摘要: 基于对虚拟存储技术及其在容灾系统中应用现状的分析,设计一个适用于容灾系统的虚拟文件系统。该系统基于Windows平台,通过在Windows存储栈的层次式结构中添加过滤驱动层来实现上层文件系统与下层卷管理器的隔离。在过滤驱动层中,结合虚拟内存的映射原理和容灾系统的应用需求,实现适用于容灾系统的虚拟存储映射机制。

关键词: 虚拟存储, 容灾, 文件系统, 过滤驱动

Abstract: Based on the analysis of virtual storage technology and its application in disaster tolerant system, this paper designs a virtual file system which is adapted to disaster tolerant system. This system bases on Windows platform, and adds a filter driver layer in Windows storage stack to implement the isolation between file system and volume manager. It implements virtual storage mapping mechanism which is adapted to disaster tolerant system in filter driver layer.

Key words: virtual storage, disaster tolerance, file system, filter driver
