Abstract

Embodiments of the invention provide a data migration method and device. The method comprises the following steps of: obtaining state information of multiple storage devices; determining an emigrationdevice of to-be-emigrated data and immigration device of to-be-immigrated data from the multiple storage devices according to the state information; selecting to-be-emigrated target data from the data stored in the emigration device; and migrating the target data to the immigration device from the emigration device. On one hand, state indexes such as IOPS, throughput bandwidth and the like can besynthesized to comprehensively assess performance of the storage devices, and equipment storage files are selected from the storage devices, so that demands of different businesses are satisfied, file storage under multiple businesses is realized and the resource waste is decreased, and on the other hand, states of different storage devices can be synthesized to carry out data migration, so thatload balance between the storage devices is realized and storage performance of the storage devices is ensured.

Description

technical field [0001] The invention relates to the technical field of computer processing, in particular to a data migration method and a data migration device. Background technique [0002] In systems such as content distribution network CDN, due to business requirements, a large amount of data needs to be stored. [0003] According to business needs, different concurrency and throughput are required for storage devices. Therefore, in one device, storage devices with corresponding functions are usually configured separately. [0004] Due to the functional limitation of the storage device, it is difficult for this device to handle other services, and it is in an idle state, which easily leads to waste of resources. Contents of the invention [0005] In view of the above problems, the present invention is proposed to provide a data migration method and a corresponding data migration device that overcome the above problems or at least partially solve the above problems. ...
