Cache prefetching is a highly effective technique for improving I/O performance of disk array. A semantic-aware cache prefetching mechanism is designed to improve cache hit rate of disk array. The mechanism can identify some important properties of each block on the disk, and utilize that information to determine whether the block is live or dead. The allocation status (live or dead) of block is a kind of semantic information of blocks in disk array. Knowledge about semantic information of… CONTINUE READING
