中文摘要：

存储资源共享是网络存储的最基本的任务，为了给用户提供有效的存储资源共享，网络存储的统一化和虚拟化采取了不同的方法：统一化的侧重点在于存储技术、存储资源的整合和存储管理的研究，虚拟化侧重于如何为用户提供更方便的应用环境。统一虚拟存储体系结构则结合了两者的优点，代表着网络存储的将采。本文对网络存储的统一化和虚拟化的现状和存在问题进行了探讨，分析了阻碍统一虚拟存储体系结构实现的不利因素，针对这些存在的问题，本文给出了一个基于自主式存储中介的网络存储系统，该系统结合了网络存储的统一化和存储虚拟化技术，可以看作统一的虚拟存储网络的一个实现。

英文摘要：

The share of storage resources is the basic duty to the network storage. To effectively supply the share of storage resources for the clients, the technologies of network storage integration and that of network storage virtualization are used. The integration of networking storage laid heavy stress on the storage technologies, integrating methods and storage management, while the storage virtualization laid heavy stress on the improvement of the application environment for the clients. Having the advantages of the integration and the virtualization, the universal virtual storage ar chitecture will be the future of networking storage. The technologies of both the integration and the virtualization are introduced in this paper. To realize the universal virtual storage architecture,we still have a lot of job to do. A network storage system based on ASAS（Autonomic Storage Agency System）is introduced, which combines the technologies of the integration and the virtualization,and it can be seen as a kind of methods to realize the universal virtual storage architecture.
