服务器虚拟化应用的研究与实践

Research and Practice of Server Virtualization Technology

企业信息化建设与应用不断发展,信息管理与应用、运行维护逐渐出现了一些新问题,主要表现在基础设施建设滞后于信息管理与应用,信息系统和配套设备的运维工作量大、运营成本高,部分非关键信息系统可靠性较差、利用效率较低。通过服务器虚拟化技术,采用将硬件资源整合后交付给软件使用的模式,有效地将系统硬件资源和软件应用进行分离,使信息管理人员按需随时可将服务器资源分配给最需要的应用负载,从而减少为单个工作负载峰值而储备的硬件资源。实现整合并减少了系统设备资源,降低了系统设备资源的管理和运营成本;提升了利用效率和可靠性。

With continuous development of information system, enterprises are confronted with new problems in management, application and maintenance of information systems, such as insufficient infrastructure construction which is slower than information system development, high maintenance costs which go with tremendous amount of work, and poor-working non-key information systems which are neither reliable nor efficient. Server virtualization technology, is which can decrease standby hardware resources by using hardware integration system to allocate server capacity to the particular software in work load peaks. By integration hardware, the technology can cut operation cost, and improve system efficiency and effectiveness as well.
