An object of the invention is to provide a transfer system, initiator device, and data transfer method that can improve data transfer-related performance by fully utilizing a high-speed interface even when transferring data between devices that execute data processing at different speed. The invention provides a transfer system including: an initiator device, plural target devices, and a switch for switching data transfer targets between the initiator device and target devices, wherein either the initiator device or the target devices are connected to the switch via a high-speed interface and the other is connected to the switch via a low-speed interface, and the initiator device has a control unit for determining the data transfer length of data transferred to a first target device in the target devices according to the status of data transfer to the other target device(s) when transferring data between the initiator device and the first target device.
A transfer system comprising:
An initiator device comprising a control unit connected, via a high-speed or low-speed interface, to a switch for switching targets that are plural target devices data is transferred to, the control unit determining, according to the status of data transfer to the target device(s) other than a first target device in the target devices, the data transfer length for data transfer to the first target device when data is transferred to the first target device.
A method for transferring data between an initiator device and plural target devices, either the initiator device or the target devices being connected, via a high-speed interface, to a switch for switching targets of data transfer between the initiator and the target devices, and the other being connected to the switch via a low-speed interface,
