Abstract
The influence of new deployment of volumes on the performance is predicted with accuracy in a storage system that includes a main site holding a primary volume and a sub-site holding a secondary volume and a journal volume. The main site has one or multiple nodes. The sub-site has multiple nodes. In creating a new secondary volume and a new journal volume in the sub-site, a management program that operates in any node or a predetermined management apparatus predicts the load of the processor under an operation condition in which redundancy processing is executed in the sub-site regarding the new secondary volume, predicts the load under an operation condition in which redundancy processing is not executed in the sub-site regarding the new journal volume, and selects a node that becomes the deployment destination of the new volumes on the basis of the result of the prediction of the load.
