Abstract: An administrative computer module may include a first and second Compact Peripheral Component Interconnect (CompactPCI®) chassis, where each CompactPCI chassis includes a fabric slot coupled to accept a fabric board, where the fabric slot includes an interfabric link port, where the fabric board is coupled to operate a switched fabric on a first backplane. Each CompactPCI chassis may further include a plurality of node slots coupled to accept a plurality of node boards, where each of the plurality of node slots is coupled to the fabric slot via a first pair of node links. Each of the plurality of node boards in each CompactPCI chassis is operationally redundant. Further an interfabric link may couple the fabric slot of each chassis via the interfabric link port of each chassis.
