Abstract:
The embodiments provide a backplane for a storage device that is readily extensible to accommodate a range storage media. In some embodiments, the controller is provided on a motherboard. In order to support a different numbers of bays, various management riser cards are provided on the motherboard to expand the capacity of the backplane while still using the same controller. The backplane supports a serial addressing scheme and shift registers to identify ports connected to the storage device controller to allow for different numbers of storage media to be connected to the motherboard. This allows the storage device controller to use the same addressing protocol and software for any number of drive bays.
