We have previously proposed Autonomous Disks System as a dependable and high-performance networked parallel storage system. The system has function of load balancing by online horizontal data migration. However, the migration causes a reduction of system availability by insensitively utilizing of system resources for massive data transfers. Thus we have also proposed Replica-assisted Migration, which solve the problem by using replica data for data redundancy. In this paper we show the
