Single controller multipathing (failover) I/O load balancing
The ServeRAID's firmware detects and uses multiple paths from the controllers to the SAS drives that
are in enclosures. With redundant paths to the same port of a device, if one path fails, another path
can be used to communicate between the controller and the drive. Using multiple paths with load
balancing, instead of a single path, can increase reliability through redundancy.

WebBIOS configuration utility for pre-boot array configuration and management
WebBIOS 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 levels 6 and 60 with M5100 Series RAID 6 Upgrade (81Y4546)
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 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 part of any RAID 5 upgrade that is available: 81Y4544, 81Y4484,
81Y4487, or 81Y4559.

MegaRAID CacheVault flash cache protection
MegaRAID 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 RAID controller,
CacheVault technology transfers the contents of the NAND flash back to the DRAM, which will
eventually be flushed to disk.

MegaRAID FastPath SSD performance acceleration
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 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 M5100 Series Performance Accelerator (90Y4273).
