Abstract:
1. A computer comprising: a processor; a performance calculation unit; and a second storage device determination unit, wherein the performance calculation unit causes the processor to execute steps of: wherein the second storage device determination unit causes the processor to execute a step of identifying a second storage device having a storage device access performance index that is equal to or greater than a second storage device access performance index, wherein the second storage device access performance index is determined based on the calculated first storage device access performance index, wherein the second storage device is identified by referencing the storage medium performance information and second configuration information relating to a configuration of a second storage system having the second storage device related to the first storage device, wherein the first storage device is a copy source storage device, wherein the second storage device is a copy destination storage device, wherein the first storage device access performance index is a copy source reading performance index, which is an index of a reading performance of the copy source storage device, wherein the second storage device access performance index is a copy destination writing performance index, which is an index of a writing performance of the copy destination storage device, and wherein the copy destination writing performance index determined on the basis of the calculated copy source reading performance index exceeds the copy source reading performance index.
