%X As the subsystem of BWFS for distributed file system metadata service,BWMMS uses a simple"central de- cision,distributed process"mechanism and dynamic decision policy to manage distribution of file metadata workload a- mong multiple metadata servers.To decrease requests needed to the backend distribution decision maker and to increase metadata request efficiency,a metadata distribution cache is introduced on each metadata servers.In this paper,we de- scribe the organization and management of metadata distribution cache and its influence on the backend server and file system metadata efficiency in detail.
