摘要： 介绍了虚拟存储的形式及实现层次，并在Windows平台下，利用现有的网络环境，在主机设备驱动层实现基于块存储的虚拟网络存储的一种方法，主机通过运行驱动程序将整个或一部分网络存储空间映射为本地的磁盘，然后像对本地盘一样对该盘进行格式化、创建文件系统、存储文件，从而实现网络存储。整个虚拟空间既可以映射为主机的单一硬盘，构成海量存储器，也可将虚拟空间根据不同主机要求映射为不同容量的虚拟磁盘，构成网络移动磁盘。

Abstract: This paper introduces several virtual storage forms and different levels of their realization, and gives a method to realize virtual network storage based on the block device under Windows by using the existing network environment. The host images part or the whole LAN into a local physical disk by running the driver program. Then user can format,create file system , read or write file in this virtual disk like local disk to realize network storage.The whole virtual space not only can be imaged into one huge disk for one host but also can be imaged into different mobile disks according to the host requirement.
