Abstract
The mainly traditional File Systems are constructed on single device where the metadata and data access interfere with each other which will lead to performance degradations. In this paper we propose a volume based mechanism in BWFS to separate metadata from data into different devices by isolations both in store location and IO path. Test result has verified the effectiveness of metadata isolation. By separating metadata into high-performance storage, the application IO bandwidth is promoted by 2.6~2.8 times, meanwhile, the OPS is improved by 2~5 times.
