A virtual machine deployment system includes a plurality of processing subsystems, and at least one multi-endpoint adapter device including a plurality of endpoint subsystems. A plurality of communication couplings couple each of the plurality of endpoint subsystems to at least one of the plurality of processing subsystems in order to provide a respective subset of available communication resources to each of the plurality of processing subsystems. A virtual machine deployment engine receives an instruction to deploy a virtual machine, and determines at least one communication resource requirement for the virtual machine. The virtual machine deployment engine then identifies a first processing subsystem that is included in the plurality of processing subsystems and that is provided a first subset of the available communication resources that satisfies the at least one communication resource requirement for the virtual machine, and deploys the virtual machine on the first processing subsystem.

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.

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.

An application image cloning system includes a processing system that is coupled to a memory fabric memory system and a local memory system. The processing system provides a first application and a second application using an application image stored in the memory fabric memory system and provides a mapping engine. The mapping engine receives, from the first application, a store request to store a modified memory page that is a modified version of a memory page included in the application image, such that the memory page is stored in a memory fabric memory location in the memory fabric memory system. The mapping engine stores the modified memory page in a local memory location in the local memory system, disassociates the first application from the memory fabric memory location that stores the memory page, and associate the first application with the local memory location that stores the modified memory page.

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.

A processor/endpoint communication coupling configuration system includes a plurality of processing subsystems coupled to a multi-endpoint adapter device by a plurality of communication couplings included on at least one hardware subsystem. A communication coupling configuration engine identifies each at least one hardware subsystem, determines at least one communication coupling configuration capability of the plurality of communication couplings, and determines at least one first multi-endpoint adapter device capability of the multi-endpoint adapter device. The communication coupling configuration engine then configures the plurality of communication couplings based on the at least one hardware subsystem, the at least one communication configuration capability, and the at least one first multi-endpoint adapter device capability in order to provide at least one communication resource between at least one of the plurality of processing subsystems and at least one endpoint on the first multi-endpoint adapter device.

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.

A memory tiering system includes a data mover device coupling 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.

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.

In one or more embodiments, one or more systems, processes, and/or methods may utilize a trace unit that stores trace data via a trace buffer in a memory medium and may utilize a network interface that provides the trace data from the trace buffer to a network. In one example, the network interface may provide the trace data from the trace buffer to the network in response to a trigger. In one instance, the trigger may include a modification of a pointer to an address of the trace buffer. In another instance, the trigger may include an expiration of a timer. In another example, the trace unit may filter the trace data. In one or more embodiments, storing the traced data and providing the trace data to the network may be performed without involving a main processor of an information handling system that includes the trace unit.
