Encryption Authorization
The Encryption Authorization feature provides data encryption by using IBM® Full Disk Encryption (FDE) and key managers, such as IBM Security Guardium Key Lifecycle Manager.
The Encryption Authorization feature secures data at rest and offers a simple,
cost-effective solution for securely erasing any disk drive that is being retired or re-purposed
(cryptographic erasure). The storage system uses disks that have FDE encryption hardware and can
perform symmetric encryption and decryption of data at full disk speed with no impact on
performance.
Note: The Encryption Authorization feature is part of the Base
Function license and is only available for certain countries.
