3.3 RAIDcongurations
The motherboard supports the following RAID congurations.
RAID 0 (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. Use of two
new identical hard disk drives is required for this setup.
RAID 1
(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. Use two new drives or use an existing drive and a new drive
for this setup. The new drive must be of the same size or larger than the
existing drive.
JBOD (Spanning) stands for Just a Bunch of Disks and refers to hard disk
drives that are not yet congured as a RAID set. This 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 other
RAID performance benets.
