Abstract
A storage device system includes an information processing device, a first storage device equipped with a first storage volume, and a second storage device equipped with a second storage volume. The information processing device and the first storage device are communicatively connected to one another. Also, the first storage device and the second storage device are communicatively connected to one another. The information processing device is equipped with a first write request section that requests to write data in the first storage device according to a first communications protocol, and a second write request section that requests to write data in the second storage device according to a second communications protocol. The information processing device creates first data including a first instruction to be executed in the second storage device. The information processing device transmits to the first write request section a request to write the first data in the first storage volume according to the first communications protocol. When the first data written in the first storage volume is an instruction to the second storage device, the first storage device transmits to the second write request section a request to write the first data in the second storage volume according to the second communications protocol. The second storage device executes the first instruction set in the first data written in the second storage volume.
