1. A computer system comprising:
an information storage system including one or more main storage apparatuses and one or more remote storage apparatuses; and a management system for managing the information storage system, the information storage system including a plurality of asynchronous remote copy pairs, the plurality of asynchronous remote copy pairs each consisting of a primary volume provided by the one or more main storage apparatuses and a secondary volume provided by the one or more remote storage apparatuses, the plurality of asynchronous remote copy pairs being divided into a plurality of pair groups each including one or more asynchronous remote copy pairs, the management system including:
pair management information for managing relations between the plurality of pair groups and one or more asynchronous remote copy pairs included in the plurality of pair groups; andresource management information for managing resources allocated to the plurality of pair groups to be used to transfer copy data in asynchronous remote copy, wherein the management system monitors data transfer latencies in asynchronous remote copy in the plurality of pair groups, wherein, in a case where data transfer latencies in a first pair group of the plurality of 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, and wherein 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. |
