About this task

After enabling Virtual SAN on your cluster, you cannot move Virtual SAN hosts from a Virtual SAN enabled cluster to a non-Virtual SAN cluster.

Procedure

  1. Navigate to an existing host cluster in the vSphere Web Client.
  2. Click the Configure tab.
  3. Under vSAN, select General and click Edit to edit the cluster settings.
  4. If you want to enable deduplication and compression on the cluster, select the Deduplication and compression check box.

    Virtual SAN automatically upgrades the on-disk format, causing a rolling reformat of every disk group in the cluster.

  5. (Optional) If you want to enable encryption on the cluster, select theEncryption check box, and select a KMS server.

    Virtual SAN automatically upgrades the on-disk format, causing a rolling reformat of every disk group in the cluster.
