If you already have vCenter Server 5.0 installed, you can use the VSA Installer wizard to create the VSA cluster manually.

The VSA Installer wizard provides a graphical workflow to installing the VSA cluster. You use the wizard to accomplish a set of tasks.

1

Select a datacenter object for the VSA cluster

2

Select which hosts to include in the VSA cluster

3

Configure the network of the VSA cluster

4

Choose when to format the disks of the VSA cluster

After you complete the steps in the wizard, the VSA Installer performs a set of tasks that create the VSA cluster.

1

Configures the network of each ESXi host.

The installer creates a front-end and a back-end virtual switch on each ESXi instance to support the front-end and back-end networks of the cluster. The installer selects two uplink ports for each virtual switch from the four available NIC ports. As a result, each virtual switch has one primary and one redundant uplink.

2

Deploys a vSphere Storage Appliance on each ESXi host.

3

Configures each vSphere Storage Appliance to export one half of the ESXi storage space as a VSA datastore, and the other half as a replica of another VSA datastore.

VSA 0 exports VSA datastore 0 and maintains a replica of VSA datastore 2.

VSA 1 exports VSA datastore 1 and maintains a replica of VSA datastore 0.

VSA 2 exports VSA datastore 2 and maintains a replica of VSA datastore 1.

4

Configures the network interfaces on each vSphere Storage Appliance to establish the front-end and back-end networks of the VSA cluster.

The VSA cluster members form the VSA cluster by establishing a process of electing a cluster leader. The cluster leader is the VSA cluster member that communicates with VSA Manager to report the status of the VSA cluster.
