Abstract

The invention belongs to the field of internet communication and provides a method for determining a data migration target. The method comprises the following steps of comparing a heat value of estimated data with a set threshold value of each storing layer, and performing local selection to obtain a local selection result; performing re-selection on the local selection result in the way of combining the residual space of each storing layer to obtain the data migration target; and after data migration is finished, updating the threshold value according to a migration result. Local selection and overall selection are combined, self-selection is performed on each storing layer, further selection is performed on the data target subjected to local selection, and the residual space of each storing layer is combined to determine the data migration target, so that the migration target can be reduced as much as possible and can adapt to the dynamic change of system load, and good storage resources can also be fully used.

Description

technical field [0001] The invention belongs to the field of Internet communication, and in particular relates to a method and a device for determining data migration objects. Background technique [0002] With the explosive growth of data, clusters that store massive amounts of data emerge as the times require. Because the amount of data stored in the cluster is large, and some have reached the PB level, there may be a large amount of data access at the same time. Therefore, whether the data storage location is reasonable directly affects the data access delay. [0003] Data migration refers to the process of moving data between different storage media. Usually, the frequency of data migration is relatively small, and the purpose is mostly related to system upgrade or data backup. However, the data migration in the hierarchical storage system occurs frequently, and its purpose is to adjust the location of the data so that the access performance of all data in the system ...
