Abstract
A system comprises a first storage system including a first storage controller, which receives input/output commands from host computers and provides first storage volumes to the host computers; and a second storage system including a second storage controller which receives input/output commands from host computers and provides second storage volumes to the host computers. A first data storing region of one of the first storage volumes is allocated from a first pool by the first storage controller. A second data storing region of another one of the first storage volumes is allocated from a second pool by the first storage controller. A third data storing region of one of the second storage volumes is allocated from the first pool by the second storage controller. A fourth data storing region of another one of the second storage volumes is allocated from the second pool by the second storage controller.
