ServeRAID M5025 SAS/SATA Controller for IBM System x 4
The ServeRAID M5000 Series Advanced Feature Key enables the following features:
RAID levels 6 and 60

LSI SafeStore: support for self-encrypting drive services:

Instant secure erase

Local key management

LSI SafeStore encryption services offer instant secure erase and local key management for
self-encrypting drives. This technology represents a significant step forward in securing data on a disk
drive from any unauthorized access or modification resulting from theft, loss, or repurposing of drives:
Instant secure erase permanently removes data when repurposing or decommissioning SEDs.

SafeStore local key management provides the necessary management and protection of SEDs using

a simple pass phrase, security key identifier, and security key file that can be set and applied to all
SEDs assigned to a ServeRAID adapter. This removes the complexity of managing each SED’s
unique encryption key, and essentially relieves the administrator from most of the daily tasks of
securing data.
Note: To use the SED services of the ServeRAID M5000 Series Advanced Feature Key, you must use
self-encrypting drives as listed in "Supported disk drives" below.
Self-encrypting drives are based on a new technology that helps prevent data from being accessed
without authorization. These drives adhere to the Trusted Computing Group (TCG) Enterprise Security
Subsystem Class specification and are National Security Agency qualified to provide government-grade
encryption. With self-encrypting drives (SEDs), if a drive is removed from its storage system or the server
that it is housed in, the data on that drive is encrypted and useless to anyone who attempts to access it
without the appropriate security authorization.
