D@RE is a powerful solution for securing and protecting data that resides at rest on PowerMax systems. The data security provided by encryption is only as good as the generation, protection, and management of the keys used in the encryption process. PowerMax 2500/8500 systems use SEDs, which are self-encrypting and contain their own data encryption keys (DEKs) that are managed internally within the drives. Since the keys on SEDs are self-managed, D@RE key management infrastructure generates and manages authentication keys (AKs), which are used to unlock the drives for reads and writes to the media.
