Asus DSEB-D16 Computer Hardware User Manual


 
ASUS DSEB-D16 Series 5-1
5.1 Setting up RAID
The motherboard comes with the following RAID solutions:
DSEB-D16 model
LSI Software RAID Conguration Utility and the Intel Matrix Storage Manager
embeded in the Intel 6321ESB Southbridge supports Serial ATA hard disk
drives and RAID0, RAID1, and RAID10 congurations. The Intel Matrix
Storage Manager also supports RAID5 conguration.
DSEB-D16/SAS model
Intel Matrix Storage Manager embeded in the Intel 6321ESB Southbridge
supports Serial ATA hard disk drives and RAID0, RAID1, RAID10 and RAID5
congurations.
LSI1068 PCI-X SAS controller supports SAS disk drives and RAID0, RAID1,
and RAID1E conguration.
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 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 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 CD to a oppy disk before you
install an operating system to the selected hard disk drive.
