Abstract: An SCP boot system includes a chassis housing a BIOS and an SCP that presents a virtual BIOS boot media location to the BIOS. The SCP may receive a first physical boot media location from a management system and, when the SCP receives a first BIOS boot image retrieval request from the BIOS that is directed to the virtual BIOS boot media location, it retrieves a first BIOS boot image from the first physical boot media location and provides it to the BIOS. The SCP may then receive a second physical boot media location from the management system and, when the SCP subsystem receives a second BIOS boot image retrieval request from the BIOS that is directed to the virtual BIOS boot media location, it retrieves a second BIOS boot image from the second physical boot media location and provides it to the BIOS.

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.

Abstract: 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 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.

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: 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.
