Abstract:
1. A multi-node system including a plurality of nodes and a plurality of internodal crossbar switches each having a data switch for transmitting transfer data from a node to a node of transfer destination, and making a data transfer between the nodes via the internodal crossbar switches, wherein, if a fault occurs in the data switch of one of the internodal crossbar switches, the system is configured to make data transfer between the nodes via any other internodal crossbar switch than the internodal crossbar switch having the data switch where the fault occurs, without employing the crossbar switches in a redundant arrangement, wherein in the multi-node system, a number of said plurality of nodes is equal to a number of said plurality of internodal crossbar switches, and wherein, when there is no fault in the data switch of any of the internodal crossbar switches, the data transfer between the nodes is made via all the internodal crossbar switches.
