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.

First claim

What is claimed is:

1 . A system, comprising:
a shared backup power supply coupled to a node, wherein the shared backup power supply includes a first communication interface; and a plurality of loads supported by the node, wherein each load of the plurality of loads includes a second communication interface, the first and second communication interfaces to support peer-to-peer (P2P) communication between the shared backup power supply and the plurality of loads.

2 . The system of claim 1 , comprising a central processing unit (CPU) of the node, the CPU to route the communication between the shared backup power supply and the plurality of loads.

3 . The system of claim 1 , wherein the first and second communication interfaces are peripheral component interconnect express (PCIe) interfaces.

4 . The system of claim 1 , wherein the second communication interface supports P2P communication among the plurality of loads.

5 . The system of claim 1 , wherein the communication includes status and activity information.

6 . The system of claim 1 , the shared backup power supply to provide backup power to the plurality of loads in response to an interruption of a primary power supply.

7 . The system of claim 1 , wherein the shared backup power supply includes a controller and wherein the controller includes the first communication interface.

8 . The system of claim 1 , wherein the plurality of loads each include a controller and wherein the controller includes the second communication interface.

9 . The system of claim 1 , wherein the plurality of loads includes an array controller and a storage device and wherein the storage device includes a dual in-line memory module (DIMM) and a non-volatile dual in-line memory module (NVDIMM).

10 . A system comprising,
a shared backup power supply to provide backup power to a plurality of loads of a node, wherein the shared backup power supply includes a control module that includes a first communication interface; and an array controller coupled to the plurality of loads, the array controller to manage the plurality of loads and wherein the array controller includes a second communication interface, the first and second communication interfaces to support peer-to-peer (P2P) communication between the shared backup power supply and the plurality of loads.

11 . The system of claim 10 , wherein the first and second communication interfaces are peripheral component interconnect express (PCIe) interfaces.

12 . The system of claim 10 , wherein the first communication interface of the shared backup power supply and the second communication interface of the array controller are communicatively coupled to a central processing unit (CPU) of the node.

13 . The system of claim 12 , wherein the CPU supports P2P communication between the shared backup power supply and the plurality of loads and wherein the CPU supports P2P communication among the plurality of loads.

14 . A non-transitory machine-readable storage medium encoded with instructions executable by a processor, the machine-readable storage medium comprising instructions to:
send a request from a shared backup power supply to a plurality of loads of a node using a peer-to-peer (P2P) communication protocol; and receive, by the shared backup power supply, a response from the plurality of loads using the P2P communication protocol, the response identifying a subset of the plurality of loads that are to be protected by the shared backup power supply.

15 . The non-transitory machine-readable storage medium of claim 14 , comprising instructions to:
route the communication between the shared backup power supply and the plurality of loads via a central processing unit (CPU) of the node, wherein the CPU supports P2P communication between the shared backup power supply and the plurality of loads, and wherein the communication includes activity and status information of the shared backup power supply and the plurality of loads.
