【摘要】：信息化時(shí)代,高職院校在教學(xué)、科研、管理、實(shí)訓(xùn)等方面的工作都依托于校園網(wǎng),校園網(wǎng)已成為高職院校投入重點(diǎn)。而數(shù)據(jù)中心系統(tǒng)作為校園網(wǎng)的重要組成部分,其地位不言而喻。網(wǎng)絡(luò)中大部分網(wǎng)絡(luò)應(yīng)用和服務(wù)都有賴于數(shù)據(jù)中心系統(tǒng)提供,數(shù)據(jù)中心系統(tǒng)已儼然成為校園網(wǎng)的核心,其發(fā)展水平將直接影響高職院校的信息化建設(shè)水平。四川托普信息技術(shù)學(xué)院是一所以IT專業(yè)為主的高職院校,其數(shù)據(jù)中心系統(tǒng)采用傳統(tǒng)“奠基式向上支撐”的集中架構(gòu)模式,網(wǎng)絡(luò)應(yīng)用和物理服務(wù)器之間耦合度高。隨著網(wǎng)絡(luò)業(yè)務(wù)種類和業(yè)務(wù)量的不斷豐富和增加,在面對(duì)日益增長的龐大數(shù)據(jù)和海量服務(wù)時(shí),這種結(jié)構(gòu)已顯得力不從心。在資源利用率、能耗、QoS、可靠性、經(jīng)濟(jì)性、可管理性等方面暴露出諸多缺點(diǎn),特別是設(shè)備利用率低下表現(xiàn)的尤為明顯。根據(jù)對(duì)項(xiàng)目的實(shí)地考察與測試,非峰值時(shí)期主要服務(wù)器的CPU、內(nèi)存等資源利用率普遍低于30%。這種架構(gòu)模式已經(jīng)嚴(yán)重影響了四川托普學(xué)院信息化平臺(tái)建設(shè)工作的開展。在此背景下,利用當(dāng)前先進(jìn)的IT技術(shù)對(duì)該數(shù)據(jù)中心系統(tǒng)進(jìn)行升級(jí)改造就顯得尤為迫切。云計(jì)算技術(shù)是當(dāng)前IT行業(yè)新興的技術(shù)也是未來IT發(fā)展的方向之一,它將傳統(tǒng)IT資源通過虛擬化技術(shù)進(jìn)行整合,形成資源池---“云”。將云里的資源進(jìn)行人為分配,并通過網(wǎng)絡(luò)以按需方式為用戶提供計(jì)算、存儲(chǔ)、網(wǎng)絡(luò)等相關(guān)IT服務(wù)。其在可靠性、QoS、可管理性、能耗、設(shè)備利用率、伸縮性等方面具有極大的優(yōu)勢。依托虛擬化和云計(jì)算技術(shù)對(duì)四川托普學(xué)院集中式數(shù)據(jù)中心系統(tǒng)進(jìn)行改進(jìn),將極大提升其綜合性能,將為四川托普學(xué)院信息化建設(shè)帶來新的動(dòng)力。本文利用H3C CAS虛擬化云計(jì)算管理平臺(tái),對(duì)四川托普信息技術(shù)職業(yè)學(xué)院現(xiàn)有數(shù)據(jù)中心系統(tǒng)進(jìn)行升級(jí)改造,詳細(xì)闡述了數(shù)據(jù)中心系統(tǒng)虛擬化改造的一般思路和實(shí)施方法。并對(duì)H3C CAS云計(jì)算平臺(tái)缺乏對(duì)管理節(jié)點(diǎn)(CVM節(jié)點(diǎn))的運(yùn)行監(jiān)控手段這一薄弱環(huán)節(jié)進(jìn)行了分析,有針對(duì)性地設(shè)計(jì)了解決方案:在Linux環(huán)境下設(shè)計(jì)基于UDP協(xié)議的心跳監(jiān)測程序,完成對(duì)CVM節(jié)點(diǎn)的動(dòng)態(tài)監(jiān)測,以提升系統(tǒng)運(yùn)行的穩(wěn)定性。接著為改造后的數(shù)據(jù)中心系統(tǒng)設(shè)計(jì)了嚴(yán)謹(jǐn)?shù)臏y試對(duì)比實(shí)驗(yàn),以測試項(xiàng)目實(shí)施前后關(guān)鍵業(yè)務(wù)應(yīng)對(duì)突發(fā)的海量訪問的能力。最后從多方面對(duì)改造后的項(xiàng)目進(jìn)行了詳細(xì)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.
