Abstract
A data storage system wherein a host computer is coupled to a bank of disk drives through a system interface. The interface includes 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 front-end portion of the directors is coupled to the host computer through front-end input/output adapters. Each one of the front-end directors includes a fiber channel hub. The hub is configured to provide a selected one of a plurality of fiber channel loops between one of the front-end directors and a selected one, or more, of a plurality of host computer sections. The fiber channel hub includes a plurality of transceivers each one being adapted to communicate with a corresponding one of the plurality of host computer sections. A plurality of multiplexer sections is coupled to a said one of the directors through a configurable fiber channel loop. Each one of such multiplexer sections is coupled to a corresponding one of the plurality of host computer sections through a corresponding one of the transceivers. Each one of the multiplexer sections is re…
