Data block hierarchical storage method and device, computer equipment and storage medium

The invention discloses a data block hierarchical storage method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining the access times of each data block in a data block set stored in a storage space in a plurality of historical periods, the access times in a current period and a plurality of time attribute parameters corresponding to the data block, and carrying out heat calculation on the data blocks, judging the heat rating of each data block according to the calculated heat value of the data block and the boundary threshold of the heat rating, and migrating the target data block needing to be migrated according to the heat rating of each data block. By adopting the method and the device, the popularity rating of the data block can be accurately determined, the data block needing to be migrated is determined from the popularity rating, the data block migration is automatically carried out, the composition of the data blocks stored in different storage areas is
