Experimentation
You can better understand Capacity Advisor by experimenting — considering different configurations
and workload placement trying them out in “what-if” scenarios. A scenario identifies the workload
demand profile that creates your experimental simulations.
When you do workload analysis in Capacity Advisor, you view graphs and reports that represent
CPU or memory utilization by time. For example,
Figure 2 shows a graph of CPU utilization for a
single system over a one-month period.
Figure 2 CPU utilization for managed system puny03v8
1 Peak (highest) value.
Similarly, Figure 3 shows CPU utilization for a second system over the same period.
Figure 3 CPU utilization for managed system puny03v7
1 Peak value.
Comparing these two graphs shows that workload peaks on the two systems do not occur
simultaneously, nor do they require the same percentage of the allocated CPU cores for processing.
This suggests an opportunity to consider whether you can consolidate both systems together to
satisfy the needs of the workloads, while reducing the number of CPU cores (originally each system
is allocated 2 cores, for a total of 4 cores available to do work).
Figure 4 shows the result of using a Capacity Advisor “what-if” scenario to combine the workloads
onto one system.
