[Abstract]:The Huangpu District education data center was established in 2001. It has been carrying the backbone connection of the district education school, the construction and maintenance of the main application service platform in the district. Because of the lack of overall planning, the original infrastructure of the Huangpu District education data center has been increased with the increasing number of business scale and the number of users in recent years. In the daily maintenance and management, the resource utilization rate is not high and the business continuity is not high. The problem of data center managers has been plagued by the data center managers for a long time.
In order to solve the above problems, this paper introduces the server virtualization technology to use virtualization technology to improve the flexibility of the infrastructure, realize the integration of the business platform and share the physical resources, simplify the construction requirements of the supporting infrastructure, reduce the cost of reconstruction and operation and maintenance, and improve the availability of the business system and the data security. Full nature
This paper first analyzes the current situation and problems of Huangpu District education data center, and summarizes the urgent problems that need to be solved. From the introduction of the concept of virtualization technology and the mainstream trend of the data center, the necessity of the application of server virtualization technology in the data center is discussed. This paper analyzes the implementation methods and methods of server virtualization technology, and further discusses the feasibility of server virtualization technology application. Combining the best practice of server virtualization, a set of solutions for dynamic resource pool based on VMware vSphere is designed and implemented.
The realization of dynamic resource pool is accomplished by 4 steps: planning, design, implementation and evaluation.
Referring to the original design requirements of each business system and the analysis results of historical monitoring data, the construction target of virtual resource pool is set in the planning section.
In the design link, through the fine carding of the history monitoring data and classification of application services, the requirements of performance and capacity are refined. According to the requirements of the planning, the realization methods of various functional components and the realization methods of high availability are designed; independent management components are designed to realize the goal of system management planning; according to business planning, The extensibility of the availability dynamic resource pool of the availability of ESXi host cluster and the recovery of the system back up 4 main functions, respectively, to design a reasonable test evaluation scheme.
The implementation process is mainly based on the vSphere platform to build the basic framework of virtualization and deploy the basic functional modules and management components.
In the evaluation process, the availability of VM is tested and evaluated by loading the analog business load; the availability of the ESXi host cluster is verified by simulating the host failure; the scalability of the dynamic resource pool is verified by the two experiments with the parallel machine expansion and the template rapid deployment; finally, the simulation uses the snapshot function to restore it. The scene of the barrier business system to verify the security of the system
This paper uses the virtual solution provided by VMware to build a dynamic resource pool to integrate the existing server groups through the integration of virtualization, not only improves the flexibility of the infrastructure, improves the use efficiency of the server's physical resources, reduces the cost of upgrading and maintenance of the infrastructure, simplifies the management mode of the server, and improves the management mode. The results of the service level project implementation of the data center show that the dynamic resource pool based on the virtualization technology not only effectively solves the urgent problems that need to be solved in the development of the Huangpu District education data center, but also enhances the flexibility and availability of the infrastructure, so that the Huangpu District education data center can better meet the future.
