摘　　要：为了满足透明计算环境下用户可以在多种计算设备上使用个性化操作系统和应用的需求,需要通过存储设备驱动完成异构平台上的多操作系统远程加载和运行。目前的驱动模型不能满足透明计算的功能和性能要求。该文提出并实现了一种支持透明计算的虚拟存储设备驱动模型(TVSDM)。该驱动模型独立于操作系统和硬件平台,基于客户端/服务器架构,采用基于块级的虚拟化技术,实现了驱动模型的基本功能,包括总线扫描、虚拟块设备创建和I/O请求处理等。实验结果表明:基于该模型的开发出的原型系统能够完成虚拟存储设备的远程驱动和运行,并具有良好的性能。To meet the demands of users who use personalized operating systems and applications in transparent computing environments, the storage device driver needs to support remote loading and running of multiple operating systems and applications in heterogeneous platforms. Existing device driver models are not suitable for transparent computing environments in terms of functionality and performance. This paper presents a virtual storage device driver model for transparent computing, TVSDM, that is independent of the operating system and device platform. The TVSDM client/server architecture provides general block level-based driver model functions, such as bus scan, block device creation, and I/O processes. Tests demonstrate that a prototype system based on TVSDM can support remote driving and running of a virtual storage device with good performance.
