【摘要】：企业数据不断增长,高并发、大容量、非结构化数据存储需求持续增加,传统架构存储系统因在带宽、扩展性等方面的限制,已无法适应这种需求的变化。集群NAS存储系统因具有独立升级、线性扩展(容量增加不会带来性能瓶颈)的特性优势,正在高性能计算、动漫渲染、广播电视、地质勘探等越来越多的领域应用中成为传统架构存储产品的替代品。集群是由若干台计算机构成的一种松散耦合的计算节点集合,这些计算节点协同工作,对外提供服务。按照集群的功能特点,可以将集群分为高性能集群HPC、高可用集群HAC和负载均衡集群LBC。集群NAS存储系统是指构建在高性能、高可用或高负载均衡的集群基础上,对外提供NAS (NFS/CIFS)服务的存储系统。本文在研究集群NAS存储系统的主流技术架构、关键技术和当前主要的集群文件系统的基础上,提出了开发一款集群NAS存储系统的设计思路,即开发一款基于开源软件的,RAIN技术架构的软硬件均高度模块化的集群NAS存储系统。在该设计思路的指导下,完成了集群NAS存储系统整体架构设计、硬件平台开发和集群NAS存储系统管理软件开发等一系列设计开发工作。对所实现的集群存储系统的功能、性能及稳定性等方面进行了客观的评测,并对该系统的典型应用案例进行了深入分析。最后,对所实现的集群NAS存储系统进行了分析总结,指出当前系统所存在的不足,并制定完善改进计划。
[Abstract]:Enterprise data is growing, high concurrency, large capacity, unstructured data storage requirements continue to increase, the traditional architecture storage system in bandwidth, scalability and other constraints, can not adapt to this demand changes.The cluster NAS storage system has the advantage of independent upgrade, linear expansion (capacity increase does not bring performance bottlenecks), is high performance computing, animation rendering, radio and television,Geological exploration is becoming a substitute for traditional architecture storage products in more and more applications.Cluster is a loosely coupled set of computing nodes composed of several computers. These nodes work together to provide services to the outside world.According to the functional characteristics of the cluster, the cluster can be divided into high performance cluster HPCs, high availability cluster HAC and load balancing cluster LBCs.Cluster NAS storage system is a storage system that provides NAS / NFS / CIFS service on the basis of high performance, high availability or high load balance.On the basis of studying the main technology architecture, key technology and main cluster file system of cluster NAS storage system, this paper puts forward the design idea of developing a cluster NAS storage system.That is to develop a cluster NAS storage system which is based on open source software and high modularization of hardware and software.Under the guidance of this design idea, a series of design and development work has been completed, such as the overall architecture design of cluster NAS storage system, the development of hardware platform and the development of management software of cluster NAS storage system.The function, performance and stability of the cluster storage system are evaluated objectively, and the typical application cases of the system are analyzed.Finally, the paper analyzes and summarizes the cluster NAS storage system, points out the shortcomings of the current system, and formulates the improvement plan.
