Key Measures

You need to measure CPU and memory requirements on a per client basis. You then need to scale that by the number of clients. A rule of thumb is each MES client will require about 150 MB of RAM.

The CPU on a Terminal Server machine is typically used more than on other servers. This is desired as you want to utilize the resource fully. You need to check peak demand time (such as at shift changes) to ensure that there is sufficient free capacity and, if a redundant pair is being used, that CPU usages never exceeds 50%. As a starting point on a new system, plan for 12 clients per CPU.

• For redundant pair: CPU usage < 50%

• For standalone: CPU usage < 80%

• Memory should be stable with 1 GB free
