  • Method and apparatus for allocating memory space based upon free space in diverse memory devices
    Patent number: 4528624
    Abstract: Allocation of space of peripheral storage devices to host 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 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.
