Abstract
On embodiment includes a computer program product for performing a method including: obtaining information relating to an I/O operation at a channel subsystem in a host computer system; generating addressing information and forwarding the addressing information from at least one channel to a network interface between the channel subsystem and at least one I/O device, the addressing information specifying a location in a local channel memory; forwarding an I/O command message to the at least one I/O device via the network interface; responsive to the I/O command message, receiving a data transfer request from the network interface that includes the addressing information; responsive to receiving the data transfer request, accessing one of a plurality of address control words (ACWs), each ACW specifying an address of a location in a host computer memory; and routing the data transfer request to the host memory location specified in the ACW.
