Comparison of replica assisting and speed adjustment for service-aware horizontal data migration on autonomous disks
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 efficiency of this method with experimental results on simulation program, comparing to speed adjusting method which is widely used for service-aware data migration.
