Adaptec 29160 Installation Guide - Page 3

INTRODUCTION 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 computer with 64- or 32-bit PCI expansion slots. The Adaptec SCSI Card 39160 has two independent SCSI channels, each with a maximum throughput of 160 MBytes/sec. SCSI Channel A (marked "CH 1/A" on the card) has two internal connectors and one external connector. SCSI Channel B (marked "CH 2/B" on the card) has one internal and one external connector. 68-pin internal LVD/SE 68-pin internal LVD/SE connector Channel B connector Channel A 68-pin external LVD/SE connector Channel A 68-pin external LVD/SE connector Channel B Narrow connector Channel A You can connect Ultra160 and Ultra2 SCSI devices to the 68-pin Low Voltage Differential/Single-Ended (LVD/SE) connectors on both SCSI channels. Or you can operate the newer Ultra160 and Ultra2 devices at their maximum speed on Channel B while at the same time using legacy SCSI devices on Channel A. 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.
