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 (HDD) to be handled collectively.
In actual, RAID can configure more than one HDDs as a single array (disk group) to
operate the HDDs effectively. This can bring higher performance than a single HDD of
a large capacity.
The Onboard RAID Controller (LSI Embedded MegaRAID) or Internal RAID
Controller has a feature to divide a single disk group into several virtual 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 the
Rebuild feature if an error occurs in a single HDD. This can provide high reliability for
the system.
