■ Encryption-compliant
Self Encrypting Drives (SEDs) are offered for the 2.5" SAS disks.
●
Self Encrypting Drives (SEDs)
Each SED has an encryption function.
Authentication keys are required to access SEDs. There are two types of SED authentication keys; an
authentication key (a common key that is shared by all of the SEDs) that is created in the ETERNUS DX Disk
storage system and an authentication key that is created in the key server.
- Only one key can be registered in each ETERNUS DX Disk storage system. This common key is used for
all of the SEDs that are installed. Once the key is registered, the key cannot be changed or deleted. The
common key is used to authenticate RAID groups when key management server linkage is not used.
- To use the authentication key in a key server, a key group needs to be created. Multiple RAID groups
can be registered in a key group. Note that only one key group can be created in each ETERNUS DX Disk
storage system. Only one authentication key can be specified for each key group. The authentication
key for a key group can be changed.
For details, refer to
• When using SEDs, the firmware version of the ETERNUS DX Disk storage system must be V10L20 or
later. If the firmware version is earlier than V10L20, SED access performance may be reduced.
• When using the key management server linkage function, the firmware version of the ETERNUS DX
Disk storage system must be V10L46 or later.
• The firmware version can be checked via ETERNUS Web GUI or ETERNUS CLI. When upgrading
firmware is required, contact your sales representative.
