Integration of the cloud desktop and cloud storage platform is urgent for enterprises. However, current proposals for cloud disk arenot satisfactory in terms of the decoupling of virtual computing and business data storage in the cloud desktop environment. Inthis paper, we present a new virtual disk mapping method for cloud desktop storage. In Windows, compared with virtual hard diskmethod of popular cloud disks, the proposed implementation of client based on the virtual disk driver and the file system filterdriver is available for widespread desktop environments, especially for the cloud desktop with limited storage resources. Further-more, our method supports customizable local cache storage, resulting in user-friendly experience for thin-clients of the clouddesktop. The evaluation results show that our virtual disk mapping method performs well in the read-write throughput of differentscale files.
