The RAID Manager uses drive groups. A drive group is a set of drives that have been configured into one or more LUNs. Each LUN is uniquely identified.

The operating system recognizes a LUN as a disk and is not aware that it is actually writing to spaces on multiple disk drives. This technique allows RAID technology to provide data availability without affecting the operating system.
