Abstract
A cache/disk subsystem includes a storage control unit, a relatively low capacity high speed cache store, and a higher capacity slower memory such as a plurality of disk drive devices. The storage control unit controls the subsystem to transfer from the cache store to the disk drive devices segments of data which have been modified while resident in the cache store and insures that space will be available in the cache store for new data if a particular operation requires that new data be transferred from a disk to the cache store for use. The subsystem may include plural storage control units and any of them may control the transfers of segments of data to the disks.
