分析了云计算数据中心的存储需求,探讨了NAS和SAN的工作机制,对其在虚拟机环境下的性能进行比较测试。实验表明,在虚拟机环境下NAS和SAN之间的性能差异小于10%,远小于传统应用环境中的性能差异。综合考虑存储系统的可扩展性、易管理性等多种因素,在虚拟机环境下使用NAS存储是更为合理的方案。
Abstract：This paper analyzes the storage requirements of cloud computing data center, discusses the working mechanism of NAS and SAN, and compares the performance of storage in the virtual machine environment. Experiments show that the performance differences between the NAS and SAN in the virtual machine environment are less than 10%, far less than the performance differences in the traditional application environment. Considering the extensibility and manageability of storage system, the use of NAS storage in a virtual machine environment is a more reasonable scheme.
