Abstract
A data storage system wherein a host computer is coupled to a bank of disk drives through a system interface. The interface has a plurality of directors and a memory interconnected by a plurality of busses for controlling data transfer between the host computer and the bank of disk drives as such data passes through the memory. A portion of the directors have input/output interfaces coupled to disk drive bank through input/output adapters. The system interface includes a system printed circuit board, such printed circuit board having the directors and the memory plugged into one side thereof and having the input/output adapters plugged into an opposite side thereof. A disk backplane is provided. The disk backplane has having plugged therein: a pair of disk drive sections, each section having a plurality of disk drives in the bank of disk drives; and a pair of port by-pass card, each one of the port by-pass cards being coupled to a corresponding one of the pair of disk drive sections. Each one of the input/output adapters includes a fibre channel hub. The hub is configured to provide a selected one of a plurality of fibre channel loops between one of the directors and a selected one…
