In an implementation, airflow provisioning in an area by a plurality of fluid moving devices is managed through assignment of the fluid moving devices to monitor and regulate conditions at respective subsets of a plurality of locations based upon determined influence levels of the fluid moving devices on the respective locations to meet a predefined cooling influence redundancy level. The predefined cooling influence redundancy level for a particular location identifies a number of the fluid moving devices that are to monitor and regulate a condition at the particular location.
