Abstract
A controller for use in a data processing system for coupling a direct access storage element to the system. The controller contains a control path for routing control information from the system to various circuits in the controller and designated storage elements to enable a transfer of data stored on the medium over a data path in the controller. The controller data path also couples the medium to the system and includes a switching network which permits the data to be selectively coupled to or from one of two separate system buses. Control information routed to the controller identifies the system to be involved in a transfer and routing circuits in the controller provide the connection between the controller and designated systems.
