Within the table titled To: (Selected VM Host), select a destination VM host for the previously
selected systems.
Server presentation:
The table entries are ordered by headroom fitness as determined by Capacity Advisor, and
Capacity Advisor selects the top selection by default. Examine the headroom rating and the
utilization meters for each prospective host to determine which host best fits your goals for
headroom fitness and optimal utilization. (See
for a discussion of this
concept.)
9.
Click OK to accept these changes.
Unknowingly accepting unseen values:
This can happen if you modify the CPU virtualization overhead % or headroom calculation
after selecting the destination server, but then click OK without refreshing the destination table
with the new values. The resulting change to the utilization values shown in the System tab
view will differ from those seen in the previously shown destination table because the System
tab will reflect the modified values.
When modifying CPU virtualization overhead % or headroom, remember to click Refresh,
and check the updated values shown in the utilization meters in the destination table. Once
you have refreshed this table, select a server based on the new values. If you want the same
server that you selected before changing the values, you must re-select that server to enable
the OK button.
After clicking OK, you see an updated Edit Scenario page. The modified system(s) now appear
with the VM guest type listed under System Type (for example, 'Integrity VM'). Additionally, the
modified system(s) is/are listed under the selected destination server.

Assigning VM hosts to a VMware DRS cluster in a scenario
You can use Capacity Advisor to simulate the behavior of workloads and VMs that are members
of a VMware Distributed Resource Scheduler (DRS) cluster. This conversion is meant to let you
simulate VM hosts running VMware ESX servers. Once you have created one of these “what-if”
cluster scenarios, you are able to do any of the following actions in this scenario:
•
Add other VM hosts to the cluster
•
Consolidate or load balance VMs in a cluster
In addition, you can run reports on clusters defined within a scenario.
Initially converting VM hosts to simulate a VMware DRS cluster
1.
From the System tab of the scenario editor, click the check boxes for two or more ESX VM
hosts that you want to convert to a DRS cluster.
IMPORTANT:
If you want to see power metrics for the cluster, make sure that all VM hosts
that you select have been calibrated (either automatically or manually) before adding them
to a cluster.

Select What-If Action
→Convert/Add to VMware DRS Cluster....
The Convert/Add to VMware DRS Cluster screen opens.
