Abstract: 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.

Abstract: A switch-based inter-device notational data movement system includes a first processing system in a first chassis that provides a first thread, a second processing system in a second chassis that provides a second thread, each of which are coupled to a memory system by a switch device. A controller device coupled to the switch device receives a data transfer communication from the first thread requesting to transfer data to the second thread. That data stored in a first portion of the memory system associated with the first thread in a memory fabric management database included in the switch device. The controller 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, allowing the second thread to reference the data using request/respond operation.

The splitter device then splits the first data payload into the first data sub-payload and the second data sub-payload, and forwards both the first data sub-payload to the first endpoint subsystem and the second data sub-payload to the second endpoint subsystem.

Abstract: A processing subsystem/endpoint subsystem connection configuration system includes a plurality of processing subsystems and a multi-endpoint adapter device that provides a plurality of endpoint subsystems. A bus exchange switch device couples the plurality of processing subsystems to the plurality of endpoint subsystems, and a connection configuration engine is coupled to the multi-endpoint adapter device and the bus exchange switch device. The connection configuration engine receives a connection resource request that requests connection resources for a first processing subsystem that is included in the plurality of processing subsystems. Based on the connection resource request, the connection configuration engine causes at least one of the plurality of endpoint subsystems to perform a first connection resource change operation. The connection configuration engine then configures the bus exchange switch device to provide the connection resources for the first processing subsystem.

Abstract: A multi-port storage device multi-socket memory access system includes a plurality of processing subsystems interconnected by at least one processing subsystem interconnect, a respective local memory subsystem for each of the processing subsystems, and a storage system that provides a respective connection to each of the processing subsystems.

The storage system then accesses the first memory subsystem through the first connection, via the first processing system, and without utilizing the at least one processing subsystem interconnect, in order to execute the memory access command.
