Abstract
In one aspect, the invention is a tuned stub, SCSI topology comprising a SCSI bus, a breakout node on the SCSI bus, an external SCSI connector on the SCSI bus at a first point defined by a first propagation delay; an internal SCSI connector on the SCSI bus at a second point defined by a second propagation delay, the first and second propagation delays being substantially equal; a SCSI adapter electrically tapping the breakout node; and a terminator electrically tapping the breakout node.
