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.
A system, comprising:
A computer adapted to be coupled to a plurality of storage systems forming a storage pool, the storage pool including a first storage system of the plurality of storage systems having a first storage controller, which receives input/output (I/O) commands from host computers and provides first storage volumes to the host computers, and a second storage system of the plurality of storage systems including a second storage controller, which receives I/O commands from host computers and provisions second storage volumes to the host computers, the computer comprising:
A non-transitory computer-readable medium encoded with instructions that, when executed on a processor, instruct the processor to perform a method of controlling a plurality of storage systems forming a storage pool, where the storage pool includes a first storage system having a first storage controller, which receives input/output (I/O) 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 I/O commands from host computers and provisions second storage volumes to the host computers, the method comprising:
