Cache acceleration technology can take advantage of the high performance of random access of solid state drives (solid state disks,SSD) to improve the random read and write performance of mechanical hard drives. Traditional cache acceleration technology is difficult to adapt to the needs of hot data access such as high concurgency and intermittent frequent access under the background of big data. In order to improve the overall performance of the cache, a cache strategy based on the virtual storage layer (The cache strategy based on the virtual storage layer, CVSL) is proposed, which combines the caching technology with the hierarchical storage technology to realize the cache control based on the data logic layering through thermal statistics and data logical migration. Experimental results show that compared with the traditional caching strategy, the random reading and writing performance of CVSL strategy has improved by 9-10%, no obvious fluctuations have been seen, and the cache hit rate has a good effect, and the expected design target has been achieved.
