SCSI Gables: More Than a Couple of Connectors and a Few Pieces of Wire

摘要

For more than fifteen years, Paralan Corporation has been assisting customers with SCSI bus subsystem performance problems. Many times, frustrated system integrators end up forfeiting all their profits making weekly trips to the customer's site to trouble-shoot system performance problems. Through this experience, it has become clear to those of us doing the troubleshooting that poorly designed and manufactured cabling is usually the culprit preventing a SCSI subsystem from running reliably with maximum data throughput. Fortunately, the problem is easy to correct. To prevent problems, designers must carefully define and build the cables to the specification and test them rigorously for reliability. With SCSI running at data rates of up to 320 Megabytes/sec, reliable SCSI cables are essential. The specification is clear on how to design and build reliable cables that will accommodate high speeds.
