Abstract: A host I/F unit has a management table for managing an MPPK which is in-charge of the control of input/output processing for a storage area of an LDEV, and if a host computer transmits an input/output request for the LDEV, the host I/F unit transfers the input/output request to the MPPK which is in-charge of the input/output processing for the LDEV based on the management table, an MP of the MPPK performs the input/output processing based on the input/output request, and the MP of the MPPK also judges whether the MPPK that is in-charge of the input/output processing for the LDEV is to be changed, and sets the management table so that an MPPK which is different from the MPPK that is in-charge is to be in-charge of the input/output processing for the LDEV.

Abstract: A first storage system copies data of a virtual area of a first virtual volume to a virtual area of a second virtual volume of a second storage system, monitors accesses with respect to multiple virtual areas of the first virtual volume, updates access information related to the accesses of the multiple virtual areas, and, based on the access information, reallocates data inside an actual area of a first pool allocated to the virtual area of the first virtual volume. The first storage system sends the access information to the second storage system. The second storage system receives the access information, and, based on the access information, reallocates data inside the actual area allocated to a virtual area of the second virtual volume.
