【摘要】：信息化时代,高职院校在教学、科研、管理、实训等方面的工作都依托于校园网,校园网已成为高职院校投入重点。而数据中心系统作为校园网的重要组成部分,其地位不言而喻。网络中大部分网络应用和服务都有赖于数据中心系统提供,数据中心系统已俨然成为校园网的核心,其发展水平将直接影响高职院校的信息化建设水平。四川托普信息技术学院是一所以IT专业为主的高职院校,其数据中心系统采用传统“奠基式向上支撑”的集中架构模式,网络应用和物理服务器之间耦合度高。随着网络业务种类和业务量的不断丰富和增加,在面对日益增长的庞大数据和海量服务时,这种结构已显得力不从心。在资源利用率、能耗、QoS、可靠性、经济性、可管理性等方面暴露出诸多缺点,特别是设备利用率低下表现的尤为明显。根据对项目的实地考察与测试,非峰值时期主要服务器的CPU、内存等资源利用率普遍低于30%。这种架构模式已经严重影响了四川托普学院信息化平台建设工作的开展。在此背景下,利用当前先进的IT技术对该数据中心系统进行升级改造就显得尤为迫切。云计算技术是当前IT行业新兴的技术也是未来IT发展的方向之一,它将传统IT资源通过虚拟化技术进行整合,形成资源池---“云”。将云里的资源进行人为分配,并通过网络以按需方式为用户提供计算、存储、网络等相关IT服务。其在可靠性、QoS、可管理性、能耗、设备利用率、伸缩性等方面具有极大的优势。依托虚拟化和云计算技术对四川托普学院集中式数据中心系统进行改进,将极大提升其综合性能,将为四川托普学院信息化建设带来新的动力。本文利用H3C CAS虚拟化云计算管理平台,对四川托普信息技术职业学院现有数据中心系统进行升级改造,详细阐述了数据中心系统虚拟化改造的一般思路和实施方法。并对H3C CAS云计算平台缺乏对管理节点(CVM节点)的运行监控手段这一薄弱环节进行了分析,有针对性地设计了解决方案:在Linux环境下设计基于UDP协议的心跳监测程序,完成对CVM节点的动态监测,以提升系统运行的稳定性。接着为改造后的数据中心系统设计了严谨的测试对比实验,以测试项目实施前后关键业务应对突发的海量访问的能力。最后从多方面对改造后的项目进行了详细的效能分析。
[Abstract]:In the information age, the work of higher vocational colleges in teaching, scientific research, management and practical training all rely on the campus network, which has become the focus of investment in higher vocational colleges. The data center system as an important part of the campus network, its status is self-evident. Most of the network applications and services depend on the data center system. Data center system has become the core of the campus network, and its development level will directly affect the level of information construction in higher vocational colleges. Top Information Technology College in Sichuan is a higher vocational college with IT specialty as the main subject. Its data center system adopts the traditional "foundation up support" centralized structure mode, and the coupling degree between network application and physical server is high. With the continuous enrichment and increase of network service types and services, this structure has been unable to cope with the increasing data and services. There are many disadvantages in resource utilization, energy consumption, QoS, reliability, economy, manageability and so on, especially the low utilization ratio of equipment. According to the field inspection and test of the project, the utilization ratio of CPU, memory and other resources of the main server in the non-peak period is generally lower than 30%. This structure model has seriously affected the construction of information platform of Sichuan Topp College. Under this background, it is urgent to upgrade the data center system by using the current advanced IT technology. Cloud computing technology is one of the emerging technologies in the current IT industry and one of the future IT development directions. It integrates the traditional IT resources through virtualization technology to form the resource pool-"cloud". The resources in the cloud are allocated artificially, and the computing, storage, network and other related IT services are provided to users on demand through the network. It has great advantages in reliability, QoS, manageability, energy consumption, equipment utilization, scalability and so on. Relying on virtualization and cloud computing technology to improve the centralized data center system of Sichuan Topp College will greatly improve its comprehensive performance and will bring new impetus to the information construction of Sichuan Topp College. This paper uses H3C CAS virtualization cloud computing management platform to upgrade the existing data center system in Sichuan Topp Vocational College of Information Technology, and expounds in detail the general ideas and implementation methods of data center system virtualization transformation. The weak link that H3C CAS cloud computing platform lacks monitoring means to manage node (CVM node) is analyzed, and the solution is designed: design heartbeat monitoring program based on UDP protocol in Linux environment, The dynamic monitoring of CVM nodes is completed to improve the stability of the system. Then a rigorous test contrast experiment is designed for the reconstructed data center system to test the ability of the key business to deal with the sudden mass access before and after the implementation of the project. At last, the efficiency of the project is analyzed in detail from many aspects.
