A network-attached CD Image file server, working on the Linux operating system, is implemented. By taking advantage of virtual file system (VFS) infrastructure and loopback device, the data of CD are mirrored in harddisks and can be shared by clients synchronously through network. The primary benefits of such a server are cost effectiveness, high capacity and excellent compatibility with Chinese characters. The performance of the server is evaluated by testing its throughput during I/O request. The experimental results show that, compared with conventional methods such as sharing the CD-ROM hard devices via network as, the rate of reading data from the CD Image is much higher. This is especially true when the server is dealing with multi-client access.
