Before you create a VSA cluster, you must create a datacenter and add newly installed ESXi hosts in vCenter Server.

You can create a VSA cluster with two or three ESXi hosts. The number of available datastores in the VSA cluster equals the number of hosts that you add to it. Creating a cluster with three hosts makes the cluster more reliable and provides more datastore space.

You can skip this procedure, if you use the VSA Automated Installer.
