HP Matrix Operating Environment Software - Manual (Page 138)

The application on legacy03 has a two-core processing capacity. A significant gap exists between
Average use (.35 cores) and Peak use (1.63 cores), as can be seen in the Interval Metric Summary.
Comparing CPU core usage at the 90th Percentile (90% of usage measures fall below this value
– 0.69 cores) with the Peak usage (1.63 cores), you can see that almost one core is required to
support 10 percent of CPU use on this server.
Adding a VM host to the scenario
As of yet, this scenario does not include a VM host on which the virtual machines can be put once
you create them. Click Edit
→Add Existing Systems... on the System tab.
A list of discovered systems displays on the Systems screen. Select two or three VM hosts that
seem likely to be able to host the additional VMs. Click OK to include them in the scenario.
The System tab screen now displays the VM hosts in addition to the initially selected systems:
NOTE: This example has been intentionally constructed to exercise a number of Capacity Advisor
screens. Careful study of the utilization meters on the System tab can help you anticipate changes
that you will need to make in resource provision or allocation before you try to consolidate systems.

Making servers become virtual machines
Select the check boxes for servers that are to become virtual machines, and then select What-If
Action
→Change Servers to be VMs→Manually Change Servers to be VMs...
For this example, 10 legacy servers were selected – four of which exceeded utilization limits
assumed by Capacity Advisor.
The Manually Change Servers to be VMs... screen opens, and by scrolling down, you can see an
evaluation of the current fitness of the selected VM hosts in relation to the proposed addition of
the legacy servers:
