Abstract
In accordance with at least some embodiments, a system includes an aggregator backplane coupled to a plurality of fans and power supplies and configured to consolidate control and monitoring for the plurality of fans and power supplies. The system also includes a plurality of compute nodes coupled to the aggregator backplane, wherein each compute node selectively communicates with the aggregator backplane via a corresponding interposer board. Each interposer board is configured to translate information passed between its corresponding compute node and the aggregator backplane.
Claims9
An interposer board for interfacing a compute node with an aggregator backplane of a server enclosure, the interposer board comprising:
- a printed circuit board (PCB);
- and
- an interposer programmable interface controller (PIC) mounted on the PCB, the interposer PIC being configured to bridge a single-master serial bus topology for communications between the compute node and the interposer board with a multi-master serial bus topology for communications between the interposer board and the aggregator backplane.
A method for interfacing a plurality of compute nodes with an aggregator backplane of a multi-node server enclosure, the method comprising:
- receiving, at each of a plurality of interposer boards and via a single-master serial bus, a fan control signal from a corresponding compute node separate from the interposer board;
- translating, by each such interposer board, the fan control signal received from the corresponding compute node;
- selectively routing, by the interposer board, translated fan control signals to the aggregator backplane via a multi-master serial bus;
- consolidating the translated fan control signals at the interposer board;
- and
- controlling a fan based on the consolidated translated fan control signals.
