Scenario 3: SQL Server Consolidation Using Cisco UCS B440 M2 With 100 GB Database
As described in workload section, we started test with one large database in the SQL Server Instance running on
the virtual machine. We captured the test results at the end of test. Later we keep on adding one virtual machine at
a time with the same memory and database instance. At every virtual machine count we captured metrics of the
workload. It was observed that the best utilization of CPU and Memory of each virtual machine as well as Physical
machine was sustained until 7 virtual machines were deployed on the same physical machine.
Figure 26 shows the resource Utilization of Cisco UCS B440 M2, especially CPU and memory of physical machine
after adding each virtual machine one after another with one large database in each virtual machine and
concurrently running OLTP workload one each virtual machine. Workload was capped to make sure that resources
(Memory and CPU) were not saturated. In this testing process we observed 86 percent of memory utilization and
74 percent CPU Utilization. As it is shown in the graph, physical machine still had enough CPU and memory to
handle any unexpected spikes in the workloads.
