Installing hard disks

The motherboard supports Ultra DMA 100/66 and Serial ATA hard disk

drives. For optimal performance, install identical drives of the same model

and capacity when creating a disk array.

Installing Serial ATA (SATA) hard disks

To install the SATA hard disks for a RAID configuration:

1. Install the SATA hard disks into the drive bays.

2. Connect the SATA signal cables.

3. Connect a SATA power cable to the power connector on each drive.

If you want to boot the system from a hard disk drive included in a RAID

set, copy first the RAID driver from the support CD to a floppy disk

before you install an operating system to a selected hard disk drive.

Refer to section “5.6 Creating a RAID driver disk” for details.

Refer to the RAID controllers user manual in the motherboard support

CD for detailed information on RAID configurations. See section “5.2.4

Manuals menu.”

5.4 RAID configurations

The Intel

ICH7-M (DH) Southbridge features an onboard RAID controller

that allow you to configure Serial ATA hard disk drives as RAID sets. The

motherboard supports the following RAID configurations.

RAID 0RAID 0

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 1RAID 1

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.

RAID 0+1RAID 0+1

RAID 0+1 is

data striping

and

data mirroring

combined without parity

(redundancy data) having to be calculated and written. With the RAID 0+1

configuration you get all the benefits of both RAID 0 and RAID 1

configurations. Use four new hard disk drives or use an existing drive and

three new drives for this setup.
