Abstract
Abstract A multiprocessing computer system with data storage array systems allowing for linear and orthogonal expansion of data storage capacity and bandwidth by means of a switching network coupled between the data storage array systems and the multiple processors. The switching network provides the ability for any CPU to be directly coupled to any data storage array. By using the switching network to couple multiple CPU's to multiple data storage array systems, the computer system can be configured to optimally match the I/O bandwidth of the data storage array systems to the I/O performance of the CPU's.
