The Adaptec SCSI Card 29320 enables you to connect up to 15
Low Voltage Differential (LVD) and/or 15 Single-Ended (SE)
SCSI devices—such as very large arrays of high-performance
hard disk drives, external storage subsystems, Ultra320/160 hard
disk drives, scanners, and CD-ROM drives—to any Intel-based
computer with 64- or 32-bit PCI/PCI-X expansion slots.
The Adaptec SCSI Card 29320 has one internal and one external
68-pin LVD/SE connector and two internal SE SCSI connectors
(one 68-pin and one 50-pin).
Although the Adaptec SCSI Card 29320 is a 64-bit PCI/PCI-X
card, it also works in a 32-bit PCI slot. When installed in a 32-bit
PCI slot, the card automatically runs in the slower 32-bit mode.
This installation guide explains how to:
•Install the Adaptec SCSI Card 29320
•Set up SCSI devices
•Connect SCSI devices
INTRODUCTION
If you connect Wide Ultra/Ultra SCSI devices to the
same SCSI connectors as Ultra320/160 and Ultra2 SCSI
devices, the data transfer rate for the Ultra320/160 and Ultra2
SCSI devices will drop to Ultra SCSI performance levels.
Attach only Ultra320/160 and Ultra2 SCSI devices to the
LVD/SE connectors to achieve maximum data transfer rates.
