ABSTRACT:
A processor module generates a data write request and sends data specified thereby to each of two data buffers respectively provided in two data storage units, each having a data storage device, such as a magnetic disc device. When the data has been completely written into each of the data buffers, a write completion response is sent back to the processor module from each of the data storage units. When the processor module has received the write completion responses from the data storage units, it recognizes that the data write request has been completed.
