The Software RAID On Mother Board (ROMB) solution offers a wide selection of
features for managing your RAID system. This chapter provides an explanation
of RAID concepts and how to take advantage of the Software ROMB features.
Introduction to RAID
RAID (Redundant Array of Independent Disks) allows multiple hard drives to be
combined together into a logical drive. The operating system sees the logical
drive as a single storage device, and treats it as such. The RAID software and/or
controller handle all of the individual drives on its own. The benefits of a RAID
can include:
Higher data transfer rates for increased server performance
Increased overall storage capacity for a single drive designation (such as, C,
D, E, etc.)
Data redundancy/fault tolerance for ensuring continuous system operation in
the event of a hard drive failure
Different types of logical drives use different organizational models and have
varying benefits. The following outline breaks down the properties for each type
of RAID logical drive.
