MegaRAID Storage Manager management software
MegaRAID Storage Manager is an easy-to-use advanced RAID management application that is
used across the entire family of ServeRAID M controllers. It allows you to configure, monitor, and
maintain drive groups, virtual drives, and advanced features with an intuitive GUI, reducing
administrative efforts and simplifying troubleshooting.
Note: RAID 10, 50 and 60 drive groups do not support Online Capacity Expansion and Online RAID Level
Migration. RAID 0, 1, 5, and 6 drive groups do not support Online Capacity Expansion and Online RAID
Level Migration if two or more virtual drives are defined on a single drive group.
The following features are optional and require the respective upgrade to be purchased:
Support for RAID 6 and 60 with M5200 Series RAID 6 Upgrade (47C8706)
This is a Features on Demand upgrade and one upgrade is needed per server; all M5200 and
M5100 series adapters installed in the server will have this upgrade enabled automatically.
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 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 by
using a simple pass phrase, security key identifier, and security key file that can be set and applied
to all SEDs that are assigned to a ServeRAID adapter. This feature removes the complexity of
managing each SED’s unique encryption key, and it essentially relieves the administrator of most of
the daily tasks of securing data. The SafeStore is a part of any M5200 Series RAID 5 upgrade that is
available: 47C8708, 47C8656, 47C8660, 47C8664, or 47C8668.
MegaRAID flash cache protection
MegaRAID flash cache protection uses NAND flash memory, which is powered by a
supercapacitor, to protect data that is stored in the controller cache. This module eliminates the
need for a lithium-ion battery, which is 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 offload power module. After the power is restored to the RAID controller, the
content of the NAND flash is transferred back to the DRAM, which is flushed to disk.
MegaRAID FastPath SSD performance acceleration
MegaRAID FastPath software provides high-performance I/O acceleration for SSD-based virtual
drives by using a low latency I/O path to increase the maximum I/O per second (IOPS) capability of
the controller. This feature boosts the performance of applications with a highly random data
storage access pattern, such as transactional databases. The feature is activated by enabling
M5200 Series Performance Accelerator (47C8710).
This is a Features on Demand upgrade and only one upgrade is needed per server; all M5200 and
M5100 series adapters installed in the server will have this upgrade enabled automatically.
MegaRAID CacheCade SSD caching for traditional hard disk drives
MegaRAID CacheCade read/write software accelerates 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 the I/O
performance for transaction-intensive applications, such as databases and web serving.
CacheCade software tracks data storage access patterns and identifies the most frequently
accessed data. The hot data is then automatically stored on the solid-state storage devices that are
assigned as a dedicated cache pool on a ServeRAID controller with the M5200 Series SSD Caching
feature (47C8712) enabled.
This is a Features on Demand upgrade and only one upgrade is needed per server; all M5200 and
M5100 series adapters installed in the server will have this upgrade enabled automatically.
