Claim Text:
1. A system, comprising: an enclosure configured to contain a plurality of compute nodes; an airflow controller configured to control a flow of air provided to each of the plurality of compute nodes; wherein the airflow controller is configured to receive unsolicited requests for airflow from each of the compute nodes; wherein the airflow controller is configured to control airflow provided to a given compute node based on the unsolicited airflow requests received from a subset of the compute nodes, including the given node, the subset of the compute nodes being assigned to a same airflow zone by the airflow controller; and a shared communication link coupling the plurality of compute nodes to the airflow controller, wherein the communication link includes a communication link access request signal received by the airflow controller indicating a given compute node has an airflow request, a communication link grant signal asserted by the airflow controller in response to the request signal, and a serial data link configured to propagate the unsolicited airflow requests from the plurality of compute nodes to the airflow controller.
