Title: Storage apparatus and data transfer method

Abstract: This storage apparatus includes multiple controllers, a transfer path, and multiple processors. Each of the multiple controllers is connected to the same or a different processor. A first processor connected to a controller that received a transfer command from the host system determines, based on the transfer command, a first controller to become a transfer source of data and a second controller to become a transfer destination of the data, and determines a path belonging to the transfer path between the first controller and second controller. If there are multiple paths, a path in which the number of controllers connected other than to the second controller becomes maximum as a specific path, and the multiple processors transfer data between the first controller and the second controller along with the specific path.
