Abstract

Aspects include receiving a request from a requesting system to move data from a source memory on a source system to a target memory on a target system. The receiving is at a first hardware engine configured to access the source memory and the target memory. In response to receiving the request, the first hardware engine reads the data from the source memory and writes the data to the target memory. In response to the reading being completed, the first hardware engine transmits a data clearing request to a second hardware engine that is configured to access the source memory. The data clearing request specifies a location of the data in the source memory to be cleared.
