Abstract
A method of performing an input/output (I/O) processing operation includes: generating at least one address control word (ACW) specifying one or more host memory locations for transfer of data between a host computer system and a control unit, and storing the at least one ACW in the local channel memory; generating an address control structure for each data transfer specified by the I/O operation and forwarding each address control structure from the at least one channel to the network interface; forwarding an I/O command message to the at least one I/O device via a network interface; receiving a data transfer request from the network interface that includes the address control structure; and routing the data to at least one host memory location specified by the corresponding ACW or routing the data from a host memory location specified by the ACW to the network interface.
