Installing a Hard
Disk Drive
Disk Striping
NOTE
Before Installing an
IDE Hard Disk
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).
To achieve top performance through disk striping, a RAIDport
provided on the system board aligned with PCI socket 3.
®
When the Adaptec
and RAIDport, the adapter sets up and accelerates disk striping on
hard disks connected to the Ultra wide 16-bit SCSI controller. The
®
Adaptec RAIDport adapter should be used with two hard disks.
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 RAIDport 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.
Refer to the drive's installation guide to see if you must set jumpers or if
there is a special installation procedure to follow.
