ABSTRACT:
A shared storage configuration system for use in a computer system includes a plurality of processing modules and a plurality of shared storage modules. Each of the processing modules has at least a main storage unit, a central processing unit, and a connection unit for connection to a system bus. Each of the shared storage modules has a shared storage unit and a connection unit for connection to the system bus. A space inherent in the processing modules is accessible by physical addresses of the central processing units. The shared storage space is accessible either in program mode by the physical addresses of the central processing units or in direct memory access mode by relative addresses translated from the physical addresses output by the central processing units.
