A centralized control unit for use in a multisystem data processing configuration to provide dynamic access to shared and non-shared peripheral subsystems is disclosed. This unit, known herein as a subsystem access unit (SAU) is able to remotely control one or more system\s accessibility to peripheral subsystem\s from a central location. It is able to provide this control with the capability of either allowing a peripheral subsystem to be concurrently accessed by more than one system or forcibly ensuring that the peripheral subsystem is exclusively accessible by only a single system.

A central controlling unit, for use with a plurality of data processing systems, none, some, or all of which are capable of being partitioned into a further plurality of separate entities, having the characteristics of a complete data processing system and a plurality of subsystem interface connections, said central controlling unit comprising: enabling/disabling connection means connected to said plurality of subsystem interface connections for dynamically enabling/disabling, from a central location, said plurality of subsystem interface connections to selected entities and/or systems; and means coupled to said enabling/disabling connection means for maintaining these enabled/disabled interconnections for as long as desired from undesired appropriation; and storage means commonly connected to said enabling/disabling connection means and to said means for maintaining these interconnections, said storage means having residual information stored therein to cause various subsystem interconnections in response to corresponding system command signals.
