Abstract: Modern data intensive applications need continuous high-performance storage service. Moreover the needs for capacity and performance are prone to vary with time. Storage system needs meet these requests with least expenses. After analyzing storage network throughput model, a performance optimization method that reconfiguring mapping structure of storage network through data migration is proposed. Furthermore a solution of providing continuous high-performance storage service during performance optimizing is presented. Finally a method of calculating system parameter is presented.
