Abstract: In a multiunit data processing system, such as a mul- ticontrol unit peripheral data storage system, a least busy one of the units (17) requests work to be done from a busier unit. The busier unit, a work sending unit, supplies work to the work requesting or least busy unit. Work thresholds in the respective units determine when work is to be requested or transferred. In a data storage environment, the transferred work consists of data transfers to be achieved usually asynchronously to connected host activities, such as data transfers between a backing (16) and a front store (40) in a data storage hierarchy.
