虚拟网络存储空间划分与抽象技术研究

Research on Space Partition and Abstract Technology for Storage Virtualization Networking

虚拟网络存储正在成为存储领域研究的热点,然而现有的虚拟化技术大多缺乏具体有效的空间划分与抽象技术。本文在分析网络存储特点的基础上,提出了网络存储的总体抽象拓扑结构模型,给出了一种虚拟网络存储空间的划分与映射方式,并研究了客户端和服务器端的虚拟 I/O 重定向技术,最后探讨了虚拟存储服务器的性能模型。

Virtual network storage is becoming the hotspot in the storage research area. However, the traditional storage virtualization technologies usually lack effective space partition and abstract realization. Based on the analysis of the characters of network storage, this paper introduced a general abstract topology model for network storage and presented a space partition and mapping method for storage virtualization. We also researched the I/O redirection of clients and sever, and then discussed the performance models of virtual storage sever.
