6.1 Setting up RAID The motherboard comes with the Intel® C202 controller that supports the following SATA RAID solutions: • Intel Rapid Storage Technology with RAID 0 and RAID 1 support (for Windows OS only). 6.1.1 RAID definitions 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 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. • If you want to boot the system from a hard disk drive included in a created RAID set, copy first the RAID driver from the support DVD to a floppy disk before you install an operating system to the selected hard disk drive. • Please refer to chapter 2 for how to select the RAID configuration utility. Move the jumper to choose between LSI MegaRAID and Intel® Rapid RAID. 6-2 Chapter 6: RAID configuration

Setting up RAID
The motherboard comes with the Intel
®
C202 controller that supports the following
SATA RAID solutions:
•
Intel Rapid Storage Technology
with RAID 0 and RAID 1 support (for
Windows OS only).
6.1.1
RAID definitions
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 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.
•
If you want to boot the system from a hard disk drive included in a created
RAID set, copy first the RAID driver from the support DVD to a floppy disk
before you install an operating system to the selected hard disk drive.

Please refer to chapter 2 for how to select the RAID configuration utility.
Move the jumper to choose between LSI MegaRAID and Intel

Rapid RAID.
