The feasibility research of cloud storage based on Global File System

Cloud storage is the extension and development based on the cloud computing, which should not only provide the conventional file access just like POSIX, but also must be able to support the massive data management and the public service support functions. GFS (Global File System) is a solution for massively parallel computing and cloud storage, and its high availability and good scalability can assure the data that it can be more secure and reliable stored and more efficiently scheduled. In this paper we test the GFS environment, and study the file system recovery when node damage happening, and compare the GFS with ext3, NFS system in read and write performance. The experiment result and the practical system performance shows, GFS can provide effective support for the cloud storage, and provide good storage and calculation for cloud computing.
