Data at rest encryption encrypts user data by using software within the storage system. Data at rest encryption is disabled by default. Data at rest encryption can be enabled only when you select BYOL at the time of storage cluster configuration. When you enable Data at rest encryption, do so before expanding a storage pool.
Details about how to enable Data at rest encryption, see Using Data at rest encryption in the VSP One SDS Block System Administrator Operation Guide.
