Abstract

The invention provides a method for determining the data migration time and is applicable to the field of Internet communication. The method comprises the following steps that double threads are started, and the primary storage space use rate and the data migration period in a hierarchical storage system are respectively monitored; the double threads regularly judge whether the data migration conditions are met, if not, the judgment is carried out after the same time is waited until the data migration conditions are met, and if so, the data migration is executed. The migration period can be regulated according to different migration conditions, and the dynamic change of loads in the cluster can be met, so the primary storage space in the hierarchical storage system can be fully utilized, a system is also enabled to regulate the data position in time, and the visit performance of the system reaches the optimum.

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 the timing of data migration. 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 movement of data between different storage media. To complete data migration, the system needs to consume certain resources (including hardware resources, bandwidth, etc.). [0004] In a cluster that stores massive amounts of data, situations that require data migration mainly include system upgrades, data backup / recovery, and dynamic adjustment of data in hierarchical s...
