[0] Forklift Upgrades; Cost Effective Scalability No Forklift Upgrades; Cost Effective to Scale Uses full servers. As data grows you add another server into a GRID architecture. Each server comes with processor, memory, bandwidth and disk. When your data goes from 10TB to 40TB, you simply keep adding more appliances and the system keeps growing. There are no forklift upgrade points and no future costs to consider. Just add as you grow.
Forklift Upgrades; Costly to Scale Only disk is added as data grows, but at some point the front-end server can no longer keep up because the amount of disk you can add behind fixed processor, memory and bandwidth is limited. At some point the front-end server must be replaced with a server with faster processor and memory, which is a “forklift” upgrade. Some product lines have as many as five forklift upgrade points. Since the cost of the front-end can be as much as the price of the initial system, when you buy in and then hit a forklift upgrade point, you may have to spend about as much for the upgrade as what you originally spent.
