ABSTRACT:
A data storage system for transferring data between a host computer/server and a bank of disk drives through a system interface. The system interface includes a backplane; a first printed circuit board plugged into a first side of the backplane; a second printed circuit board plugged into the first side of the backplane. The first and second printed circuit boards are disposed in an overlaying relationship. A third printed circuit board is plugged into a second side of the backplane. The second side is opposite to the first side. A memory having at least a first portion thereof is disposed on the third printed circuit board. A plurality of directors controls data transfer between the host computer and the bank of disk drives as such data passes through the memory. A first plurality of the directors is coupled to the host computer/server. A first portion of such first plurality of directors is disposed on the first printed circuit boards and a second portion of the first plurality of directors is disposed on the second printed circuit board. A second plurality of the directors is coupled to the bank of disk drives. A first portion of such second plurality of directors is disposed on the first printed circuit boards and a second portion of the second plurality of the directors is disposed on the second printed circuit board. A first network is disposed on the first printed circuit board. The switch network has ports coupled to: the first portion of the first plurality of directors; the first portion of the second plurality of directors; and, a first port of the memory through the backplane. A second switch network is disposed on the second printed circuit board. The second switch network has ports coupled to: the second portion of the first plurality of directors; the second portion of the second plurality of directors; and, a second port of the memory through the backplane.
