摘要: A system and method for efficiently caching metadata in a storage system. Addresses from plurality of I/O accesses to the are captured then frequency domain representation addresses is generated. The used measure randomness various applications which accessing Scores generated based on randomness, scores assigned regions logical address space. pages stored cache region space correspond. when determining evict cache. will attempt those correspond that servicing random accesses.
