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

You can create a VSA cluster with two or three ESXi hosts. The hosts that you add to the cluster can have newly installed ESXi. You can also use existing hosts that have virtual machines running on their local datastores. 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.


If you plan to use a single vCenter Server to manage multiple VSA clusters, create a separate datacenter object for each VSA cluster.


Create a new datacenter.


In vSphere Client, select File > New > Datacenter.

A new datacenter object appears in the inventory.


Enter a name for the datacenter and press Enter.


Add hosts to the new datacenter.


Select the datacenter in the inventory.


Select File > New > Add Host.


On the Connection Settings page of the Add Host Wizard, enter the IP address and root credentials of the ESXi host to add and click Next.


On the Host Summary page, review the information about the host and click Next.


On the Assign License page, select Assign a new license key to this host radio button if your ESXi host does not have an assigned license, and assign a new license.


Click Next.


On the Virtual Machine Location page, select the datacenter you created and click Next.


On the Ready to Complete page, review your selections and click Finish.


Repeat steps from a to h to add another ESXi host.

You can now create the VSA cluster by running the VSA Installer wizard.
