Abstract

The invention discloses a hot and cold data-oriented hierarchical storage system and method. The system comprises a data acquisition module, a hot and cold data judgment module and a hot and cold data migration module; the data acquisition module is used for acquiring a user data access request; the cold and hot data judgment module is used for analyzing the data access request, calculating the data temperature according to the analyzed temperature calculation related information, updating the temperature calculation related information and the data temperature, and re-packaging the temperature calculation related information and the data temperature to original data; and the cold and hot data migration module is used for monitoring the data in a hot library, migrating the hot data which does not conform to two set thresholds in the hot library into the cold storage, and dynamically adjusting the set thresholds according to the data access characteristics. According to the method, the temperature of the data is quantified on the basis of the characteristics of the data in three aspects of access time, access frequency and data relevance, and judgment of cold and hot data and separated storage of the cold and hot data are realized.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a hierarchical storage system and method for hot and cold data. Background technique [0002] The storage demand brought about by the surge in data volume continues to increase, and enterprises optimize storage space by establishing a hierarchical storage architecture. In order to improve the space utilization in the tiered storage system, the enterprise divides the data into hot data with frequent access and cold data with infrequent access, and matches the data access characteristics with the performance of storage devices to avoid cold data residing in high Storage pollution caused by the performance storage layer. The identification accuracy of hot and cold data will directly affect the data access efficiency of the hierarchical storage system. [0003] Therefore, it is of great significance to carry out research on the storage mechanism for hot and cold data. The res...
