It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent References 3789365 Parallel requestor priority determination and requestor address matching in a cache memory system Post-write address word correction in cache memory system Multiplexed directory for dedicated cache memory system Cache/disk subsystem trickle Cache/disk subsystem Synchronizing buffered peripheral subsystems to host operations Multiprocessor system with cache/disk subsystem with status routing for plural disk drives Cache/disk subsystem with load equalization Cache/disk subsystem with tagalong copy AbstractInitialization time of a peripheral storage subsystem is reduced. Each subsystem includes a cache store plus a back store having a plurality of DASD storage devides. Storage locations in the cache store are initially allocated for an index table for other subsystem control structures, track buffers, and a limited number of data storing record slots. Limiting the allocation of record slots reduces initialization time. The number of record slots initially allocated is determined by a maximum allowable system initialization time, a total number of subsystem devices to be initialized and the time required to initialize each record slot. | |
