Remote storage disk control device and method for controlling the same

A storage device system comprising:

• 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;
• wherein the information processing device and the first storage device are communicatively connected to one another,
• 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,
• the first storage device is equipped with 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 is equipped with an instruction setting section that creates first data including a first instruction to be executed in the second storage device, and an instruction transmission section that 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,
• the first storage device is equipped with a data transfer section that, when the first data written in the first storage volume is an instruction to the second 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, and
• the second storage device is equipped with an instruction execution section that executes the first instruction set in the first data written in the second storage volume.

A storage device comprising:

• at least first and second storage devices communicatively connected to each other;
• a first storage volume in the first storage device;
• a second write request section in the first storage device that requests the second storage device to write data in the second storage device according to a second communications protocol;
• and
• a data transfer section in the first storage device that, when first data written in the first storage volume is an instruction to the second storage device, transmits to the second write request section a request to write the first data in a second storage volume of the second storage device according to the second communications protocol.

A method for controlling a storage device system, the storage device system including

• 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,
• wherein 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
• the first storage device is equipped with a second write request section that requests to write data in the second storage device according to a second communications protocol,
• the method comprising:
• a step of creating first data including a first instruction to be executed by the second storage device;
• a step of transmitting to the first write request section a request to write the first data in the first storage volume according to the first communications protocol;
• a step of, when the first data written in the first storage volume is an instruction to the second storage device, transmitting to the second write request section a request to write the first data in the second storage volume according to the second communications protocol;
• and
• a step of executing the first instruction set in the first data written in the second storage volume.
