Problems solved by technology

However, when the amount of data increases and IO requests surge, the processing of the request message queue by the central scheduling server will cause significant delays, thus greatly affecting the performance of the storage system
Moreover, when the storage system is attacked or affected by other external conditions, as long as the central scheduling server fails, the entire storage system will be paralyzed

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The invention provides a data storage method, such as figure 2 shown, including:

[0028] S201. Divide multiple storage devices into blocks, and connect the blocks to form at least one blockchain; each storage device is a node of the blockchain;

[0029] S202. When a request for writing data is received, select the optimal node to write the data, and at the same time add the record information of the data written by the optimal node to the public reco...

Abstract

The invention discloses a data storage method and data storage system. The data storage method comprises the following steps: dividing a plurality of storage devices into different blocks, and connecting the blocks to form at least one block chain; taking the storage devices as nodes of the block chains; and when receiving a data writing request, selecting an optimal node to write data, and meanwhile adding recording information of an optimal node writing data on a public record book of all the nodes in the block chains. By the data storage method and the data storage system, a centralized storage mode is omitted, traditional data storage is distributed, dispatching of data does not need to be implemented in a data center, and is implemented on the different nodes actually, the labor management cost is saved, semiautomatic storage management is realized, data reading and writing every time can be recorded on the public record book, the changing track of the data can be traced, therefore, the data are attacked difficultly, the data are effectively prevented from being tampered when stored, and the safety of the data is greatly improved.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a data storage method and a data storage system. Background technique [0002] At present, the traditional storage server architecture needs to manage the data reading and writing of each storage node and storage device through a central scheduling server. Such as figure 1 As shown, when the storage device generates IO data, the IO data is written into the storage only after first transmitting the data information to the central dispatching server and waiting for the central dispatching server to generate a return message. However, when the amount of data increases and IO requests surge, the processing of the request message queue by the central scheduling server will cause significant delay, thus greatly affecting the performance of the storage system. Moreover, when the storage system is attacked or affected by other external conditions, as long as the central scheduling server fa...
