DATA STORAGE SYSTEM

摘要

A data storage system having a plurality of disk drives. Each one has a pair of ports. A pair of directors controls the flow of data to and from the disk drives. A first and second fibre channel port by-pass selector section are provided. The first fibre channel selector section includes: an input/output port coupled to a first one of the directors; and, a plurality of output/input ports connected between a first one of the ports of the plurality of desk drives through a first plurality of fibre channel links. The first fibre channel port by-pass selector section is adapted to couple the first one of the directors serially to one, or ones, of the first ports of the plurality of disk drives through a first fibre channel selectively in accordance with a control signal fed to the first fibre channel by-pass selector section. The first fibre channel includes one, or more, of the first plurality of fibre channel links. The second fibre channel port by-pass selector section is similarly configured.
