【摘要】：近年来,高校的信息化建设发展迅猛,各类业务系统相继建成,在教学、科研、管理、生活等方面发挥了举足轻重的作用。但由于缺乏统一规划,众多的业务系统带来了服务器数量的剧增,高校数据中心面临着资源利用率不足、资源调配不灵活、可扩展性差、管理难度大、高能耗等诸多挑战。如何改变数据中心存在的上述问题,已成为当前数字化校园建设的一项重要内容。虚拟化技术作为云计算时代背景下快速发展的一项技术,已经引起了国内外高校的高度关注。本文在研究虚拟化及相关技术的基础上,通过对浙江科技学院数据中心服务器应用状况的监测和分析,选用了VMware vSphere虚拟化软件,设计出一套适合高校数据中心服务器虚拟化建设的方案并将其应用到浙江科技学院数据中心,取得了比较满意的效果。通过对数据中心服务器进行虚拟化整合,大大减少了服务器数量,降低了数据中心能耗,节约了投资成本,减轻了管理难度。应用VMware vMotion、VMware DRS和VMware HA等技术,实现了集群内的所有虚拟机资源统一分配调度,按业务需求提供所需的资源,将资源利用率从原先的低于10%提高到50%以上。虚拟机的在线实时迁移,既保障了服务的延续性,又避免了单点故障的发生。此服务器虚拟化方案不仅解决了传统数据中心存在的问题,而且还具备灵活的扩展能力,适应了信息化长期发展的需求。对高校数据中心资源整合具有一定的参考价值和指导意义。
[Abstract]:In recent years, the information construction of colleges and universities has developed rapidly, and various kinds of business systems have been built one after another, which play an important role in teaching, scientific research, management, life and so on. However, due to the lack of unified planning, Many business systems have brought a sharp increase in the number of servers. The university data center is faced with insufficient utilization of resources, inflexible deployment of resources, poor scalability, and great difficulty in management. How to change the above problems of data center has become an important content of the current digital campus construction. Virtualization technology as a rapid development in the cloud computing era technology, It has attracted the attention of colleges and universities both at home and abroad. Based on the research of virtualization and related technologies, this paper selects VMware vSphere virtualization software through monitoring and analyzing the application of data center server in Zhejiang Institute of Science and Technology. A set of virtualization scheme for data center server in colleges and universities is designed and applied to data center of Zhejiang Institute of Science and Technology, and satisfactory results are obtained. Through the virtualization integration of data center server, the number of servers is greatly reduced, the energy consumption of data center is reduced, the investment cost is saved, and the management difficulty is alleviated. The technology of VMware vMotionVMware DRS and VMware HA is applied. All the virtual machine resources in the cluster are distributed uniformly, and the required resources are provided according to the business requirements, and the utilization ratio of the resources is raised from 10% to more than 50%. The on-line real-time migration of virtual machines ensures the continuity of services. The single point fault is avoided. This server virtualization solution not only solves the problems existing in the traditional data center, but also has the flexibility to extend, It meets the needs of the long-term development of information technology and has a certain reference value and guiding significance for the integration of data center resources in colleges and universities.
