Title
DM-Pages: Improving Energy Efficiency of Disk Storage Systems and Cache Performance Using Deduplication-based Mixed Pages
Abstract
This paper proposes a deduplication-based mixed page strategy, called DM-Pages, to improve the energy efficiency of disk storage systems and the cache performance. DM-Pages strives to improve the cache hit rate, simultaneously reduce the number of power-state transitions of a disk storage system and keep it in a low-power state as long as possible. DM-Pages deploys three innovative techniques. It adjusts the size of huge pages dynamically to maximize the cache hit rate. Meantime, content-aware deduplication is applied to eliminate redundant cache pages, targeting to enhance cache utilization. In addition, DM-Pages incorporates a mixed page mechanism into disk energy management to save energy. Our experimental results show that DM-Pages significantly improves the energy efficiency of disk storage systems and achieves a high cache hit rate. In particular, compared with traditional disk storage systems, DM-Pages conserves 6.59 times energy and improves the cache hit rate up to 3.36 times.
