Abstract

The invention discloses a data storage method and device. The method comprises the specific steps of obtaining current access times of data in a storage system, wherein the storage system comprises storage media of one or more storage levels, and the storage levels are associated with the read-write speed; according to the current access times of the data and the storage levels of the storage media where the data are stored, calculating a cache hit rate of the storage system; judging whether the cache hit rate equals to a preset hit rate or not; if the cache hit rate does not equal to the preset hit rate, migrating the data in the storage media, so that the cache hit rate obtained after migration equals to the preset hit rate. According to the data storage method and device, storage capacity of the storage media different in read-write speed is effectively utilized, storage efficiency of the storage system is improved, and thereby efficiency of processing data access requests is improved.

Description

technical field [0001] The present application relates to the technical field of electrical data processing, in particular to the technical field of data exchange network, and in particular to a data storage method and device. Background technique [0002] Cache memory (cache) is a memory located between a central processing unit (Central Processing Unit, CPU) and a dynamic random access memory (Dynamic Random Access Memory, DRAM). , SRAM) composition. In the storage system, the speed of the CPU is much higher than that of the memory. When the CPU directly accesses data from the memory, it has to wait for a certain period of time, and the cache can save a part of the data that the CPU has just used or recycled. If the CPU needs to use the data again Part of the data can be called directly from the cache, thus avoiding repeated access to data, reducing the waiting time of the CPU, thus improving the efficiency of the system. Distributed cache storage service can further imp...
