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 memory with a high address memory section and a low address memory section. A plurality of directors control data transfer between the host computer and the bank of disk drives as such data passes through the memory. A pair of high address busses electrically is connected to the high address memory and a pair of low address busses is electrically connected to the low address memory. Each one of the directors is electrically connected to one of the pair of high address busses and one of the pair of low address busses. A front-end portion of the directors is electrically connected to the host computer and a rear-end portion of the directors is electrically connected to the bank of disk drives. The bank of disk drives has a plurality of sets of electrically connected disk drives, each one of the sets being connected to a corresponding one of the input/output interfaces of a corresponding one of the rear-end directors through the adapter card connected to such corresponding one of the rear-end directors and, through the printed circuit board, to the adapter …
