Abstract:
1. A method for providing a data storage system for transferring data between a host computer/server and a bank of disk drives through a system interface, such system interface having a plurality of first directors, a plurality of second directors, and a global memory, comprising: providing a backplane having slots adapted to have plugged therein a plurality of printed circuit boards, such printed circuit boards comprising: a plurality of first printed circuit 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; wiring the backplane to effect a connection among the first, second and third jumpers to interconnect the first directors to the host computer/server, the second directors to the bank of disk drives, and the global memory; to the first directors and to the second directors; wherein the wiring connects the plurality of memory printed circuit boards to the first directors and the second directors to enable each one of the first directors and the second directors access to the global memory; and wherein the wiring connects the plurality of first printed circuit boards to the memory printed circuit boards in a point-to-point configuration and connects the second printed circuit boards plurality of director boards to the memory printed circuit boards in a point-to-point configuration.
