A secondary storage facility including magnetic tape, disk or drum units or other sequential access storage units. Each storage unit or drive connects to a controller by means of a device bus with asynchronous and synchronous paths. Status and controller information is coupled between the controller and a selected drive unit asynchronously over the asynchronous bus. Actual data transfers occur between the controller and a drive over the synchronous bus and between other units in the system and the controller using direct memory access or equivalent data transfers.
