Abstract

A distributed data storage method, control device and system, the method comprising: dividing data to be stored into m2 data blocks A (101); according to B generating a first checking block set C (102); wherein D; according to E generating a second checking block set F corresponding to the data to be stored; according to G generating a third checking block set H corresponding to the data to be stored; and respectively sending the m2 data blocks and 2m + 1 checking blocks to different storage devices and storing the same therein (105). Since each checking block is linearly associated with m data blocks, and the data blocks and checking blocks are respectively stored in different storage devices, multiple failed blocks can be restored with a reduced recovery cost.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data storage, and in particular to a distributed data storage method, control device and system. Background technique [0002] The explosive growth of data makes the scale of the storage system continuously increase. The distributed network storage system adopts a scalable system structure, stores the data in multiple independent storage devices, uses multiple storage devices to share the storage load, and utilizes the control device Positioning and storing information not only improves the reliability, availability and access efficiency of the system, but also is easy to expand, thus being widely used. figure 1 It is a distributed storage system architecture diagram, such as figure 1 As shown, the distributed storage system is composed of multiple devices, each of which is a computer device that can operate independently, and each device can be interconnected through a network ...
