5.4 RAID congurations
The motherboard comes with the VIA VT8237A controller integrated in the
SouthBridge to support Redundant Array of Independent Disks (RAID)
congurations. Using two Serial ATA hard disks, you can set up RAID 0,
RAID 1, and JBOD congurations. The following denes the different RAID
set congurations:
RAID 0 (called data striping) optimizes two identical hard disk drives to
read and write data in parallel, interleaved stacks. Two hard disks perform
the same work as a single drive but at a sustained data transfer rate,
double that of a single disk alone, thus improving data access and storage.
RAID 1 (called data mirroring) copies and maintains an identical image
of data from one drive to a second drive. If one drive fails, the disk array
management software directs all applications to the surviving drive as
it contains a complete copy of the data in the other drive. This RAID
conguration provides data protection and increases fault tolerance to the
entire system.
JBOD stands for Just a Bunch of Disks or also called spanning, refers
to hard disks that are not yet congured according to RAID. The JBOD
conguration stores the same data redundantly on multiple disks that
appear as a single disk on the operating system. Spanning does not
deliver any advantage over using separate disks independently and does
not provide fault tolerance or performance benets of RAID.
If you use either Windows
®
XP or Windows
®
2000 operating system
(OS), copy rst the RAID driver from the support CD to a oppy disk
before creating RAID congurations. Refer to section “5.5 м Creating a
RAID driver disk” for details.
