With the deepening of informatization in higher education, the operation and maintenance of public computer labs face challenges such as low system deployment efficiency, difficult software environment maintenance, and significant data security risks. Cloud desktop technology offers an effective solution to these problems. This paper investigates the RDV5 cloud desktop system, systematically analyzing its VOI (Virtual OS Infrastructure) architecture based on four design principles: centralized storage, distributed computing, disk-network convergence, and data offloading. Key technologies including system architecture, network boot process, master disk and copy-on-write mechanism, multi-level caching with filter drivers, and offline hot-switching are elaborated through diagrams and descriptions. Combined with the practical deployment requirements of university computer labs, the application value of this system in unified management, rapid deployment, automatic restoration, and data security is analyzed.
