After you obtain an appropriate license key, assign it to your Virtual SAN cluster. Alternatively, you can use an existing Virtual SAN license key if one is available in the inventory of the vCenter Server system.

When you enable Virtual SAN for a cluster, you can use Virtual SAN in evaluation mode to explore its features. The evaluation period starts when Virtual SAN is enabled and expires after 60 days. To use Virtual SAN, you must license the cluster before the evaluation period expires. For more information, see the License Management and Reporting section of the vCenter Server and Host Management Guide.
