5.4 RAID congurations
The motherboard comes with the VIA VT8237A controller integrated in the
SouthBridge to support Redundant Array of Independent Disks (RAID)
congurations. Using two Serial ATA hard disks, you can set up RAID 0,
RAID 1, and JBOD congurations. The following denes the different RAID
set congurations:
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
conguration 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 congured according to RAID. The JBOD
conguration 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 benets 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 congurations. Refer to section “5.5 м Creating a
RAID driver disk” for details.
