摘要： The present invention describes a method and system for interfacing a plurality of device controllers to an array of data storage devices by serial connection. The device controllers are coupled to a serial interface by a bus and the devices of the storage array are coupled to the serial interface by a serial connection. The serial interface receives controller signals through the bus and multiplexes the signals onto the serial connections of the storage array. Arbitration between the various device controllers seeking access to the storage array is resolved through bus protocol and through drive based reserve/release registers in the serial interface processor.
