Dell Unity supports 2-way NDMP for File data, which allows the system to send File data directly to a backup device using FC connections.
Note that NDMP must use different ports than the FC ports which are designated for Synchronous Replication. This is true even if Synchronous Replication is not actively being used.
To lessen the impact of 2-way NDMP backups on other host activity, consider reducing the number of host connections on the FC ports used for NDMP.
Data At Rest Encryption (D@RE)
D@RE is Controller Based Encryption that does not impact performance; therefore, Dell Technologies recommends ordering Dell Unity systems as encryption-enabled, if appropriate for your environment.
Note that encryption can only be enabled at the time of system installation with the appropriate license. If encryption is enabled, Dell Technologies recommends making external backups of the encryption keys after system installation, and immediately following any change in the system’s drives (such as creating or expanding a storage pool, adding new drives, replacing a faulted drive, and more).
