AIC-7892

R AIC -7892 ™ Single-Channel PCI-to-Ultra160 SCSI Single-Chip Host Adapter Overview The Adaptec® AIC-7892 single-chip host adapter provides outstanding performance and flexibility to meet tomorrow’s requirements today. Ultra160 SCSI delivers data transfer rates up to 160 MByte/sec to address emerging bandwidth-hungry applications, such as real-time video, data mining, Internet/ Intranet, and scientific modeling and simulation. The AIC-7892 chip features a 66 MHz, 64-bit, PCI interface for next-generation server, workstation, and high-end desktop systems. SCSI Bus Configuration Testing The AIC-7892 fully supports Ultra160 and Ultra3 SCSI Domain Validation. Domain Validation provides SCSI bus configuration testing to help ensure Ultra160 SCSI devices operate at optimum speed. Long Cables The AIC-7892 supports a maximum of 15 LVD devices on 12 meters of cable. In a point-to-point configuration, the maximum cable length extends to 25 meters. The AIC-7892 is fully compatible with existing Ultra2 SCSI supported cable configurations. The cable-length distances provide greater system configuration flexibility – especially for clustering and RAID applications. The AIC-7892 also supports High Voltage Differential (HVD) busses when used with external HVD transceivers. Backward Compatibility The AIC-7892 incorporates an advanced multimode I/O cell that supports Ultra2, Ultra3, and Ultra160 SCSI LVD devices, as well as single-ended (SE) devices. With only Ultra2 and Ultra160 devices att...
