远程容灾系统设计框架

随着数据信息越来越成为核心资源和社会对数据存储安全的迫切需求,以及网络存储技术的快速发展,远程容灾系统成为当前工业界和学术界共同关注的热点。但当前对容灾系统的研究主要集中于具体技术的研究开发和实现优化,而从系统的角度研究如何将这些容灾技术整合起来组成有机的远程容灾系统,以及对远程容灾系统进行评价和设计优化,则缺少足够的技术支持。文章提出了远程容灾系统统一结构框架,并对系统的组成,主要设计空间和设计参数进行了总结和分析,进而给出了远程容灾系统形式化模型RDS,分析了系统的组成、设计参数、设计目标及限定条件。

Survey of Remote Disaster Recovery System and its Formal Design Model

with the trend that Data information has become the most important resource and with the rapid development of Network Storage technology,Research on Remote Disaster Recovery System has become the focus of both industry and Academy.But at present,most of the research concentrates on the design,implementation and optimization of certain concrete technology related with Remote Disaster Recovery System.There is rarely any research which considers when and how to use these technologies or combine them to design the whole cost-performance efficient system or evaluate the Remote Disaster Recovery System from a system's perspective.This paper proposes the unified Remote Disaster Recovery System architecture followed by the analysis and summary of the system's components,main technologies,designing space and designing parameters.Finally gives a formal design model of Remote Disaster Recovery System with explanations of the model's elements such as system architecture,value set of designing parameters,constrained conditions,designing objectives.This model can be used to design automatic generated system alternatives and to evaluate the performance and cost of Remote Disaster Recovery Systems
