by: Charles Gimar Performance Analyst Storage Components Division LSI Logic Corp. Colorado Springs, CO Also appeared in EE Times, Nov. 3, 2000. The growing demand for bandwidth to and from storage is putting pressure on protocols like the Small Computer Systems Interface (SCSI) point-to-point data-transmission standards. Such protocols must continually evolve to provide more data-transmission… Read more »

Simple Expanders Extend SCSI Bus Reach into the Future (PDF) A white paper by David Rotman of Compaq Computer Corp. and Harry Mason of LSI Logic discussing how simple expanders (versus bridging expanders) allow for a significant increase in overall attainable SCSI bus length and SCSI domain diameter. SCSI expanders are active interconnect components that… Read more »

SCSI Remains the I/O Interface of Choice for Workstations: An analysis comparing SCSI and Ultra DMA (PDF) A White Paper prepared by Tom Martin and Andy Scholl of Adaptec, for the SCSI Trade Association Summary The new Ultra DMA claims to double drive performance, yet benchmark tests demonstrate a performance gain of less than five… Read more »
