摘要：The present invention provides an information processing device allowing continued use of input/output processors even if a non-recoverable major fixed failure takes place in a common control unit connected to a plurality of input/output processors or a common control unit is to be replaced while the system is running. In an information processing device, a plurality of input/output processors is connected to a system control unit via a plurality of common control units. The plurality of common control units and at least one instruction processor are connected to a main memory device via the system control unit. A plurality of information paths are provided so that each input/output processor is connected, to at least two different common control units.
