Encryption Restrictions

This section describes encryption restrictions for disks on the Dell XC Series Hyper-Converged Appliance.

  • If encryption has never been enabled and you do not plan to use it in the future, secure encrypted drives (SED) can be mixed with unencrypted (non-SED) drives in the same node.
  • If encryption was never enabled and remains disabled, encrypted nodes can be mixed with unencrypted nodes in the same cluster.
  • Encryption is not supported for NVMe drives.
  • All nodes in the cluster must have SED capable drives to use Data at Rest encryption.
NOTE: If SED drives are mixed with non-SED drives, the encryption cannot be enabled for that cluster.

An encryption key must be removed from the SED drives from Prism before you format (clear) the SED drives.

A key server is required for Data at Rest Encrpytion in a cluster.
