Abstract

The invention discloses a hierarchical storage method, system and device and a storage medium, and the method comprises the following steps: setting a hot storage pool based on a first storage disc ina distributed object storage system, and setting a cold storage pool based on a second storage disc; in response to read operation or write operation on a file, increasing the popularity value of thefile, and then reducing the popularity value of the file every other preset time; judging whether the heat value of the file in the hot storage pool is smaller than a first threshold value or not, and judging whether the heat value of the file in the cold storage pool is larger than a second threshold value or not; and in response to the heat value of the file in the hot storage pool being less than a first threshold, transferring the file to the cold storage pool, and in response to the heat value of the file in the cold storage pool being greater than a second threshold, transferring the file to the hot storage pool. According to the scheme provided by the invention, the performance of different media in the distributed storage system is effectively utilized, the performance and cost ofthe storage system are considered, and the product competitiveness is improved.

Description

technical field [0001] The present invention relates to the field of storage, and more specifically, refers to a hierarchical storage method, system, computer equipment and readable medium. Background technique [0002] A distributed object storage system is a storage cluster composed of multiple object storage servers. Distributed storage has the advantages of high reliability, high availability, fast access, and easy expansion. At present, HDD mechanical hard disks are widely used in storage systems, but as the prices of new storage media, SSDs, and NVME SSDs drop, storage systems are gradually equipped with some SSD hard disks as storage media. The performance of fast storage media is good, but the capacity is often insufficient. The HDD hard disk has a large capacity, but its performance is slightly insufficient. How to balance system performance and cost has become a problem to be solved in storage system design. Contents of the invention [0003] In view of this, t...
