The two-layered distributed clustered server architecture consisting of a control server and a group of storage servers has been widely used to support multimedia file systems. With this kind of the server architecture, it is easy to sustain disk load balancing and scalable disk bandwidth. However, it brings about the communication overhead between the control server and storage servers. Therefore, to reduce such overhead, media data should be transmitted from the storage servers to the users directly without the intervention of the control server. In addition, the file system must support the effective data placement and disk scheduling policies and should be designed to sustain portability and flexibility in any hardware or software environment to cope with rapidly developed hardware and software technologies.So, to fulfill such requirements described in the above statements, we designed and implemented a parallel file system named PMFS(Parallel Multimedia File System) and analyzed its performance by comparing it with PVFS(Parallel Virtual File System). As a result of our experimental simulation, we came to conclusion that the PMFS shows better performance than the PVFS does in real time data processing.
