Processor and Memory Utilization
This section discusses the processor and memory utilization in all the three scenarios. The processor
utilization was targeted at less than 75% at all times as a design validation requirement. This ensures
that all processes within the server are being executed in a timely fashion.
Memory plays an important role in your Exchange 2010 deployment as pages can be fetched faster
without having to go to disk. The total memory made available to each of the servers was 48 GB. Since
the memory manager in Exchange is designed to use as much physical memory as available, the Memory
Utilization is at approximately 36 GB, about 16 GB higher than the recommended 20 GB. Exchange 2010
collects pages to be written in memory and then performs fewer write operations to disk periodically,
thereby minimizing disk activity. For production deployments, the initial calculation of 20GB per server
should be sufficient. In our lab runs, 48 GB was available and was used. Figure 17 and Figure 18 show
the Processor and Memory utilization during the tests for all three scenarios.
