Application Study On Virtualization Technology In The Process Of Campus Digital Construction

The completion and development of digital campus business systems have brought big changes in teaching,scientific research and management,etc.to colleges and universities.But if lacks of unified planning in the process of digital campus construction,a number of servers and computers in digital data centers and laboratories of colleges and universities will surge.The sharp growth in the number of servers and computers will lead to low rates of resource availability and utilization,inflexible resource allocation,big difficulty in management.How to solve these problems existing in the process of digital campus construction has become a hard nut to crack at present.This thesis first describes the construction of virtual system is the solution to the hard nut.Second this thesis also describes the key technologies including DRS,HA,etc.in the process of virtualization system construction.Finally,a demand analysis for virtualization in the digital campus construction is presented,and based on VMware VCloud Suite,the virtualization deployment is implemented,and a set of construction plan for colleges and universities for virtualized campus network is developed and applied.The test shows that the plan has obtained more satisfactory results.The main works is follow:On the basis of demand analysis for digital campus,this thesis puts forward a physical/virtual hybrid system architecture with those technologies:the server virtualization,network virtualization and storage virtualization and achieves the deployment.The hybrid system architecture virtualization system is able to obtain high performance and protect the existing equipment investment.In this thesis,the virtual system integrates data center under construction into one.The systems of the original 30 multi server reasonably virtual integrate and migrate to the 4 high performance server cluster,which upgrade the server resource usage.Using a distributed resource scheduling(DRS)technology,the system realizes dynamic allocation of virtual platform resources and unified management;adopting High availability(HA)technology,combining with the Cisco server cluster load balancing,finally we improves the usability of service virtualization system and cluster automatic,dynamic allocation of resources.Through desktop virtual deployment,we realize desktop virtualization on most laboratory,office computer.After deploying desktop virtualization system,we can allocate desktop environment in the form of dynamic,improve business agility and user security,solve difficult management maintenance problems due to the number of terminal.This thesis constructs the virtual system aiming at solving the existing problems in the traditional digital campus.The system has been flexible and extensible to meet the long-term development needs for information construction and also has certain reference value and guiding significance to the school resource integration and digitization construction.
