Overview Ultra160 SCSI on the Adaptec SCSI Card 39160 The Adaptec SCSI Card 39160 enables you to connect up to 30 SCSI devices—such as very large arrays of high-performance HDDs, external storage subsystems, clustered configurations, Ultra160 hard disk drives, scanners, and CD-ROM drives—to any Intel-based com- puter with 64- or 32-bit PCI expansion slots. Ultra160 is a new gener- ation of SCSI technology that increases SCSI performance from 80 MBytes/sec to 160 MBytes/sec. In addition to pr

Although the Adaptec SCSI Card 39160 is a 64-bit PCI card, it also works in a 32-bit PCI slot. When installed in a 32-bit PCI slot, the card automatically runs in the slower 32-bit mode. This User’s Reference provides information about troubleshooting, SCSI termination, and other important topics. It also explains how to use the built-in SCSISelect utility if you

Overview SCSI IDs Each device attached to the Adaptec SCSI Card 39160, as well as the Adaptec SCSI Card 39160 itself, must be assigned a unique SCSI ID number from 0 to 15 for each of the two SCSI buses. A SCSI ID uniquely identifies each SCSI device on the SCSI bus and determines priority when two or more devices are trying to use the SCSI bus at the same time. Refer to the device’s documentation to set the SCSI ID. Here are some general guidelines for SCSI IDs: ■ For internal SCSI device

Adaptec SCSI Card 39160 User’s Reference Terminating the SCSI Bus To ensure reliable communication on the SCSI bus, the ends of the SCSI bus must be properly terminated. This is accomplished when the device at the end of each cable, or the end of the cable itself, has a terminator installed (or enabled). Terminators must be removed, or termination must be disabled, on devices between the ends of each cable. Since the method for terminating a SCSI device can vary widely, refer to the device

Adaptec SCSI Card 39160 User’s Reference SCSI hard disk drives running under other operating systems, see the operating system documentation. Using Ultra160 Hard Disk Drives ■ We recommend that you connect your LVD (Ultra160 and Ultra2) SCSI devices to SCSI Channel B and your non-LVD SCSI devices (if any) to SCSI Channel A. This allows the LVD SCSI devices to run at their maximum performance levels of 160 MBytes/sec or 80 MBytes/sec. Or you can connect LVD SCSI devices to both SCSI channel

1 1 Adaptec SCSI Card 39160 User’s Reference Installing Multiple SCSI Cards ■ You can install multiple SCSI cards in your computer; you are limited only by the available system resources (for example, IRQ settings, I/O port addresses, BIOS addresses, and so forth). ■ Each SCSI card you install forms a separate SCSI bus with a different set of SCSI devices. SCSI IDs can be reused as long as the ID is assigned to a device on a different SCSI card (for example, each SCSI card can have a devic
