The Adaptec U320 SCSI RAID 0 or 1 enables you to connect up to 30 SCSI devices-such as Ultra320/Ultra160 hard disk drives, scanners, and CD-ROM drives-to any Intel-based or Intel-compatible system with 64- or 32-bit PCI/PCI-X expansion slots. Ultra320 is an enhanced SCSI technology that transfers data at up to 640 MB/sec. Ultra320 SCSI allows cable length of up to 12 meters for optimal connectivity and flexibility. The Adaptec U320 SCSI RAID 0 or 1 has two independent SCSI channels, each with a maximum throughput of 320 MB/sec. For optimum performance and throughput, the Adaptec U320 SCSI RAID 0 or 1 card must be installed in a 64-bit, 133-MHz, PCI-X slot with Ultra320 devices. However, the HBA is fully functional in legacy PCI systems because it supports conventional 33- and 66-MHz PCI transactions in both 32- and 64-bit modes. The HBA also supports legacy SCSI operations, such as SPI-3 Double Transition (DT) clocking. The Adaptec U320 SCSI RAID 0 or 1 card is backwards compatible with virtually any legacy Ultra2, Ultra, and Single-Ended (SE) SCSI device, except High Voltage Differential (HVD) devices. However, performance is degraded to SE speed, and SE cable length restrictions must be adhered to, when an SE device is connected to the bus. Dualindependent channels allow LVD and SE devices to operate separately at peak performance. Configuration Features Specification Feature

The Adaptec U320 SCSI RAID 0 or 1 enables you to connect up to 30 SCSI devices—such as Ultra320/Ultra160 hard
disk drives, scanners, and CD-ROM drives—to any Intel-based or Intel-compatible system with 64- or 32-bit
PCI/PCI-X expansion slots. Ultra320 is an enhanced SCSI technology that transfers data at up to 640 MB/sec.
Ultra320 SCSI allows cable length of up to 12 meters for optimal connectivity and flexibility.
The Adaptec U320 SCSI RAID 0 or 1 has two independent SCSI channels, each with a maximum throughput of 320
MB/sec.
For optimum performance and throughput, the Adaptec U320 SCSI RAID 0 or 1 card must be installed in a 64-bit,
133-MHz, PCI-X slot with Ultra320 devices. However, the HBA is fully functional in legacy PCI systems because it
supports conventional 33- and 66-MHz PCI transactions in both 32- and 64-bit modes. The HBA also supports legacy
SCSI operations, such as SPI-3 Double Transition (DT) clocking.
The Adaptec U320 SCSI RAID 0 or 1 card is backwards compatible with virtually any legacy Ultra2, Ultra, and
Single-Ended (SE) SCSI device, except High Voltage Differential (HVD) devices. However, performance is degraded
to SE speed, and SE cable length restrictions must be adhered to, when an SE device is connected to the bus. Dual-
independent channels allow LVD and SE devices to operate separately at peak performance.
