Summary:The invention discloses a hierarchical storage realization method and a system. The method comprises the following step: when any of the servers needs to access the stored data, whether the accessed data is existed in an one-level memorizer or not is judged, if not, the data to be accessed is transferred to the one-level memorizer form a two-level memorizer; and the data access of the server is realized through the one-level memorizer. According to the invention, memorizers with different access rates are adopted, the data access is realized by the faster memorizer through data transfer, and the access efficiency of a storage system is improved without affecting the normal storage of the data, thereby optimizing the storage data structure of cluster servers.
