ServeRAID M1115 SAS/SATA Controller for IBM System x
4
The following features are optional and require the purchase of an additional upgrade:
RAID 5, 50 support with Zero Cache/RAID 5 Upgrade (81Y4542)
MegaRAID SafeStore support for self-encrypting drive (SED) services
MegaRAID SafeStore encryption services offer instant secure erase and local key management for
self-encrypting 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 feature removes the
complexity of managing each SED’s unique encryption key, and essentially, it relieves the
administrator of most of the daily tasks of securing data. The SafeStore feature is a part of a RAID 5
upgrade (81Y4542).
