IMPLEMENTING HARDWARE ACCELERATOR FOR STORAGE WRITE CACHE MANAGEMENT FOR MANAGING CACHE LINE UPDATES FOR WRITES, READS, AND DESTAGES IN STORAGE WRITE CACHE

摘要

A method and controller for implementing storage adapter enhanced write cache management, and a design structure on which the subject controller circuit resides are provided. The controller includes a hardware write cache engine implementing hardware acceleration for storage write cache management. The hardware write cache engine performs cache line updates for writes, reads, and destages from storage write cache substantially without firmware involvement for greatly enhancing performance.
