what is a vsa cluster
What Is a VSA Cluster? A VSA cluster leverages the computing and storage resources of several ESXi hosts and provides a set of datastores that are accessible by all hosts within the datacenter. An ESXi host that runs a vSphere Storage Appliance and participates in a VSA cluster is a VSA cluster member. With vSphere Storage Appliance 1.0, you can create a VSA cluster with two or three VSA cluster members. The status of the VSA cluster is online only when more than half of the members are online.
