This section describes the configuration utility "WebBIOS". With On Board RAID (MegaRAID
ROMB), you can use the internal hard disk drives in the disk array configuration.
RAID
This section describes the RAID features which the on-board RAID controller (MegaRAID ROMB)
supports.
Overview of RAID
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 on-board RAID (MegaRAID ROMB) has a feature to divide a single disk group into several
logical drives. The on-board RAID (MegaRAID ROMB) recognizes these virtual disks as if it were
a single HDD. The on-board RAID (MegaRAID ROMB) accesses to more than one HDD
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 HDD. This can provide high reliability for the system.
