  • Preventing cache floods from sequential streams
    Patent number: 6823428
    Abstract: A method that avoids cache flooding when handling sequential I/O request streams in storage subsystem caches. Both on-demand and prefetched data are addressed. A mechanism is provided that makes the blocks read from the disk array, that are part of a sequential I/O request stream, minimize the evictions of potentially useful data blocks from the cache, thus avoiding the flooding of the cache by stale data.
