| Abstract: | The dawning super-server is a typical cluster system, for which a COSMOS file system has been developed. Mainly presented in this paper are the design, implementation, and evaluation of the prototype COSMOS file system. Here highlihted are some key technologies such as dual.granularity cooperative cache, distributed meta-data management, network disk stripping and so on. The performance of the prototype file system is also evaluated by the use of the standard I/O benchmarks. The initial performance measurements show that our approach is a promising one in providing scalable single-image file system. |
