Create an EVC cluster to help ensure vMotion compatibility between the hosts in the cluster.

When you create an EVC cluster, use one of the following methods:

Create an empty cluster, enable EVC, and move hosts into the cluster.

Enable EVC on an existing cluster.

VMware recommends creating an empty EVC cluster as the simplest way of creating an EVC cluster with minimal disruption to your existing infrastructure.

Before you create an EVC cluster, ensure that the hosts you intend to add to the cluster meet the requirements listed in EVC Requirements.

1

Create an empty cluster, and enable EVC.

Select the CPU vendor and EVC mode appropriate for the hosts you intend to add to the cluster. For information on configuring EVC, see the vSphere Client online Help.

Other cluster features such as VMware DRS and VMware HA are fully compatible with EVC. You can enable these features when you create the cluster. For information on specific cluster options, see the vSphere Client online Help.

2

Select a host to move into the cluster.

3

If the host feature set is greater than the EVC mode that you have enabled for the EVC cluster, ensure that the cluster has no powered-on virtual machines.

Power off all the virtual machines on the host.

Migrate the host’s virtual machines to another host using vMotion.

4

Move the host into the cluster.

You can power on the virtual machines on the host, or migrate virtual machines into the cluster with vMotion, if the virtual machines meet CPU compatibility requirements for the cluster’s EVC mode. Virtual machines running on hosts with more features than the EVC mode must be powered off before migration into the cluster.

5

Repeat Step 3 and Step 4 for each additional host that you want to move into the cluster.
