Abstract
A storage system according to the present invention includes: a plurality of storage devices, wherein each of a plurality of the storage devices including: a control unit; and a storage unit that stores data, wherein the control unit of the storage device that receives a request specifies the storage device that includes the storage unit in that target data targeted by the request is stored among a plurality of the storage devices, and the control unit of the storage device that is specified transmits, as a response to the request, the target data and header information in that a destination identifier indicating a destination of the request is set to a source identifier of the response, and a source identifier indicating a source of the request is set to a destination identifier of the response.
Claims4
A storage system comprising:
- a plurality of storage devices, wherein
- each of a plurality of the storage devices including:
- a control unit;
- and
- a storage unit that stores data, wherein
- the control unit of the storage device that receives a request specifies the storage device that includes the storage unit in which target data targeted by the request is stored among the storage devices, and
- the control unit of the storage device that is specified transmits, as a response to the request, the target data and header information in which a destination identifier indicating a destination of the request is set to a source identifier of the response, and a source identifier indicating a source of the request is set to a destination identifier of the response, wherein,
- when the control unit of a first storage device among the storage devices receives the request transmitted from a server device, and the storage unit of a second storage device that is different from the first storage device among the storage devices stores the target data,
- the control unit of the first storage device identifies the second storage device, and
- the control unit of the second storage device transmits, as the response, the target data and the header information in which information indicating the first storage device is set to the source identifier of the response, information indicating the server device is set to the destination identifier of the response, and information indicating the server device is set to an originator identifier that identifies an originator starting the request.
A communicating method of a storage system that includes a plurality of storage devices, the communicating method comprising:
- by a storage device that received a request, identifying the storage device having a storage unit in which target data of the request is stored among the storage devices;
- and
- by the storage device that is identified, transmitting, as a response to the request, the target data and header information in which a destination identifier indicating a destination of the request is set to a source identifier of the response, and a source identifier indicating a source of the request is set to a destination identifier of the response
- further comprising:
- when, by a first storage device among the storage devices, receiving the request transmitted from a server device, and by the storage of a second storage device that is different from the first storage device among the storage devices, storing the target data,
- by the first storage device, identifying the second storage device;
- and
- by the second storage device, transmitting, as the response, the target data and the header information in which information indicating the first storage device is set to the source identifier of the response, information indicating the server device is set to the destination identifier of the response, and information indicating the server device is set to an originator identifier that identifies an originator starting the request.
