分布式云存储高可用框架研究

近年来,分布式云存储为非结构化数据的存储、处理提供了高效、廉价的解决方案,但随着业务系统对系统可用性要求的不断提高,对分布式云存储高可用框架的研究具有重要的理论价值和广阔的应用前景.论文综合分析了分布式云存储的基本理论,提出了针对智能电网设计的分布式云存储高可用框架,该框架采用双活主节点以及多服务心跳监测算法,保障在高并发读写文件操作下分布式云存储的高可用性.实验结果表明,该框架能够有效应对任意节点失效产生的系统故障.

High Availability Framework of Distribution Cloud Storage

In recent years,distribution cloud storage provides an efficient,inexpensive solution of storing and dealing with unstructured data.However,the application system continuously increases high availability requirements,so it has important theoretical value and broad application prospects in doing research on high availability framework for distributed cloud storage.This paper comprehensively analyzes the basic theory of distributed cloud storage,and it is proposed of cloud storage HA frame for smart grid which uses dual active master node technology and multi-service heartbeat monitoring algorithm to guarantee HA while high concurrent read and write file operations occurring.Experimental results show that the framework can effectively handle system failures due to any node failure.
