中文摘要：

通过分析VMwarevSpher产品及相关虚拟化技术，提出一种私有云数据中心基础架构设计方案，从ESX主机、Vcenterserver动态资源分配管理、VMwareVmotion虚拟机迁移技术和VMwareDataRecovery快照技术四个方面测试并证明了方案的可行性．最后用TCO计算器计算出构建私有云的成本，数据显示在部署大量高性能服务器进行虚拟化的前提下具有比传统数据中心更低的成本优势．

英文摘要：

By analyzing the VMware vSpher products and related virtualization technologies, proposed a private cloud data center infrastructure design. From the ESX host.dynamic resource allocation management on Veenter server. virtual machine migration technology by VMware Vmotion and VMware Data Recovery snapshot technology four parts, the feasibility of which are tested and proved. Finally, we use TCO calculator to calculate the cost of private cloud, the data show that which is less than traditional data center if deploy a large number of high-performance servers by virtualization.
