Make sure that the ESXi hosts meet the software requirements to join a VSA cluster.

Table 1. ESXi Software Configuration Requirements for a VSA Cluster

Configuration

VSA Cluster Requirements

ESXi version

Each host must have a version of ESXi compatible with the latest version of VSA installed. For information, see the VMware Product Interoperability Matrix at http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.

ESXi license

For trial installations of the VSA cluster, you can run ESXi in evaluation mode.

For licensed installations, the license model you use depends on whether you plan to manage a single VSA cluster or multiple clusters.

Cluster configuration

None of the ESXi hosts must participate in another cluster.

vSphere standard switch and port group configuration

If you use newly installed ESXi hosts for your cluster, standard vSwitches and port groups are created during the VSA cluster installation. If you use existing hosts that have preconfigured vSwitches, the VSA cluster installer audits the vSwitches.

Note:

Make sure that the name of the VMkernel port group is Management Network. VSA Manager uses this name to retrieve host network information.

IP address

Each ESXi host must be assigned a unique static IP address. Do not change the IP address of any of the hosts that form the VSA cluster. Otherwise you might break the VSA cluster.

Note:

vCenter Server and the VSA cluster can be on different subnets.

Virtual machines

VSA supports creating a VSA cluster on ESXi hosts that have running virtual machines. After you create the cluster, move the virtual machines that reside on the hosts' local VMFS datastores to the VSA datastores.
