ASUS Z9PE-D8 WS 5-3
5.1 Setting up RAID
The motherboard supports the following SATA RAID solutions:
LSI MegaRAID software RAID Conguration Utility
with RAID 0, RAID 1,
and RAID 10 support (for both Linux and Windows OS).
Intel Rapid Storage Technology enterprise SCU / SATA Option ROM
Utility
with RAID 0, RAID 1, RAID 10, and RAID 5 support (for Windows OS
only).
Marvell RAID Utility
with RAID 0, RAID 1, and RAID 10 support.
5.1.1 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.
