3 Configure a policy to consolidate and balance workloads on your clusters, and apply that policy to the
custom group.
You configure a policy in vRealize Operations Manager to establish the settings for consolidation,
balance, fill, CPU, memory, and disk space. For example, you modify the setting named Consolidate
Workloads to determine the best placement for new managed workloads based on the cluster status
and capacity. You also modify the threshold setting for Balance Workloads to the level of
aggressiveness required to place workloads. You can configure one or more policies, and apply them
to your cluster compute resources.
a To locate the policies, click Administration > Policies > Policy Library .
b To set workload values, click Add/Edit Policy, and click Workload Automation.
The settings named Consolidate Workloads and Cluster Headroom apply to the initial placement
of virtual machines.
n
When you set Consolidate Workloads to none, workload placement balances the workload
across all the clusters to which the policy is applied. When you set Consolidate Workloads to
a value other than none, workload placement fills the busiest cluster first.
n
Cluster Headroom is the buffer space reserved in a cluster, as a percentage of the total
capacity. For example, if you set the cluster headroom to 20%, that buffer might prevent
workload placement from placing virtual machines on that cluster. The reason it prevents the
placement is because the cluster has 20% less of the free capacity for CPU, memory, or disk
space.
c In the policy workspace, click Apply Policy to Groups.
d Select the custom group.
e Save the policy.
You configured vRealize Operations Manager so that vRealize Automation uses the workload placement
analytics to suggest placement destinations of machines when users deploy blueprints.
What to do next
Wait for vRealize Automation and vRealize Operations Manager to collect data from the endpoints and
objects in your environment. Then, when you deploy new blueprints, vRealize Automation displays the
workload placement recommendations, destination candidates, and selected placement for your
confirmation.

If you experience problems with workload placement, use the troubleshooting information to resolve
them.
