RAID Support

RAID configurations

The motherboard supports Intel
and RAID 10 solution.
If you want to install a Windows
set, you have to create a RAID driver disk and load the RAID driver during OS installation.
Refer to section Creating a RAID driver disk for details.

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 5 strips both data and parity information across three or more hard disk drives. Among
the advantages of RAID 5 configuration include better HDD performance, fault tolerance,
and higher storage capacity. The RAID 5 configuration is best suited for transaction
processing, relational database applications, enterprise resource planning, and other
business systems. Use a minimum of three identical hard disk drives for this setup.
RAID 10 is data striping and data mirroring combined without parity (redundancy data)
having to be calculated and written. With the RAID 10 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.
