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. 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.
The SafeStore is a part of any RAID 5 upgrade available: 81Y4484, 81Y4487, 81Y4559, or 47C8670.
MegaRAID flash cache protection
MegaRAID 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, flash cache protection technology
transfers the contents of the DRAM cache to NAND flash using power from the flash power module.
After the power is restored to the RAID controller, flash protection technology transfers the contents
of the NAND flash back to the DRAM, which will eventually be flushed to disk.
MegaRAID FastPath SSD performance acceleration
This feature is activated by enabling M5100 Series Performance Accelerator upgrade (90Y4273).
MegaRAID FastPath software provides high-performance I/O acceleration for SSD-based virtual
drives by exploiting an extremely low latency I/O path to increase the maximum IOPS capability of
the controller. This feature boosts performance of applications with highly random data storage
access patterns like transactional databases.
M5100 Series Performance Accelerator is a Features on Demand upgrade and one upgrade is
needed per server; all M5100 and M5200 series adapters installed in the server will have this
upgrade enabled automatically.
MegaRAID CacheCade SSD caching for traditional hard drives
This feature is activated by enabling M5100 Series SSD Caching Enabler upgrade (90Y4318).
MegaRAID CacheCade read/write software is designed to accelerate the performance of hard disk
drive (HDD) arrays with only an incremental investment in solid state drive (SSD) technology. The
software enables SSDs to be configured as a dedicated pool of controller cache to help maximize
I/O performance for transaction-intensive applications like databases and web serving. CacheCade
software tracks data storage access patterns and identifies the most frequently accessed data. This
hot data is then automatically stored on the solid state storage devices assigned as a dedicated
cache pool on a ServeRAID controller.
M5100 Series SSD Caching Enabler is a Features on Demand upgrade and one upgrade is needed
per server; all M5100 and M5200 series adapters installed in the server will have this upgrade
enabled automatically.
