A switch-based inter-device notational data movement system includes a switch device that is coupled to a first processing system included in a first chassis and configured to provide a first thread, a second processing system included in a second chassis and configured to provide a second thread, and a memory system. The switch device identifies, in a communication transmitted by the first thread, a request to transfer data, which is stored in a first portion of the memory system that is associated with the first thread in a memory fabric management database, to the second thread. The switch device then modifies notational reference information in the memory fabric management database to disassociate the first portion of the memory system and the first thread and associate the first portion of the memory system with the second thread, which allows the second thread to reference the data using request/respond operation.
