After you enable Virtual SAN, a single datastore is created. You can review the capacity of the Virtual SAN datastore.
Activate Virtual SAN and configure disk groups.
- Browse to Datastores in the vSphere Web Client navigator.
- Select the Virtual SAN datastore.
- Click the Manage tab, and click Settings.
- Review the Virtual SAN datastore capacity.
The size of the Virtual SAN datastore depends on the number of HDDs per ESXi host and the number of ESXi hosts in the cluster. For example, if a host has seven 2TB HDDs, and the cluster includes eight hosts, the approximate storage capacity would be 7 x 2 TB x 8 = 112TB. Some capacity is allocated for metadata.
What to do next
Use the storage capabilities of the Virtual SAN datastore to create a storage policy for virtual machines. For information, see About Virtual Machine Storage Policies.
