ASUS DSEB-DG Series 5-1
5.1 Setting up RAID
The motherboard comes with the following RAID solutions:
DSEB-DG model
• LSI Logic Embeded SATA RAID 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.

The Marvell
®
88SE6145 is a host bus adapter chip between PCI-Express
and Serial ATA (SATA)/Parallel ATA (PATA) devices. It employs the latest
Serial ATA (SATA) Phy technology, operating at 1.5 Gb/s or 3.0 Gb/s. The
motherboard supports the following RAID congurations: RAID0, RAID1,
RAID10 and RAID5.
DSEB-DG/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.
