  • Patent number: 8572428
    Abstract: A first controller stores externally input data to a memory of the first controller, reads data stored in the memory of the first controller and transmits the data to a second controller through a first controller bridge, detects a failure at the first controller bridge in transmission of the data. The second controller receives the data through a second controller bridge, writes the received data into a memory of the second controller, and determines whether the failure is caused by the first controller if a failure occurs in the memory controller and the second controller bridge. If a failure is detected in the first controller and the second controller and the failure is caused by the first controller, the first controller transmits the data causing the failure during transmission through the first controller bridge and the second controller receives the data through the second controller bridge.
