A multi-host computer system has a plurality of hosts, a plurality of slot parts, and a PCI Express link that connects the plurality of hosts with the plurality of slots. The PCI Express link connects the plurality of hosts and the plurality of slots so that a combination of them can be changed, while connects the bandwidth of the connect channel so that it can be changed. The PCI Express link connects the plurality of hosts with the plurality of slot parts via first stage and second stage switching elements. The first stage switching elements of the sets the lane assign and the number of lanes of the input/output ports of the plurality of hosts and the second stage switching elements connects the plurality of slot parts with the input/output ports of plurality of hosts so that a combination of the input/output ports and the plurality of slots can be changed.
