RAID
Overview of RAID System
What is RAID (Redundant Array of Inexpensive Disks)?
RAID is an abbreviation for "Redundant Array of Inexpensive Disks". The RAID technology allows
more than one hard disk drive to be handled collectively.
In actual, RAID can configure more than one hard disk drives as a single array (disk group) to
operate the hard disk drives effectively. This can bring higher performance than a single hard disk
drive of a large capacity.
The Onboard RAID Controller (LSI Embedded MegaRAID
) or optional RAID Controller has a
feature to divide a single disk group into several logical drives (virtual disks). The RAID Controller
recognizes these virtual disks as if it were a single hard disk drive. The RAID Controller accesses to
more than one hard disk drive configuring a disk group in parallel.
Some RAID levels can recover data from remaining data and parity by using rebuild feature if an
error occurs in a single hard disk drive. This can provide high reliability for the system.
