The Adaptec SCSI Card 39320D enables you to connect up to 30
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 39320D has two independent SCSI
channels, each with a maximum throughput of 320 MB/sec. SCSI
Channel A (marked CH A on the card) has one internal
68-pin Low Voltage Differential/Single-Ended (LVD/SE)
connector and one external very high-density cable interconnect
(VHDCI) connector. SCSI Channel B (marked CH B on the card)
has one external VHDCI connector.
You can connect Ultra320/160 and Ultra2 SCSI devices to the
68-pin LVD connectors on both SCSI channels. When connecting
these newer devices along with older legacy SCSI devices,
Adaptec recommends that you dedicate them as separate
channels. See Support for Older SCSI Devices on page 2 for more
information.
Although the Adaptec SCSI Card 39320D is a 64-bit PCI 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 39320D
•Set up SCSI devices
•Connect SCSI devices
