5-30 Chapter 5: Software support
If you want to boot the system from a hard disk drive included in a created RAID
set, copy rst the RAID driver from the support DVD to a oppy disk before you
install an operating system to the selected hard disk drive. Refer to section
5.5
Creating a RAID driver disk
for details.
5.4 RAID congurations
The motherboard comes with the Intel
®
ICH9R Southbridge RAID controller that
allow you to congure IDE and Serial ATA hard disk drives as RAID sets. The
motherboard supports the following RAID congurations.
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 conguration 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.
