Installing and Removing an Expansion Card
Your computer's motherboard features several expansion slots that can accommodate
accessory expansion cards, such as a SCSI board or a RAID board.
Specific Recommendations
RAID Controller
Take the following into consideration when installing either a S-ATA Disk array
controller or a SCSI Disk array controller.
Refer to the manual that comes with the RAID controller for more details.
■ Prepare the hard disk drives and cables corresponding to the RAID controller to be
installed.
■ Configure the Logical Settings of the hard disk drive.
■ Prepare the number of hard disk drives required for the desired RAID (Redundant
Array of Inexpensive [Independent] Disks) level.
page 92.
■ Installing hard disks in the disk array configuration or changing the RAID level
initializes hard disks. Make sure to backup any valuable data that may be present
on the hard disk drive before installing the disk mirroring controller board and
configuring the array.
■ Use hard disks of the same capacity and revolution for each pack to configure them
in the array.
■ The disk array configuration improves the disk reliability. On the other hand, the
disk capacity is reduced (not equal to the sum of the array's hard disks total
capacity).
■ Use an appropriate RAID configuration utility to configure the RAID.
■ When the disk array controller board is replaced, restore the disk array
configuration information to the new disk array controller board. Use the
configuration utility for the restoration. Refer to the RAID configuration utility
specific to your card for more details.
SCSI Controller
Take the following into consideration either when installing an SCSI controller or when
using SCSI hard disk drives as internal hard disk drives.
Refer to the manual that comes with the SCSI controller for details.
■ Prepare the hard disk drives (up to 4 drives) and cables appropriate to SCSI
controller to be installed.
■ Configure the Logical Settings of hard disk drive.
■ When the controller is chosen to boot on OS, install the hard disk controller in the
highest priority PCI slot, i.e. in the smallest PCI slot number.
