5 SCSI Utilities
Ultra2 SCSI I/O Subsystem
Your new SYD6IBA2 high-performance Motherboard is equipped with the onboard Adaptec® AIC-7890 Ultra2 SCSI host adapter for your high bandwidth applications, providing data transfer rates of up to 80 Mbytes per second. The Ultra2 SCSI is an input/output bus interface that provides a powerful multitasking interface between your computer’s PCI bus and your SCSI devices.
With SCSI, you can connect a variety of devices on your computer (Hard/Floppy Disk Drives, CD-ROM Drives, Scanners, Tape Drives, Removable Media Drives, etc.) in a daisy-chain topology to a common host adapter. Daisy-chaining SCSI devices allows them to communicate with each other by sending commands and data via the SCSI bus.
The AIC-7890 Ultra2 SCSI provides maximum data transfer rates of 20 Mbytes/sec in the narrow 8-bit mode (Fast SCSI) and 40 Mbytes/sec in the wide 16-bit mode (Ultra SCSI), and 80 Mbytes/sec in the LVD mode (Ultra2 SCSI)
Installing SCSI Devices
Your Motherboard features two internal SCSI connectors onboard, and comes with one 50- pin flat cable, one 68-pin flat cable, and one 68-pin Ultra2 cable.
50-pin Fast SCSI Connector
50-pin Fast SCSI internal connector
Narrow SCSI allows data transfer rates of up to 20 Mbytes/sec. With Narrow SCSI, you can connect up to 7 internal Fast SCSI devices to the 50-pin Fast SCSI connector on the Motherboard. Use the enclosed Narrow SCSI cable to connect up to 2 internal SCSI devices.
If you are connecting more than 2 internal SCSI devices, you must use an internal SCSI cable with enough connectors to accommodate all your devices. Contact your dealer for special cable service.
When Fast SCSI devices are connected to the bus, the total length of all cables is not to exceed 3 meters (9.8 ft.) to ensure reliable operation.
