Abstract
A system includes a rack, a plurality of shelves, a plurality of shelf-mountable electrical systems, and an inter-shelf power-pooling bus. The inter-shelf power-pooling bus is coupled to a power output of a shelf power supply mechanism on each of the shelves and a power input of a shelf computing device on each of the shelves. The inter-shelf power-pooling bus supplies pooled power from the shelf power supply mechanisms coupled to the inter-shelf power bus to the shelf computing devices coupled to the inter-shelf power-pooling bus.
Claims26
A system, comprising:
- a rack comprising a plurality of shelves;
- a plurality of shelf-mountable electrical systems, wherein respective ones of the plurality of shelf-mountable electrical systems are coupled to respective ones of the shelves, wherein the respective ones of the plurality of shelf-mountable electrical systems comprise one or more chassis, a shelf power supply mechanism configured to receive AC power from a power distribution system and supply DC power, and one or more shelf computing devices;
- an inter-shelf power-pooling bus coupled to the plurality of shelf-mountable electrical systems, wherein for a given shelf-mountable electrical system of the respective ones of the plurality of shelf-mountable electrical systems, the inter-shelf power pooling bus is coupled between:
- a DC power output of a shelf power supply mechanism of the given shelf-mountable electrical system;
- and
- a power input of a shelf computing device of the given shelf-mountable electrical system;
- wherein the inter-shelf power-pooling bus is configured to supply pooled power from the shelf power supply mechanisms coupled to the inter-shelf power bus to the shelf computing devices coupled to the inter-shelf power-pooling bus.
