【摘要】：随着高校信息化建设的不断发展,高校各应用服务器数量激增,传统的数据中心面临着系统管理复杂、资源利用率低下、投资回报不佳、IT适应性低、安全控制与数据备份困难等诸多问题。如何适应业务的需要和变化,降低成本,提高IT效率成为摆在各高校数据中心面前的一大难题。本文旨在解决上述问题,利用虚拟化技术帮助高校数据中心解决IT基础设施面临的种种挑战。论文详细论述了高校数据中心虚拟化的发展状况,并对虚拟化技术的理论作了详尽的分析。在对某高校数据中心虚拟化建设需求进行仔细分析后,重点阐述了如何根据其特点和现状,利用VMware vSphere套件来实现虚拟化的部署,研制出一套适合某高校数据中心虚拟化建设方案,提高信息共享率,消除“信息孤岛”,保持数据的完整性和准确性。数据中心虚拟化包括服务器虚拟化、网络虚拟化、存储虚拟化三部分。通过将服务器虚拟化,可以有效提高其资源利用率,加快部署的速度,提升管理维护的便捷度,并且可以利用VMotion动态迁移来提高服务响应能力。通过将网络虚拟化,在提高各个虚拟网络之间的安全性和可控性的同时,优化网络的基础架构,提升带宽容量和网络速度、降低网络投资成本。通过存储虚拟化,可以有效提高磁盘利用率,加快故障恢复速度,实现在一个SAN网络上不同的服务器之间共享各类数据资源,为之后实现HA功能、DRS功能铺平了道路。
[Abstract]:With the continuous development of information construction in colleges and universities, the number of application servers in colleges and universities has increased sharply. Traditional data centers are faced with complex system management, low utilization of resources, poor investment returns and low IT adaptability. Many problems such as security control and data backup are difficult. How to adapt to the needs and changes of business, reduce costs and improve IT efficiency has become a big problem in front of data centers in colleges and universities. This paper aims to solve the above problems and use virtualization technology to help university data centers solve the challenges of IT infrastructure. This paper discusses the development of data center virtualization in colleges and universities in detail, and analyzes the theory of virtualization technology in detail. After analyzing the requirement of virtualization construction in a certain university data center, the paper focuses on how to use VMware vSphere suite to deploy virtualization according to its characteristics and present situation. A set of virtualization scheme suitable for a university data center is developed to improve the information sharing rate, eliminate the "information island", and maintain the integrity and accuracy of the data. Data center virtualization includes server virtualization, network virtualization and storage virtualization. By virtualizing the server, it can effectively improve the resource utilization, speed up the deployment, improve the convenience of management and maintenance, and use the dynamic migration of VMotion to improve the service response ability. By virtualizing the network, we can improve the security and controllability of each virtual network, optimize the network infrastructure, increase the bandwidth capacity and network speed, and reduce the network investment cost. Through storage virtualization, the disk utilization can be improved, the recovery speed can be quickened, and all kinds of data resources can be shared among different servers on a San network, which paves the way for the later realization of HA function and DRS function.
