Abstract
It is an object to prevent a processing speed of the storage system provided with a function for detecting a write completion of data from being reduced. A controller module is provided with at least one processor module, at least one storage resource, and at least one transfer control module connected to the processor module and the storage resource. The transfer control module is provided with a receiver and a transmitter. The receiver receives a write packet from the processor module, includes a specific code in the write packet, and then transmits the write packet. In the case in which the transmitter receives a write packet and the received write packet includes the specific code, the transmitter writes targeted data in the write packet to the storage resource to be written, generates a response packet that is a response indicating a completion of a write, and transmits the generated response packet.
