A method for controlling rotational speed applied to a smart fan includes acquiring environmental temperature from a temperature sensor and radiation intensity of human body from an infrared sensor. A result of analysis is generated by determining whether the acquired environmental temperature is within a predetermined temperature range and the acquired radiation intensity is greater than a predetermined value. A working status of the smart fan can be changed according to the result when the smart fan is in automatic mode.

Examples may include techniques to determine locations of a physical resource in a data center. A data center can include a number of racks having sled spaced. The sled spaces accommodate sleds having one or more physical resources disposed on each sled. The racks and sleds can include a beacon and beacon sensor, respectively, operable to determine a location of the sleds within the data center. Beacons and beacon sensors can exchange signals, a pod controller can receive an information element including indications of the exchanged signals and determine a location of the physical resource within the data center.
