Abstract: Allocation of space of peripheral storage devices 16 to host (10) processes is based upon free or unallocated space in each such device. The device, irrespective of capacity, having the largest free space is most likely to receive a next space allocation. A central record 15 in a multi-host system stores free space indications. In a disk storage device free space is indicated by the number of unallocated data storage record tracks for each such device.
