You can create a cluster, and then configure the cluster for vSAN.
- Right-click a data center and select New Cluster.
- Type a name for the cluster in the Name text box.
- Turn on DRS, vSphere HA, and vSAN for the cluster.
- Click OK.
The cluster appears in the inventory.
- Add hosts to the vSAN cluster.
vSAN clusters can include hosts with or without capacity devices. For best results, add hosts with capacity.
