Abstract
For parallel, massively parallel and data server networks a zone relocation facility and dynamic I/O data address relocation facility which allows the relocation of memory space for partitions for on or more clients or guests while the client guest and one or more of the server/host or another client guest are actively executing I/O instructions. An I/O data address relocation facility includes an operation request block in the local storage of a client/guest with a second copy of the operation request block in a server/host located in the main store, and a comparator in the system channel subsystem. An application locates CCWs and IDAWS anywhere and the server/host will relocate data to its partition. The partition size can be expanded to allow dynamic response to a need for memory by changing the partition and moving data to the expanded partition while other activities are being processed.
