A method and system for producing 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 has a plurality of first directors, a plurality of second directors, and a global memory. The method includes: providing a backplane having slots adapted to have plugged therein a plurality of printed circuit board. The printed circuit boards include: a plurality of first director boards having the first directors; a plurality of second printed circuit boards having the second directors; a plurality of memory printed circuit boards providing the global memory; a plurality of dummy first director boards having first jumpers; a plurality of dummy second director boards having second jumpers; a plurality of dummy memory boards having third jumpers. The method includes wiring the backplane to effect a connection among the first, second and third jumpers to interconnect the first plurality of director to the host computer/server, the plurality of second plurality of directors to the bank of disk drives and the global memory to the first plurality of directors and to the second plurality of director. The method and system allows the same wired backplane to be used with systems having a different number of memory and director boards and still enable dual-write and redundancy to the global memory.
