Abstract

The invention provides an electric power big-data cloud storage system achieving N-3 storage medium failure tolerance. The electric power big-data cloud storage system comprises a cloud storage control management unit, wherein the cloud storage control management unit is connected with a [ 32, 16 and 8] Reed-Muller code coding processing unit of an electric power big-data block, a writing-in communication transmission channel, a storage medium array with a rows and 32 lines, a reading-out communication transmission channel and a [32,16 and 8] Reed-Muller code decoding processing unit of the electric power big-data block, and the [ 32, 16 and 8] Reed-Muller code coding processing unit, the writing-in communication transmission channel, the storage medium array, the reading-out communication transmission channel and the [32,16 and 8] Reed-Muller code decoding processing unit are sequentially connected. According to the electric power big-data cloud storage system, the Reed-Muller code coding and decoding technique and the hash function abstract technique are adopted, any storage medium failures with the number equal to or less than 3 can be allowed to occur simultaneously, the N-3 failure tolerance is achieved, balance and optimization of the storage capacity, the failure tolerance capacity and expansibility of the electric power big-data cloud storage system is achieved, data safety is guaranteed, it is guaranteed that data have definite privacy and integrity, and therefore construction and development of the electric power big-data cloud storage system are prompted.

Description

technical field [0001] The invention is applied to systems in the electric power industry, and specifically relates to an electric power big data cloud storage system capable of allowing N-3 storage media to fail. Background technique [0002] With the continuous improvement of industrialization and informatization in modern society, data has replaced computing as the center of information computing, and cloud computing and big data are becoming a trend and trend. In turn, the demand for storage technology is getting higher and higher, including storage capacity, availability, I / O performance, data security, scalability and many other aspects. [0003] The power system data storage system is equivalent to the central brain of the power system. The failure of its storage medium unit will cause data loss, which will directly affect the safe, stable and reliable operation of power generation, power transmission, power transformation, power distribution, power consumption, and ...
