    • 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.
    • 第一控制器将外部输入数据存储到第一控制器的存储器中,读取存储在第一控制器的存储器中的数据,并通过第一控制器桥将数据发送到第二控制器,在第一控制器桥传输期间检测故障 数据。 第二控制器通过第二控制器桥接器接收数据,将接收到的数据写入第二控制器的存储器,并且如果在存储器控制器和第二控制器桥中发生故障,则确定是否由第一控制器引起故障。 如果在第一控制器和第二控制器中检测到故障,并且由第一控制器引起故障,则第一控制器在通过第一控制器桥传输期间发送导致故障的数据,并且第二控制器通过第二控制器接收数据 桥。
