5.1 Setting up RAID
The motherboard comes with the following RAID solutions:
• The N V I D I A
N V I D I A N V I D I A N V I D I A N V I D I A ® ® ® ® ® nForce Professional 2200 nForce Professional 2200 nForce Professional 2200 nForce Professional 2200 nForce Professional 2200 chipset comes with a
built-in SATA RAID controller that allows you to configure RAID 0, RAID 1,
RAID 1+0 and JBOD with IDE and SATA hard disk drives.
• The LSI 1020A SCSI RAID controller LSI 1020A SCSI RAID controller LSI 1020A SCSI RAID controller LSI 1020A SCSI RAID controller LSI 1020A SCSI RAID controller supports SCSI hard disk
drives that you can configure as RAID 0, RAID 1, or RAID 1-E.

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.
RAID 1 RAID 1 RAID 1 RAID 1 RAID 1- E - E - E - E - 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.
R A I D 1 + 0 R A I D 1 + 0 R A I D 1 + 0 R A I D 1 + 0 R A I D 1 + 0 is data mirroring and data striping combined. This configuration
uses two or more drives that are mirrored together and then the mirrors
are striped together.
J B O D J B O D J B O D J B O D J B O D (Spanning) stands for J u s t a B u n c h o f D i s k s J u s t a B u n c h o f D i s k s J u s t a B u n c h o f D i s k s J u s t a B u n c h o f D i s k s J u s t a B u n c h o f D i s k s 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.
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 Chapter 6 for details.
