英文摘要	Flash memory has been gaining more popularity as a substitution for magnetic disk. However, due to asymmetric 10 latency, cache management policy needs to be reconsidered in systems equipped with flash. A novel buffer replacement approach named ACAR, which stands for Adaptive Cost Aware cache Replacement, is proposed in this paper to address this problem. Taking operation cost into consideration, ACAR allocates two pools for clean and dirty pages separately. In addition, dynamical pool size tuning is also performed according to TO pattern evolvement. Furthermore, hot data recognition capacity is realized in an enhanced version of ACAR. Experiments with artificial and real 10 traces demonstrate ACAR outperforms the state-of-the-art cache replacement strategies.; Computer Science, Information Systems; Computer Science, Theory & Methods; EI; CPCI-S(ISTP); 0
