Abstract
A data storage system wherein a host computer is coupled to a bank of disk drives through an interface. The interface has a plurality of directors and a memory interconnected by a bus. The directors control data transfer between the host computer and the bank of disk drives as such data passes through the memory. The interface includes a plurality of ESCON adapters, a front end portion of the directors being coupled between the host computer and the busses through the ESCON adapters. Each one of such adapters includes a plurality of adapter ports each one being coupled to a corresponding port of the host computer. Each one of the adapters also includes a plurality of adapter board gate arrays and a plurality of optic interfaces. Each one of the optic interfaces is coupled between a corresponding one of the adapter port and a corresponding one of the adapter board gate arrays.
