| Abstract(in English) | Data migration is an efficient method to handle skew of access request distribution in the field of distributed storage systems. However, it also can cause a performance degradation temporally because it uses system resources such as local I/O or networks. In this paper, we propose a method to decrease performance degradation of data migration, distributing access requests to replica-data. To use the method, we can use data migration even if access requests concentrate on a node. We also show the efficiency of our method by using the result of experiments. |
