2 How to Install Accessories Inside Your PC Workstation
Installing Mass Storage Devices
Installing a Hard
Disk Drive
The computer has two integrated SCSI controllers and an integrated
Enhanced IDE controller.
•
The Enhanced IDE controller with one channel supports up to two
IDE devices. An integrated Ultra ATA-33 controller on the PCI bus
supports the fastest IDE devices (33 MB per second).
•
The Ultra wide 16-bit SCSI controller is dedicated to hard disk drives
and supports up to five internal SCSI devices.
•
The Ultra narrow 8-bit SCSI controller supports up to two internal or
seven external SCSI devices. When an external device is connected
to the system, the narrow SCSI controller automatically switches to
non-Ultra, or standard mode (maximum capacity of 10 MB per
second).
Disk Striping
To achieve top performance through disk striping, a RAID
port
™
is
provided on the system board aligned with PCI socket 3.
When the Adaptec
®
RAID port adapter is installed in the PCI socket
and RAID port , the adapter sets up and accelerates disk striping on
hard disks connected to the Ultra wide 16-bit SCSI controller. The
Adaptec
®
RAID port adapter should be used with two hard disks.
NOTE Disk striping is supported only in Windows NT 4.0.
The Adaptec CI/O Array Manager software can be used to manage and
view the performance of the adapter.
Although the RAID port adapter is normally set up to maximize disk
performance (“RAID 0” configuration), it can instead be configured to
provide mirroring for extra data security (“RAID 1” configuration).
For more information, refer to “The HP FastRAID Option” on page 87.
Before Installing an
IDE Hard Disk
Refer to the drive’s installation guide to see if you must set jumpers or if
there is a special installation procedure to follow.
