Abstract
A system for coupling data between a host computer and a bank of disk drives. The system includes a plurality of directors for controlling the flow of the data between host computer and the bank of disk drives. Each one of the directors has a primary port and a secondary port. The system includes a first I/O section coupled to a first one of a pair of disk drive sections in the bank of disk drives and a second I/O section coupled to a second one of the pair of disk drive sections in the bank of disk drives. A backplane is provided for electrically interconnecting: the primary port of a first one of a pair of the directors to the first I/O section through a first differential data bus; the secondary port of the first one of the pair of directors to the second I/O section through a first single ended data bus; the primary port of a second one of the pair of directors to the second I/O section through a second differential data bus; and, the secondary port of the second one of the pair of directors to the first I/O section through a second single ended data bus. Each one of the first and second I/O sections includes a single ended/differential data bus converter. The converter of the …
