SAC: rethinking the cache replacement policy for SSD-based storage systems

  title={SAC: rethinking the cache replacement policy for SSD-based storage systems},
  author={Zhiguang Chen and Nong Xiao and Fang Liu},
Solid-state drives (SSDs) are widely used in storage systems. However, algorithms adopted by existing operating systems generally consider the underlying devices as hard disks, and thus are rarely optimized for SSDs. In this paper, we focus on a classical research issue, the cache replacement policy, and design a new policy by taking the parallelism of SSDs into account. A typical SSD contains several parallel channels. Some channels contain more hot data, thus are busy with read requests. The… CONTINUE READING
