In MiniCluster, data protection at rest is automatically configured using ZFS data set encryption. The encryption is configured as follows:
All ZFS data sets are encrypted in virtual machines (VMs), including the root and swap file systems.
All ZFS data sets re encrypted in the global zone, with the exception of the root and swap file systems.
You can verify the encryption configuration by viewing the encryption keys. See View ZFS Data Set Encryption Keys (BUI).
