Abstract
Metadata distribution is important in mass storage system. Sub-tree partition and hash are two traditional metadata distribution algorithms used in file system. But they both have a defect in system scalability. This paper presents a new metadata management method, Directory Path Code Hash (“DPCH”). This method is to store directory and file metadata separately, and effectively solving the unbalanced metadata distribution and access hot point problems in Sub-tree partition and the excessive reading times and large metadata migration amount after directory property modification in hash algorithm. The experiment indicates that this method proposed significantly outweighs other algorithms in terms of throughput rate, metadata distribution, reading times, etc.
