Abstract: A memory tiering system includes a data mover device coupilng a memory fabric to a processing system. At each of a plurality of different times, the data mover device receives a data access request for data from a computer context provided by the processing system, retrieves the data based on a compute-context-memory-fabric mapping that maps the compute context to the first memory subsystem, and provides the data to the processing system for use with the computer context. If the data mover device determines that the data has been retrieved and provisioning for use with the compute context above a memory tiering frequency, it moves the data from the first memory subsystem to a second memory subsystem in the memory fabric that includes higher performance memory characteristics, and causes the compute-context-memory-fabric mapping to be modified to provide a modified compute-context-memory-fabric mapping that maps the compute context to the second memory subsystem.

Abstract: A memory-fabric-based processor context switching system includes server devices coupled to a memory fabric. A first processing system in a first server device receives a request to move a process it is executing and, in response, copies first processing system context values to its first local memory system in the first server device, and generates a first data mover instruction that causes a first data mover device in the first server device to transmit the first processing system context values from the first local memory system to the memory fabric. A second processing system in a second server device generates a second data mover instruction that causes a second data mover device in the second server device to retrieve the first processing system context values from the memory fabric and provide the first processing system context values in a second local memory system included in the second server device.

Abstract: A virtual machine migration system that includes an initiator host that provides a virtual machine and receives an instruction to migrate the virtual machine to the target host. The initiator host moves, while the virtual machine is operating on the initiator host, virtual machine data for the virtual machine from a local memory area in a local memory system to a memory fabric memory area in a memory fabric memory system. A first portion of the virtual machine data in the local memory area and a second portion of the virtual machine data in the memory fabric memory area are accessible to the virtual machine and the initiator host during the movement of the virtual machine data. The initiator host stops, in response to all the virtual machine data being moved to the memory fabric memory area, operation of the virtual machine on the initiator host.

Abstract: An application checkpoint and recovery system includes an application provided using application information from a first location in a memory fabric. A data mover device receives an application checkpoint instruction and performs application checkpoint operations including capturing a first version of the application information from the first location in the memory fabric, and providing the first version of the application information in a second location in the memory fabric. The data mover device may receive an application recovery instruction subsequent to the application modifying the first version of the application information to provide a second version of the application information in the first location of the memory fabric, and may transfer the first version of the application information from the second location in the memory fabric to the first location in the memory fabric so that it is available for use in providing the application.

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: An intra-device notational data movement system has a chassis including processing system(s) that are configured to provide a first thread and a second thread. A data mover subsystem in the chassis is coupled to the processing system(s). In a communication transmitted by the first thread, the data mover subsystem identifies a request to transfer data to the second thread that is stored in a first portion of a memory system that is associated with the first thread in a memory fabric management database. The data mover subsystem 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 operations.
