Abstract:
1. A data relay device that relays data from a plurality of adapters to a controller including a processor, the data relay device comprising: a monitoring unit that monitors a destination address of data received from an adapter among the adapters; a judging unit that judges whether the data is appropriate when the destination address matches with an address that corresponds to an interruption process to be performed by the processor; a transmitting unit that transmits the data to the controller only when the data is judged appropriate by the judging unit; a first notifying unit that notifies the adapter transmitting the data that the data is inappropriate to cause the adapter to shut down voluntarily when the data is not judged appropriate by the judging unit; and a second notifying unit that notifies the controller that the data is inappropriate to cause the controller to shut the adapter down forcibly when the data is not judged appropriate by the judging unit and the adapter has not shut down voluntarily.
