A storage device system includes an information processing device and at
least first and second storage devices. The first and second storage
devices are equipped with first and second storage volumes, respectively.
The information processing device generates first data including a first
instruction that is to be executed by the second storage device, and
sends a write request to a first write request section to write the first
data according to a first communications protocol in the first storage
volume. When the first data written in the first storage volume is the
command to be executed by the second storage device, the first storage
device sends to a second write request section a write request to write
the first data according to a second communications protocol in the
second storage volume. The second storage device executes the first
command set in the first data that is written in the second storage
volume.
