Abstract:

To address the problems of write amplification, long I/O path, and high access latency in distributed storage systems, an efficient SSD-based caching approach for distributed storage systems was proposed.This approach adopts read/write bypassing and lazy caching methods to manage the cache system, considers last access time and historical access frequency when performing cache replacement, and adjusts the flushing speed according to the foreground workload.It improves significantly the reading and writing performance of storage systems.

Key words: distributed storage, distributed data caching, read/write bypassing, lazy caching, replacement strategy
