ABSTRACT:
Control methods are provided for a storage device controller system including first and second storage device controllers. Each of the first and second storage device controllers includes an I/O control module for communicating with a respective storage device storing data in a Fixed Block Architecture recording format, and a respective communications control module for receiving data requests for a respective storage device. The first storage device controller transmits a command to the second storage device controller if a data read request is received for data stored on storage device for the second storage device controller, and subsequently transmits the data that are read out from the storage device by the second storage device controller.
