5.1 Setting up RAID The motherboard comes with the following RAID solutions: KFSN4-DRE; KFSN4-DRE/2S model • The NVIDIA® nForce Professional 2200 chipset comes with a built-in SATA RAID controller that allows you to configure RAID 0 and RAID 1 with SATA hard disk drives. KFSN4-DRE/SAS model • The NVIDIA® nForce Professional 2200 chipset comes with a built-in SATA RAID controller that allows you to configure RAID 0 and RAID 1 with SATA hard disk drives. • LSI1064E PCI-E SAS controller supports SAS disk drives and RAID0, RAID1, and RAID1E configuration. 5.1.1 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. RAID 1-E (Enhanced RAID 1) has a striped layout with each stripe unit having a secondary (or alternate) copy stored on a different disk. You can use three or more hard disk drives for this configuration. 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.

Setting up RAID
The motherboard comes with the following RAID solutions:
KFSN4-DRE; KFSN4-DRE/2S model
The NVIDIA
®
nForce Professional 2200 chipset comes with a built-in SATA
RAID controller that allows you to configure RAID 0 and RAID 1 with SATA
hard disk drives.
KFSN4-DRE/SAS model
The NVIDIA
®
nForce Professional 2200 chipset comes with a built-in SATA
RAID controller that allows you to configure RAID 0 and RAID 1 with SATA
hard disk drives.
LSI1064E PCI-E SAS controller supports SAS disk drives and RAID0, RAID1,
and RAID1E configuration.
5.1.1
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.
RAID 1-E
(Enhanced RAID 1)
has a striped layout with each stripe unit having a
secondary (or alternate) copy stored on a different disk. You can use three or more
hard disk drives for this configuration.
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.
