Abstract
A system interface having a plurality of directors, one portion of such directors being adapted for coupling to a host computer/server and another portion of the directors being adapted for coupling to a bank of disk drives. The plurality of directors are interconnected through a network. A common resource section is provided having a resource shared among the plurality of directors. The common shared resource section includes a shared computer code used by the plurality of directors. The code includes computer code for booting up each one of the plurality directors. The common shared code storage section is interconnected to the directors through the network. A second, redundant common shared resource section is provided. The network is a packet switching network.
