Application Of Virtualization Technology In Enterprise Information Management

In recent years,with the rapid development of network application and information technology,enterprises have become more and more dependent on network and information technology.Data center as the core of the enterprise information construction area,running many hardware devices,such as firewalls,switches,servers,storage,and the corresponding application system,such as ERP,OA,CRM,SRM,PLM.Hardware equipment as the physical carrier of the information system under network stable operation and provide the basis of the application service,operating system,provides a software application system running environment,hardware and software to cooperate to ensure the stability of the network environment,the application system stable operation and data security,etc.LAN management problems of the face in the enterprise data center(such as networking equipment management chaos,frequent network broadcast storm,a single point of failure and low efficiency of data forwarding network,network capacity is insufficient,etc.),low server resource utilization problem,data security and sharing,etc.,using virtualization technology to provide solutions.Paper by consulting a large number of documents based on data center virtualization technology,virtualization in the informatization construction of hardware and software products,such as technical characteristics are studied,and on the basis of the virtualization system architecture design and equipment selection,implement virtualization platform to build,and deployment of application systems in the virtual environment.(1)Application mode based on Mac address global division of Vlan and combining the IP and Mac binding technology solve the networking equipment management chaos,frequent and not flexible networking site LAN broadcast storm problem,application switches IRF virtualization technology to solve local area network(LAN)low bearing capacity,low efficiency of the network data forwarding,and the problem such as network outages caused by a single point of failure.(2)Using the concept of resource pool,the problem of low utilization of server hardware resources and the application system's on-line,backup and recovery cycle is solved through Xen server virtualization technology.(3)Combined with network and server virtualization technology,the application of Vlan access control and data centralized storage,classification and sharing,etc.to solve the problems of data security and sharing.Practice shows that the construction of network and information technology in the enterprise,through virtualization technology can provide a good network environment,security of data transmission,and effective resource sharing,especially on some of the key business or classified system,the operation of virtualization technology to guarantee system stability and security.
