摘要: A system having a high speed switching interface between remote buses is disclosed herein. The system includes a switch fabric to which multiple remote bus interfaces are connected. A programmable flow queue that includes multiple parallel logic flow queues is utilized for scheduling packets in accordance with protocol requirements of the remote bus interface.

摘要: 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.
