2.3 Installation in Windows
1. When Windows has started up, a message
appears along the lines of "Windows must
install driver software for the RAID controller".
2. Select "Locate and install driver software
(recommended)".
3. Windows asks you to install the disk that
accompanied the RAID controller. Insert the
CD provided in your CD drive and click "Next".
4. Windows will install the drivers. Then click
"Close".
The card is now installed and ready for use.
Note: In order to install an operating system on
an empty hard disk connected to a Serial ATA
RAID card, it is necessary to create a diskette
with the drivers for the RAID card.
This is done by copying the files in the "D:\PCI_IO
\Sata\Raid" folder onto a diskette. Please use
this diskette during the installation of the
operating system.
3 Introduction to RAID
The card's RAID functions provide increased
speed and data security. RAID stands for
Redundant Array of Independent Disks, and can
be used when two hard disks are connected to
the card. RAID can be set up in several different
configurations. This card supports two
configurations: Mirroring (RAID 1) and Striping
(RAID 0).

Mirroring:
Mirroring enables you to mirror a disk. Mirroring
provides greater data security by coupling two
physical hard disks in such a way that they
appear as a single disk. All data is written to
both disks simultaneously, so both disks always
have identical data on them. If there is an error
on one of the disks, no data is lost and you can
use the other disk in the set. This protects data
in the event of crashes and ensures high
operating reliability and short downtimes in the
event of problems.
With mirroring, the smallest disk is the common
denominator for the capacity available. For
example, a 100 GB and 150 GB hard disk set will
appear as a single 100 GB disk.
NB: Mirroring only protects against hardware
failure. If a software error occurs e.g. in the
operating system, both disks will contain the
error.
Striping:
Note: When creating a striped disk set, all data
on the disks to be included in the disk set will
be deleted.
With striping you can connect two actual hard
disks together to form one unit. In the control
system the disks will appear as one physical disk
with double capacity. When data is written to
the disk, part of each file is stored on each of
the disks, thus increasing writing speed
considerably, at the same time increasing the
computer's overall performance. Striping
requires a minimum of two hard disks. When
you make a striped disk set, the smallest disk
sets the common denominator for size. If, for
example, you have one 100 GB hard disk and
one 150 GB one, the joined disk will have a
capacity of 200 GB in total, as each will count
as 100 GB disks. If two different sized disks are
connected to the controller, the smaller disk must
be connected to port 1 on the controller. It is
recommended to use identical hard disks in a
striped disk set.
