1. A system comprising:

  • multiple backup power sources; and

    a centralized controller external to the backup power sources and to multiple nodes, the centralized controller to;

    receive a communication associated with the multiple nodes, via a communication bus, the communication indicating a number of hardware loads supported by the multiple nodes;

    communicate with the backup power sources;

    determine which of the backup power sources is to deliver power to the multiple nodes based on the received communication associated with the multiple nodes and the communicating with the backup power sources; and

    control the backup power sources to deliver power to the multiple nodes based on the determination, the power delivery being via an electrically conductive path distinct from the communication bus;

    a software-based virtual controller operating on a chassis manager external to the backup power sources, the centralized controller, and the multiple nodes, the virtual controller to communicate with each of the nodes, wherein the virtual controller transmits the communication to the centralized controller via the communication bus, and the communication includes the number of hardware loads supported by the multiple nodes; and

    the centralized controller further comprising;

    a register to hold a value corresponding to the number of hardware loads supported by the multiple nodes, and the centralized controller to determine charge available at the backup power sources.
