This paper analyzes the problems of load balance caused by data access in parallel file systems and gives an accurate way to estimate the load of Data Servers. On the base of this evaluation, the paper proposes an adaptive loading data migration (ALDM) strategy to balance the load of data servers. Experiment results show ALDM has little impact on system performance during data migration, and the performance improves about 10% after data migration completed. Furthermore, ALDM also has good adaptability to various loads in different storage systems.
