IBM 90Y4304 Manuale Utente
ServeRAID M5016 SAS/SATA Controller
5
Support for RAID levels 6 and 60 and self-encrypting drives as a standard feature (no additional
feature keys required)
LSI SafeStore support for self-encrypting drive services
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 of most of the daily tasks of securing
data.

CacheVault flash cache protection
LSI CacheVault flash cache protection uses NAND flash memory powered by a supercapacitor to
protect data stored in the controller cache. This module eliminates the need for a lithium-ion battery
commonly used to protect DRAM cache memory on PCI RAID controllers. To avoid the possibility of
data loss or corruption during a power or server failure, CacheVault technology transfers the contents
of the DRAM cache to NAND flash (CacheVault flash module - CVFM) using power from the
CacheVault power module (CVPM). After the power is restored to the M5016 RAID controller,
CacheVault technology transfers the contents of the NAND flash back to the DRAM, which will
eventually be flushed to disk.
