Abstract: Example implementations relate to coupling volatile memory devices to a power source. In example implementations, data may be copied from a first volatile memory device on a memory module to non-volatile memory. The first volatile memory device may cease to be powered after data is copied from the first volatile memory device to non-volatile memory. After the first volatile memory device has ceased to be powered, data may be copied from a second volatile memory device on the memory module to non-volatile memory. The second volatile memory device may cease to be powered after data is copied from the second volatile memory device to non-volatile memory.

Abstract: Example implementations relate to data transfer using backup power supply. For example, a system includes a shared backup power supply coupled to a node. The system also includes a controller to detect an interruption of primary power supply to the node and isolate a portion of the node from a sequenced shutdown of the node. The controller is further to initiate a transfer of data, utilizing the shared backup power supply, from volatile memory of the node to non-volatile memory of the node.

Abstract: Example implementations relate to backup power communication. For example, a system includes a shared backup power supply coupled to a node, where the shared backup power supply includes a first communication interface. The system also includes a plurality of loads supported by the node, where each load of the plurality of loads includes a second communication interface. The first and second communication interfaces support peer-to-peer (P2P) communication between the shared backup power supply and the plurality of loads.
