Abstract: Researches on technologies about testing aggregate bandwidth of file systems in cloud storage systems. We propose ways to take evaluations on file system aggregate bandwidth and develop parallel file system aggregate bandwidth test software called FSPoly. In this paper, we take full-proof on validity of FSPoly and realize evaluations on memory file system, network file system and parallel file system by using FSPoly.

Key words: loud Storage System, Aggregate Bandwidth, File System, Test Technology, Performance Analysis
