Abstract
A first storage system includes a plurality of first storage devices and is coupled to a computer. A second storage system includes a plurality of second storage devices and is coupled to the first storage system. A first controller provides a thin provisioning logical volume (LU) to the computer. A second controller provides an external thin provisioning LU to the first storage system. The first controller provides pool areas associated with the thin provisioning LU, including a first pool area mapped to the external thin provisioning LU, and allocates the first pool area to a first region in the thin provisioning LU to store a write data to the first region in the thin provisioning LU. The second controller allocates at least one of a plurality of pool areas to store the write data to the first region in the thin provisioning LU.
