Paper Abstract

Metadata service system is a latent access bottleneck in a large distributed storage system. The traditional methods of metadata distribution and management does not take more dynamic load balancing into account especially in heterogeneous MDS(MetaData Server, MDS) cluster, therefore it is very easy to become hotspots . This paper introduces a linear chain load balancing policy based on hybrid method which has both the advantages of the directory subtree partitioning and the pure hashing in MDS cluster. Comparing with traditional methods, it can dynamically distributes and manages metadata according to the workload of every MDS in heterogeneous MDS cluster. Finally it is proved to have good load balancing by analyzing the arithmetic theoretically and simulation test.
