Abstract
An I/O equipment sharing system includes CPUs, a plurality of route complexes coupled to the CPUs, upstream PCI Express-bridges coupled to the route complexes, downstream PCI Express-bridges coupled to the upstream PCI Express-bridges through a network, and I/O equipment coupled to the downstream PCI Express-bridges. In the above configuration, the I/O equipment are shared between the CPUs using the identifiers of the network (for example, Ethernet VLAN IDs), the identifiers are set so that they do not overlap between the respective CPUs and necessary I/O equipment is set to a set identifier. Further, an identifier is set to a plurality of the same I/O equipment required by the respective CPUs.
