Chapter 5: Software support

If you use either Windows

XP or Windows

2000 operating system

(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.

5.4 RAID configurations

The motherboard comes with the ITE

8212F and the Intel

ICH6R

Southbridge RAID controllers that allow you to configure IDE and 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.

JBODJBOD

JBOD

(Spanning)

stands for

Just a Bunch of DisksJust a Bunch of Disks

Just a Bunch of Disks and refers to hard

disk drives that are not yet configured as a RAID set. This configuration

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 benefits.

Matrix Storage. Matrix Storage.

Matrix Storage. The Intel

Matrix Storage technology supported

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

Matrix Storage technology

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.
