Abstract

An operating store is coupled to a plurality of diverse-sized DASDs (direct-access storage devices). The allocation unit of the operating store is selected to be a submultiple of all storage capacities of the diverse storage devices, such as 2 kilobytes or 4 kilobytes. An accumulator interposed between the operating store and the storage devices accumulates data from the operating store in multiples of allocation units such that each track or allocatable storage space of the storage devices is always filled. For example, in device D1 four allocation units are stored as a block of signals, while in device D2 ten units are stored.
