Figure 7: Detailed results for the legacy server and the Dell PowerEdge T630 with 200-user workloads.
Figure 8 shows the median runs for the memory and SSD upgrade steps. For each step and user count we tested,
we used the following pass/fail requirements:
 Exchange latency needed to remain under 100ms
 SharePoint latency needed to remain under 1s
 File server IOPS needed to be at a minimum of 0.3 IOPS per user (60 IOPS for 200 users, 90 IOPS for 300, and
120 IOPS for 400)
 Each SQL database instance had to be above 14,000 OPM
