Dell PowerEdge RAID Controller 11 User’s Guide PERC H755, H750, H355, and H350 Controller Series

Self-Encrypting Disks

Select PERC 11 cards support self-encrypting disks (SEDs) for protection of data against loss or theft of SEDs. For information about cards supported, see Technical specifications. Protection is achieved by the use of encryption technology on the drives. There is one security key per controller. You can manage the security key using local key management (LKM) or OpenManage Secure Enterprise Key Manager also referred as Secure Enterprise Key Manager (SEKM). The controller use the security key to lock and unlock access to encryption-capable physical disks. To take advantage of this feature, you must:
  • Have SEDs in your system, and
  • Create a security key.

PERC cannot use SEDs that are secured by a non-PERC entity. Ensure that the SED is reprovisioned in an applicable manner by that non-PERC entity before connecting to PERC.

For more information, see the Security key and RAID management section.

NOTE:You cannot enable security on non-optimal virtual disks.
NOTE:PERC 11 supports Trusted Computing Group Enterprise (TCG) Security Subsystem Classes (SSC) SAS or SATA SED drives and TCG Opal SSC NVMe drives.
