Abstract
An input/output processing method includes generating and storing at least one address control word (ACW) including a data check word generation field and/or a data check word save field in local channel memory of a channel subsystem, and generating and forwarding to a network interface an address control structure specifying a location in the local channel memory of a corresponding ACW. The method also includes, responsive to a data transfer request, storing the at least one data check word in the data check word save field and routing the data to a host memory location specified by the corresponding ACW responsive to performing a check of the data and determining that the data has not been corrupted, or retrieving the data based on the corresponding ACW, generating and appending at least one data check word and routing the data and the at least one data check word to the interface.
