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).
