  +This section provides VMware-recommended NUMA, CPU, and BIOS settings for your hardware and virtual machines.
   
   -   Always enable hyper-threading, and do not overcommit CPU.
   -   For most production <%=vars.product_name_long%> servers, always use virtual machines with at least two vCPUs .

      If you restart the ESXi host, the above configuration must be reapplied.
  
      **Note:**
      Disabling interrupt coalescing can reduce latency in virtual machines; however, it can impact performance and cause higher CPU utilization. It can also defeat the benefits of Large Receive Offloads (LRO) because some physical NICs (such as Intel 10GbE NICs) automatically disable LRO when interrupt coalescing is disabled. See [http://kb.vmware.com/kb/1027511](http://kb.vmware.com/kb/1027511) for more details.
  
  -   **Virtual NIC:** Use the following guidelines when configuring your virtual NICs:
      -   Use VMXNET3 virtual NICs for your latency-sensitive or otherwise performance-critical virtual machines. See [http://kb.vmware.com/kb/1001805](http://kb.vmware.com/kb/1001805) for details on selecting the appropriate type of virtual NIC for your virtual machine.

  This topic discusses use limitations of vSphere vMotion, including its use with DRS.
  
  When vMotion migrations occur, there is an expected temporary drop in the performance of both read-operation and write-operation workloads.
  These workloads resume their normal rate of operation once the vMotion migration of the servers is completed.
  
  VMware recommends that all vMotion migration activity of <%=vars.product_name_long%> members occurs over 10GbE, during periods of low activity and scheduled maintenance windows.
  Test vMotion migrations in your own environment to assess differences in workload, networking, and scale.
  
  If you wish to prevent automatic VMware vSphere vMotion® operations that can affect response times, place VMware vSphere Distributed Resource Scheduler™ (DRS) in manual mode when you first commission the data management system.
