Abstract
The management system includes pair management information for managing pair groups and resource management information for managing resources allocated to the pair groups. The management system monitors data transfer latencies in asynchronous remote copy in the pair groups. In a case where data transfer latencies in a first pair group of the pair groups reach a threshold, the management system selects a first asynchronous remote copy pair from the first pair group with reference to the pair management information. The management system selects a second pair group allocated resources different from resources allocated to the first pair group as a candidate migration destination of the first asynchronous remote copy pair with reference to the resource management information.
