摘要
存储虚拟化技术是基于网络的存储管理技术,它屏蔽大量异构设备的差异性,向用户提供简单的逻辑存储访问接口;它简化了存储管理,优化了系统性能,提高了存储设备的利用率。本文从存储虚拟化的概念入手,详细分析了存储虚拟化的模型结构、分层、采用的协议等方面的内容,介绍了当前虚拟化技术的最新进展,讨论了基于网络的虚拟存储技术的优点和不足。
Storage virtualization techno logies is the network - based storage management techno logies; it screens the differences of heterogeneous storage appliances, supply users with simple logic storage access interface;it simplifies storage management, optimizes the storage performance and improve the availability of storage devices. We first introduced the conception of storage virtualization and analyzed the model of storage virtualization, its hierarchy and popular protocols adapted by storage virtualization. We also discussed the latest tendency of storage virtualization and pointed out their advantages and disadvantages of those technologies.
