On the basis of the research of previous object storage metadata management strategies,this paper puts forward a new kind of metadata management strategy.The method is to divide namespace directory into neutron trees,and compute with hash function using the combination of the root directory name and file name.Metadata Server(MDS) determines its storage path according to the hash value.Experimental result shows that this new kind of metadata management tactics can avoid the massive metadata migration problems and network overhead problems in dealing with metadata rename operation and modify filename.
