5.1 RAID configurations
The server system/motherboard comes with the I n t e l I n t e l I n t e l I n t e l I n t e l ® ® ® ® ® I C H 6 R I C H 6 R I C H 6 R I C H 6 R I C H 6 R
Southbridge chip that supports up to four Serial ATA hard disk drives with
RAID 0, RAID 1, or Intel
® Matrix Storage configuration.
Refer to the RAID definitions below.

R A I D 0 R A I D 0 R A I D 0 R A I D 0 R A I D 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 RAID 1 RAID 1 RAID 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.

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.

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 0
and RAID 1 sets. This technology also allows you to change the hard disk
drive partition size without losing any data.
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 CD to a
floppy disk before you install an operating system to the selected hard
disk drive. Refer to section “2. RAID driver installation” for details.
