Ultra320 SCSI on the Adaptec SCSI Card
The Adaptec SCSI Card enables you to connect up to 30 SCSI
devices—such as very large arrays of high-performance hard disk
drives, external storage subsystems, Ultra320/Ultra160 hard disk
drives, scanners, and CD-ROM drives—to any Intel-based or Intel-
compatible computer with 64- or 32-bit PCI/PCI-X expansion slots.
Ultra320 is an enhanced SCSI technology that transfers data at up
to 320 MB/sec. Ultra320 SCSI allows cable length of up to 12
meters for optimal connectivity and flexibility.
The Adaptec SCSI Card 39320A has two independent SCSI
channels, each with a maximum throughput of 320 MB/sec per
channel.
