ServeRAID M5210 and M5210e SAS/SATA Controllers for IBM System x 4
Global and dedicated hot spare with revertible hot spare support
A hot spare rebuilds data from all virtual disks within the disk group in which it is configured.
ServeRAID can define a physical disk as a hot spare to replace a failed drive. Hot spares can be
configured as either global or dedicated. A global hot spare allows any physical drive to be
designated as a hot spare. A dedicated hot spare allows the user to assign a hot spare drive to a
particular array of the same drive type.
Drive roaming
Drive roaming occurs when the physical disks are changed to different ports on the same controller.
When the drives are placed on different channels, the controller detects the RAID configuration from
the configuration data on the drives.
Human Interface Infrastructure (HII) configuration utility for pre-boot array configuration and
management
HII is a utility that is built into the ServeRAID controller that allows you to configure drive groups and
logical drives before installing or booting the operating system.
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.
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)
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).
