You can edit the settings of your vSAN cluster to configure data management features and enable services provided by the cluster.

Edit the settings of an existing vSAN cluster if you want to enable deduplication and compression, or to enable encryption. If you enable deduplication and compression, or if you enable encryption, the on-disk format of the cluster is automatically upgraded to the latest version.
