RAID configurations

The motherboard comes with the Intel
that allow you to configure IDE and Serial ATA hard disk drives as RAID
sets. The motherboard supports the following RAID configurations.
R A I D 0 (Data striping) optimizes two identical hard disk drives to read and R A I D 0 R A I D 0
R A I D 0 R A I D 0
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.
R A I D 1 (Data mirroring) copies and maintains an identical image of data R A I D 1 R A I D 1
R A I D 1 R A I D 1
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
configuration 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.

by the ICH6R chip allows you to create a RAID 0 and a RAID 1 set using
only two identical hard disk drives. The Intel
creates two partitions on each hard disk drive to create a virtual RAID O
and RAID 1 sets. This technology also allows you to change the hard disk
drive partition size without losing any data.
If you use either Windows
(OS), copy first the RAID driver from the support CD to a floppy disk
before creating RAID configurations. Refer to section "5.5 Creating a
RAID driver disk" for details.
