Abstract

The invention discloses a distributed storage system. The system comprises multiple storage layers, a main controller and a storage monitor, wherein the multiple storage layers are used for conducting classification storage on data with different security levels, the main controller is used for receiving a data storage request sent from a client side to the main controller and establishing a storage log, and the storage monitor is used for seeking a storage layer with the same security level according to the security level of data which the main controller requests to store and performing data storage, then storing a storage path in a block chain in a form of a link, wherein the link is correlated to the storage log established on the main controller. According to the distributed storage system, secure classification storage of the data can be achieved; meanwhile, due to the existence of a data interaction and backup mechanism among storage devices in the multiple storage layers, automatic renew and backup storage of the data can be achieved, even if fault occurs in one of the storage devices, it still can be guaranteed that duplicate backups of the data are reserved in the storage device all the time, thus the permanent storage of the storage data is achieved, and not too many storage resources are occupied at the same time.

Description

technical field

[0001] The invention relates to the technical field of distributed storage, in particular to a distributed storage system. Background technique

[0002] With the in-depth development of informatization, more and more data are generated by business systems in various industries. Due to the traditional centralized storage scheme (centralized storage refers to the establishment of a specific storage area for the data to be stored, such as data Central host, store everything in this area) store all data on the data center host, if the data center host fails, the entire system cannot store and extract data, that is, the centralized storage solution is better than the distributed Data storage, data stability is low, so distributed data storage came into being.

[0003] The current distributed data storage method generally writes the data to be stored into the storage device that is not fully used; however, since the data is rarely moved after being written into th...

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0029] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0030] Such as figure 1 with figure 2 As shown, the present invention provides a distributed storage system, including:

[0031] A plurality of storage layers 100, which are used for hierarchically storing data of different security levels, and the multiple storage layers are sequentially numbered from high to low according to the security levels, wherein any storage layer is provided with several storage devices and is numbered sequentially , and the plurality of storage devices perform pairwise information exchange and pairwise data backup between adjacent storage devices ac...
