Data storage method and device based on multiple storage devices

Abstract

The invention discloses a data storage method and device based on multiple storage devices, the magnitude of to-be-stored data capable of being stored by the multiple storage devices at least comprises two types. The method comprises the steps that when the to-be-stored data is received, determining the data magnitude of the to-be-stored data; and determining a target storage device corresponding to the to-be-stored data according to the data magnitude of the to-be-stored data and the storage magnitude interval of each storage device, and writing the to-be-stored data into the corresponding target storage device. According to the method, the available storage spaces of the storage devices are divided into at least two storage magnitude intervals, when the to-be-stored data is received, the target storage device corresponding to the to-be-stored data is determined according to the data magnitude of the to-be-stored data, and the to-be-stored data is written into the corresponding target storage device, so that the parallel storage capacity of the storage devices is improved; and when a single storage device fails, the to-be-stored data can be allocated to other storage devices, so that the system error-tolerant rate is high.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a data storage method and device based on multiple storage devices. Background technique [0002] Storage devices include Blu-ray disc libraries, tape libraries, etc. The method of using storage devices for storage and archiving is to use archiving and backup software to write data into the cache, call the manipulator to operate, and load the specified disc cartridge (or tape) to the optical drive (or tape) drive), burn the cached data into the ios9660 file system (or write it to the tape through Tar), and complete the data archiving. [0003] The archiving storage method in the related art is to store the data to be stored in the corresponding storage device according to the order of use of the storage devices when receiving the data to be stored, and switch to the next storage device when the space used by one storage device is exhausted Complete the storage operation of the ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the disadvantages in the prior art that when the space used by a storage device is nearly exhausted, switching to the next storage device for storage leads to a long waiting time for subsequent data to be stored and low storage efficiency, thereby Provide a data storage method, device and computer equipment based on multiple storage devices
