Installing a Hard
Disk Drive
Disk Striping
NOTE
Before Installing an
IDE Hard Disk
This PC Workstation has an integrated Ultra SCSI controller, an Ultra
SCSI interface board and an integrated Ultra ATA-33 IDE controller.
The Ultra ATA-33 IDE controller, on the PCI bus, supports up to two
•
fast (33 MB per second) IDE devices.
The Ultra wide 16-bit SCSI controller is dedicated to hard disk drives
•
and supports up to five internal SCSI devices.
The Ultra SCSI 16-bit interface board, installed in a PCI slot,
•
supports up to 13 external 16-bit SCSI devices and automatically
switches to non-Ultra or standard mode (data transfer rate of 20 MB
per second). The Ultra 8-bit internal connector supports up to two
internal peripherals at up to 20 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 RAIDport adapter is installed in the PCI socket
and RAIDport, the adapter sets up and accelerates disk striping on
hard disks connected to the internal UltraWide 16-bit SCSI controller.
®
The Adaptec RAIDport adapter should be used with one or two
stripped 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 94.
Refer to the drive's installation guide to see if you must set jumpers or if
there is a special installation procedure to follow.
