Data processing method and device

Abstract

The embodiment of the invention provides a data processing method and a data processing device. The method comprises the following steps of: judging whether the access frequency of data on a first virtual magnetic tape is lower than an access frequency threshold value corresponding to the first virtual magnetic tape or not; and if the access frequency of the data on the first virtual magnetic tape is lower than the access frequency threshold value corresponding to the first virtual magnetic tape, transferring the data on the first virtual magnetic tape onto a second virtual magnetic tape or a physical magnetic tape, and updating a mapping relationship between the magnetic tapes and logic unit numbers (LUNs), wherein the first virtual magnetic tape is arranged in a virtual magnetic tape library, the second virtual magnetic tape is arranged in the virtual magnetic tape library, an attribute value of the second virtual magnetic tape is lower than that of the first virtual magnetic tape, and an attribute value of the physical magnetic tape is lower than that of the first virtual magnetic tape. The data is processed by utilizing the mapping relationship between the magnetic tapes and the LUNs without setting a third-party software system, so that the data processing efficiency is improved, hardware equipment is reduced, and the cost is lowered.

Description

technical field [0001] Embodiments of the present invention relate to storage technologies, and in particular, to a data processing method and device. Background technique [0002] Storage devices can be divided into hard disks and magnetic tapes, etc. Among them, hard disks are suitable for fast response access occasions, while magnetic tapes are suitable for long-term storage and fast sequential reading and writing of large files, and tapes also have low cost and low energy consumption. , The advantages of easy transportation, so the hard disk and magnetic tape can be combined into a storage system for storing data. [0003] In the prior art, a common online database formed by high-speed hard disks, a virtual tape library formed by low-speed hard disks, a physical tape library formed by physical tapes, and a third-party software system are mainly combined into a storage system. The cost and energy consumption of the data are high; the virtual tape library stores data that...
