【摘要】：网络存储技术发展非常快，传统以DAS、NAS、SAN存储架构为主的数据中心架构已经适应不了校园信息化的发展。因此构建一个高性能的数据中心存储系统，确保系统全天持续工作，异地容灾备份的数据中心是有必要的。 四川邮电职业技术学院是一所西南地区面向通信行业的省级示范高职院校，目前的数据中心仍是围绕服务器搭建的架构，教务管理系统等应用系统安装在一台服务器上，服务器既要运行应用系统，同时又要产生数据本地存储。虽然可以满足当前大多需求，但仍有：没有集中的存储设备，单机故障危险较高；存储空间浪费严重，数据无法实现简单安全共享；没有基于时间点的快照备份和恢复机制；各实验室地理位置分散，没能形成一个有机整体，信息孤岛无法实现数据集中传输、存储和管理。 为了解决前文中目前校园网数据中心存在的问题，本篇论文提出基于IP-SAN的存储架构解决方案。在细致深入分析IP-SAN、iSCSI技术原理的理论基础上，从存储系统架构和需求分析出发，充分考虑存储网络建成使用的业务需求，对数据中心网络的规划、设计、建设与后期测试作深入全面的分析研究。主要内容为： 首先分析了高校数据中心架构现状的问题，，探讨了存储技术的发展历程、分析和研究。当前IP-SAN作为存储技术较为热门的技术，在高校数据中心存储系统中应用也较为普遍。明确了本课题的研究内容重心在数据中心存储系统IP-SAN架构、iSCSI协议原理。 然后深入研究数据中心存储系统，以及系统硬件平台的结构、原理，采用合理的硬件系统方案设计。规划设备硬件，确定存储设备、交换机和服务器的设备型号以及数量、硬件配置。存储系统架构的硬件连接方式和网络结构。 再详细研究了存储系统的组网架构(基于IP-SAN)，完成了硬件设备选型。通过存储管理系统管理存储资源以及合理调配各项数据业务。并提供建议，涉及以后的数据中心的升级预留空间，保证了可持续性投入、应用。 最后全方位研究IP-SAN架构下的网络调试及数据业务运行过程中发现的问题和故障，剖析问题，提出解决办法，在实际应用过程里面总结归纳、积累运维经验。
[Abstract]:The development of network storage technology is very fast. The traditional data center architecture based on DAS,NAS,SAN storage architecture can not adapt to the development of campus information. Therefore, it is necessary to build a high performance data center storage system to ensure that the system continues to work all day long. Sichuan Postal and Telecommunications Vocational and Technical College is a provincial model vocational college facing the communication industry in southwest China. At present, the data center is still built around the structure of the server, the educational administration system and other application systems are installed on a server. The server not only runs the application system, but also produces local data storage. Although most of the current needs can be met, there are still: no centralized storage devices, high risk of single machine failure; serious waste of storage space, data can not achieve simple security sharing; there is no snapshot backup and recovery mechanism based on time point; The geographical location of each laboratory is scattered, which fails to form an organic whole, and the information island can not realize the centralized data transmission, storage and management. In order to solve the problems existing in the campus network data center, this paper proposes a storage architecture solution based on IP-SAN. On the basis of detailed and in-depth analysis of the theory of IP-SAN,iSCSI technology, from the perspective of storage system architecture and requirement analysis, the business requirements of storage network are fully considered, and the planning and design of data center network are given. Construction and post-testing for in-depth and comprehensive analysis and research. The main contents are as follows: firstly, this paper analyzes the current situation of the data center architecture in colleges and universities, and discusses the development course, analysis and research of the storage technology. At present, as a popular storage technology, IP-SAN is also widely used in the data center storage system of colleges and universities. The research focuses on the data center storage system IP-SAN architecture and the principle of iSCSI protocol. Then the data center storage system, the structure and principle of the system hardware platform are studied, and the reasonable hardware system scheme is adopted. Plan device hardware, determine storage device, switch and server device model and quantity, hardware configuration. The hardware connection and network structure of the storage system architecture. Then the network architecture of storage system (based on IP-SAN) is studied in detail, and the selection of hardware equipment is completed. Through the storage management system to manage storage resources and reasonable allocation of data services.
