Abstract
A system interface includes a plurality of first director boards. Each one of the first director boards has a plurality of first directors and a crossbar switch having input/output ports coupled to the first directors on such one of the first director boards and a pair of output/input ports. The system interface also includes a plurality of second director boards. Each one of the second directors boards has a plurality of second directors and a crossbar switch having input/output ports coupled to the second directors on such one of the second director boards and a pair of output/input ports. A data transfer section is provided having a cache memory. The cache memory is coupled to the plurality of first and second directors. A message network is operative independently of the data transfer section. The message network includes a pair of message network boards. Each one of such message network boards has a switching network having a plurality input/output ports. Each one of such pair of input/output ports is coupled to a corresponding one of the pair of output/input ports of the crossbar switches of the plurality of first director boards and the plurality of second director boards.
