Today 3-4-06 I see only two e-tailers with a few of the Asus A8R32 and of course they are price gouging like usual. I don't see any of the Asus or other brands of RD580 mobos at Monarch, Mwave, or other larger e-tailers so it looks to me like some gray market mobos were shipped to the two e-tailers to be the first kids on the block to have them. ther's also no listing for the A8R32 on pricegrabber or Dealtime.
I also see from the reviews that the A8R32 offers little performance advantage over the A8R-MVP and few of the voltage/BIOS issues have been resolved. With the foolish PCI slot locations and number on the RD580 chipset based Asus, Sapphire mobos it looks like these mobos are of little value to anyone. More not ready for prime time rushed to market crap for the sheep to buy.
Ecmaster76 - Wednesday, March 01, 2006 - linkSeriously though, when is the performance review coming (back) ? Reply
DigitalFreak - Wednesday, March 01, 2006 - linkI can't believe Asus would only put 1 PCI-E 1x slot on this board, and then place it so it's useless when a dual slot cooler video card is installed! Whomever designed this board should be smacked. Reply
Palek - Tuesday, February 28, 2006 - linkWes, you say, "The Sapphire version is a virtual copy of the ATI Manta Reference design..."
I seem to recall (I could be wrong though) that Sapphire designs most or all reference boards for ATi, and if that is the case here then the above sentence might require some rewriting. Reply
breethon - Monday, February 27, 2006 - linkWhy all the hoopla when AMD is moving away from Socket 939? Is this "NEW" thing going to support the new 940s too? Otherwise, how can you support the idea for the cost? Reply
Aelius - Monday, February 27, 2006 - linkDid you even bother reader it?
R580 is not just socket 939. It is also for socket AM2, in fact many mobo manufacturers are only bringing this chipset out for socket AM2 and are skipping 939.
Personally I'm skipping AM2 altogeather and getting the best 939 system later this year when prices are much lower and laughing all the way to the next AMD socket generation after AM2. Should be in 2008. Reply
Orbs - Monday, February 27, 2006 - linkSince the RD580 is going to support AM2, it's definately a longer-term chipset. With all the recent hoopla regarding HDCP support, does the chipset itself need to be certified to enjoy HD output on Vista? If so, does the RD580 support it? Reply
DanaGoyette - Monday, February 27, 2006 - linkI want the Abit, but it's a shame the board is brown (brown is ugly). I want it in black like the Asus, with red or black slots. I can make the SATA external just by passing it through a PCI slot or a hole in the backplane. Reply
Missing Ghost - Monday, February 27, 2006 - linkThat DFI board looks like the most perfect board ever! Reply
ariafrost - Monday, February 27, 2006 - linkOr can you not access the ABIT page (should be page 4) of this article? It just takes me to the "bottom line". Reply
bupkus - Monday, February 27, 2006 - linkTry the Abit link on page 3. The page 4 link on the drop down list is broke. Reply
Gary Key - Monday, February 27, 2006 - linkThe links have been fixed. Thank you. Reply
Beenthere - Monday, February 27, 2006 - linkAfter the long list of mobo problems with the RD480 chipset mobos, which appear to be mobo design issues, not RD480 chipset issues, I wouldn't touch an RD580 chipset mobo with a ten foot pole.
AFAIK Asus, Sapphire and other mobo makers have provided no solutions to the long list of problems on their mobos. It's as if the mobo makers have no clue or no interest in their customers? You can go to any mobo maker's website and any hardware review site and find documented problems on these mobos that are inexcusable yet there have been no fixes provided by any of the mobo makers. If a mobo maker can't produce a mobo with a stable Vcore voltage, standard BIOS Vcore voltage options, run standard industry certified PC3200 memory, etc. then they're in the wrong business.
You can be certain if they couldn't fix the problems on the RD480 mobos, they haven't fixed the problems on the RD580 mobos being rushed to market just before the AM2 socket mobos will be released. My guess is if the mobo companies keep dumping crap in to the marketplace, they are gonna kill the market as anyone with a clue isn't gonna buy one defective mobo after another and then have to trash it because it can't even function properly at the default settings of all current AMD mobos. Since PC professionals and hardware review sites have confirmed these problems, it ain't user installation issues, but in reality, mobo design issues. That's why a BIOS upgrade can't fix the problems on the RD480 / RD580 based mobos. Reply
Wesley Fink - Monday, February 27, 2006 - linkThe RD480 had issues with supplying voltage to the x16 sklots in some Crossfire configurations. It was never really designed for dual slot - which was more an add-on. The RD580 was designed for dual slot from the ground up and is a very robust chipset. Reply
matthewfoley - Monday, February 27, 2006 - linkAgreed.
I have an Asus A8R-MVP, and I've seen the huge variance in the vCore - even at stock. Other than that it's a good value board, but I'll avoid ati's chipsets from here on as a result - not because it's a bad chipset, but because I don't feel the board manufacturers have given proper time to the design.
matthewfoley - Monday, February 27, 2006 - linkIt was up for a day or so then nothing. I'm guessing it will reappear on launch date. Reply
matthewfoley - Monday, February 27, 2006 - linkNow there isn't even a page on this review for the Asus A8R32-MVP. What's the deal? NDA? Reply
Gary Key - Monday, February 27, 2006 - linkThe article has been updated. Sorry about Page 1 missing for a moments. Reply
DigitalFreak - Monday, February 27, 2006 - linkNow if they would get rid of the stupid Master Card requirement for high end Crossfire setups, I'd buy one. Reply
DeanO - Monday, February 27, 2006 - link1st page - "The bargain-priced A8R32-MVP" should be "The bargain-priced A8R-MVP" Reply
Googer - Monday, February 27, 2006 - linkIt's hardly bargain priced at $200+ (according to froogle).
http://froogle.google.com/froogle?q=A8R32-MVP&...">http://froogle.google.com/froogle?q=A8R...a:en-US:... Reply
DeanO - Monday, February 27, 2006 - linkAnother one on page 2 - "competitive UDB performance" should be "competitive USB performance" Reply
Guuts - Monday, February 27, 2006 - linkAlso on page 1: "The value is even greater when you consider than the ATI Crossfire X1900XT and Crossfire X1900XT are the fastest video solutions currently on the market and they are fully supported by the A8R32-MVP."
"...when you consider THAT the...", and you've listed the same card twice, "...Crossfire X1900XT and Crossfire X1900XT..." Maybe throw another "X" in there somewhere. :-)
Gary Key - Monday, February 27, 2006 - linkItems corrected. Thank you. Wes was up late to get this article posted since my next motherboard review was delayed due to additional testing with a new bios. I deserve the flogging. :) Reply

A9 TV, 29 May 2012
There will be no peace for the world without loving and being close to Allah. People can try if they like, but, may Allah forbid, He will and does ruin them. People are very troubled. The joy has gone out of the world. The economy is flat, the arts are flat, science is flat and suicides are on the rise. Life no longer has any meaning for people. But you are looking for trouble. If, may He forbid, you discount Allah, Who gives you so much beauty and goodness, then of course He will hurt you. Of course He will eliminate all plenty. "Give thanks so I may increase your blessings," says Allah. You just need to give thanks. "I am not grateful," people say. "I will enjoy all those blessings, but I reject You." What kind of morality is that?
Allah creates fruits, cars, houses, technology, televisions and radios, and people still say, "That is no concern of mine. I will make use of them, but their Lord is of no interest to me." So, He will hurt you so that you commit suicide and fall into a terrible depression. If, may Allah forbid, they trouble Almighty Allah, He will trouble them. If they are inimical to Allah, He will crush them. What Allah wants is this; "Be very wise, perfect and scrupuluous. Give thanks to Me. Love Me and I will love you in return." says Allah. This is an exceedingly reasonable, good and fine proposition from Almighty Allah. He says that you will immediately see that your quality of life will improve. Wealth and abundance will follow on immediately.
Look, the economic crisis is ruining Europe; but if they turn to Allah then Europe, America and the Middle East will all be very wealthy indeed. But no, "We are going to trouble Allah," they say. "The economy is stagnant for some reason we fail to comprehend. We do not understand, we must have made a mistake somewhere." It is Allah who causes the economy to stagnate. How can you not see? It is happening before your eyes. The Central Bank, money, dollars and business are all in your hands. How can you not understand? You know perfectly well. Allah is destroying it on metaphysical grounds. That is why everyone must turn to and love Allah before it is too late. There is a great tendency to cruelty and lovelessness in people. Yet love is so delightful. I fail to see why they abandon love.
For my brothers who read the Qur'an, there are subjects that Allah keeps insisting on, and they must attach great importance to these. The Qur'an is not that difficult. People say, "You read and read it, but you can't understand it." That is a falsehood. It is perfectly simple and clear. The text is perfectly comprehensible, but of course we cannot deduce the canonical law from it. We get that from scholars, of course, insha'Allah.
Surat ar-Rahman (verses 1-6)
The All-Merciful taught the Qur'an.
Who teaches it? Allah. It is Allah who teaches scholars and who teaches you. "He created man and taught him clear expression."
Who creates speech? Allah. "The Sun and the Moon both run with precision. The stars and the trees all bow down in prostration."
This is a secret. Plants and trees all bow down in prostration. Trees' roots, their hair, if you will, are all in the ground, aren't they? They stand upside down, masha'Allah.
Allah sent down the Qur'an so that even a shepherd in the mountains could easily understand it. That is how the Qur'an has come down. Allah has not sent it down as a bafflement. The Qur'an is sufficient by itself. People must live by the Qur'an as revealed by our Prophet (saas). It is a simple faith. The Qur'an is not something terribly complicated.
We must be peace-loving. We must not permit oppression. We must be full of love. That is already in us, but we must live by it. Allah creates us to be peace-loving. We dislike violence. Generosity exists in our souls. Giving is most delightful. Then we must forgive. That is also a source of comfort. Not forgiving people troubles one. We must not commit adultery. Adultery darkens the soul. One loses one's sexual power and desire. One has no more desire for woman. That internal energy becomes lost and evaporates. May Allah forbid, man or woman, the darkness of prostitution appears in the face. That darkness persists so long as they persist in it, but when they stop doing it, that darkness goes. The harshness of the prostitute descends on them; be they man or woman. That is very bad. The other way, comes the lightness and sweetness of faith. The Torah says that the flesh of the believer is like the flesh of the lamb. There is a verse about it, too. "Has the time not arrived for the hearts of those who have faith to yield to the remembrance of Allah and to the truth He has sent down, so they are not like those who were given the Book beforefor whom the time seemed over long so that their hearts became hard?Many of them are deviators." says Almighty Allah. Even at the age of 70 they have lovely skin. Men or women, they have a radiance, a lightness. But Allah sends a darkness down on those other dark types. They have very inauspicious looks and facial expressions. But, by Allah's leave, the believer develops that radiance with faith and sincerity.
Surat az-Zumar, 27;
"We have given all kinds of examples to people in this Qur'an,so that hopefully they will pay heed –"
He does not here refer to scholars, but to people in general. Shepherds in the mountains, university professors, adolescents, whoever. Almighty Allah says He has given whatever examples are necessary.
"...an Arabic Qur'an with no distortion in it," says Allah. There is no distortion or inconsistency. "...so that hopefully they will have faith," says Allah.
("NATO forces under U.S. command killed a family of eight in an attack in Afghanistan.")
As if such things were terribly rare. They kill people every day. They slaughter people in towns and villages. They cut fingers off, dry them and send them home. That has already come out in the press. There are thousands of villages in Afghanistan. They go in with tanks. There are soldiers who drink and take drugs, sexual perverts. They kill children and rape women. Afghanistan is a source of terrible pain and suffering. A place of awful suffering. It can only be saved through Islamic Unity.
(About evolutionists' inability to account for the soul)
Evolutionists are not interested in the true person. They leave aside the person who truly sees, the person without eyes. They are only interested in a blind and unseeing system. In the ear that does not hear. No ear hears anything. All ears are deaf. They (the ears) turn sound waves into electric current and transmit it to the brain, that is all. Then their work is done. But there is one there (the soul) who hears with no ears. That is the true person. Evolutionists cannot account for that true person. So they never talk about it.
It is Hazrat Mahdi (pbuh) who will open Hagia Sophia for worship, insha'Allah. I have said this many times. I am now saying it again, insha'Allah. Hazrat Mahdi (pbuh) will perform the first prayer, insha'Allah.
You will either implement Allah's plan or be defeated. There is no other way. Our Prophet (saas) has set Allah's plan out in detail. It is described in detail in the Qur'an, and in the Torah and the Gospel. So long as you insist on avoiding this, there can be no unity, so Muslims will continue to be wretched and to suffer. Terror and pain will enfold the world even more determinedly. That is why I am calling you to the path of Rasulullah (saas), while that path is close. There is no need to prolong matters. Follow the paths set out by Rasulullah (saas). Follow the path he showed through revelation. If you say that is no concern of yours, that means you dislike Allah's commandment, may He forbid. So then you will be of no concern to Allah. Allah will make you miserable and wretched. This is the only way out.
Surah Ghafir, 17; "Every self will be repaid today for what it earned." Everyone will be repaid for what he does. If they have done good, they will receive good. They will earn paradise and Allah's approval. If they have done evil, they will earn hell and the wrath of Allah. "Today there will be no injustice. Allah is swift at reckoning."
Because the result is justice, not oppression. Wrongdoers go to hell. That is justice. The good go to paradise, and that is justice. "Allah is swift at reckoning." The questioning is fast. But for disbelivers and evil-doers the questioning will be very long. Allah will make them feel as if it goes on for a long time.
"And warn them of the Day of Immediacy when hearts rise choking to the throat." The Day of Reckoning. When fear rises to the throat. "...choking to the throat," they will keep having to swallow their regret. "The wrongdoers will have no close friend nor any intercessor who might be heard." There will be no protection for them. They have no friends. Allah says they will be all alone. They will have no friends from the bars, no fathers or grandfathers. Nobody will be interested in them, He says. Everyone will be all alone, He says.
"He knows the eyes' deceit and what people's breasts conceal."
They look with hatred in their eyes and without love. He knows the evil in their hearts and their evil feelings, as well as their good feelings, He says.
Verse 21. "Have they not traveled in the Earth and seen the final fate of those before them?"
What is this? This is archeology. Allah imposes the science of archeology. These subterranean civilizations. You cannot see them without doing research. That only comes about through archeology.2012-08-02 11:19:17

PG&E warns public of metallic balloons creating power outages
Valentine's Day is here and PG&E wants to warn the public that balloons can cause a lot of damage to the power grid.
Many people celebrate with helium-filled balloons. PG&E warns those balloons that contact overhead power lines can disrupt electric service for an entire neighborhood, cause significant property damage and potentially result in serious injuries.
Last year, metallic balloons caused more that 300-outages affecting electric service to nearly one hundred thousand homes in northern and central California and outages from balloons have more than doubled in the past decade. PG&E urges customers to: use caution and avoid celebrating with metallic balloons near overhead electric lines; make sure helium balloons are securely tied and weighted to prevent from floating away; when possible keep indoor and never let them be released outside; do not bundle metallic balloons together and never try to retrieve any type of balloon, kite or toy that becomes caught in a power line. Leave it alone and call PG&E at: 800-743-5000 or visit their on line link: pg&e mylar balloon safety
