6-2 Chapter 6: RAID conguration
6.1 Setting up RAID
The motherboard comes with the Intel® C204 controller that supports the following SATA
RAID solutions:
LSIMegaRAIDsoftwareRAIDCongurationUtility
(default) with RAID 0, RAID 1,
and RAID 10 support (for both Linux and Windows OS).
Intel Rapid Storage Technology
with RAID 0, RAID 1, RAID 10, and RAID 5 support
(for Windows OS only).
6.1.1 RAIDdenitions
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
conguration 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 1E
(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 conguration.
RAID 10 is data striping and data mirroring combined without parity (redundancy data) having
to be calculated and written. With the RAID 10 conguration you get all the benets of both
RAID 0 and RAID 1 congurations. Use four new hard disk drives or use an existing drive
and three new drives for this setup.
RAID 5 stripes both data and parity information across three or more hard disk drives. Among
the advantages of RAID 5 conguration include better HDD performance, fault tolerance, and
higher storage capacity. The RAID 5 conguration 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.
If you want to boot the system from a hard disk drive included in a created RAID set,
copy rst the RAID driver from the support DVD to a oppy disk before you install an
operating system to the selected hard disk drive.
Please refer to chapter 2 for how to select the RAID conguration utility. Move the
jumper to choose between LSI MegaRAID and Intel® Rapid RAID.
