The ANSI standards T10 committee is revising the SCSI Parallel Interface (SPI-3). This document is the basis of the Ultra160 SCSI technology. Evolutionary changes have been made to the existing SCSI protocol (SPI-2) to increase performance, manageability, and reliability. All changes are incremental, and existing SCSI protocols are maintained for backward compatibility. Three new underlying components of Ultra160 SCSI are Double Transition Clocking, Cyclical Redundancy Checks (CRC), and Domain Validation. – What technology Enables Ultra160 SCSI? Ultra160 SCSI doubles transfer rates to 160 Megabytes per second by using both edges of the request/acknowledge signal to clock data. This creative solution provides designers with the choice of improving speed, reliability or connectivity. It allows system designers to choose bus bandwidths up to 160 MB/second using existing Ultra2 SCSI cable plants. Alternatively, this technology lets designers maintain Ultra2 SCSI speeds (80 MB/second) and i
