Apple Dual Channel Ultra320 SCSI PCI-X Card interface cards/adapter

Dual Channel Ultra320 SCSI PCI-X Card Capable of 64-bit/133 MHz PCI-X bus operation (also supports 33, 66, and 100 MHz speeds at 3.3V or 5V signaling), this advanced SCSI card provides two independent 320 MBps channels for connection to high-performance disk and RAID systems as well as support for tape backup devices.

This dual-channel card has two 68-pin VHDCI connectors on it for connection to high-speed, 16-bit low-voltage differential (LVD) or single-ended (SE) external devices. You can connect standard SCSI (SCSI-1), Fast SCSI (SCSI-2), and Ultra SCSI (also called Ultra Narrow SCSI) peripherals to the Ultra320 SCSI card with proper cabling (not included).

Note: Different types of SCSI devices connected to each independent SCSI channel operate only as fast as the slowest device on the chain. For example, a SCSI-2 (10MBps) tape drive and an Ultra160 SCSI (160MBps) hard disk on the same SCSI channel will both operate at 10MBps.
