SYSTEM AND METHOD FOR AUTOMATIC DETERMINATION OF THE PHYSICAL LOCATION OF DATA CENTER EQUIPMENT
First Claim
1. A system for automatic discovery of the physical location of at least one device in a data center, the device having an associated ultrasonic emitter, the system comprising:
- a first set of ultrasonic transducers having known locations in the data center,a first controller associated with the first set of ultrasonic transducers wherein the first controller initiates the generation of an ultrasonic signal from the ultrasonic emitter associated with the device,time of arrival circuitry that generates time of arrival information based on the time of receipt of the ultrasonic signal at each ultrasonic transducer in the first set of ultrasonic transducers,wherein the first controller determines the relative location of the device based on the known location of the first set of ultrasonic transducers within the data center and the time of arrival information associated with each ultrasonic transducer in the first set of ultrasonic transducers.

Abstract
The invention is directed to a system and method for automatic discovery of the physical location of at least one device in a data center, the device having an associated ultrasonic emitter. The system generally includes a plurality of ultrasonic detectors having known locations in the data center. A controller initiates the generation of an ultrasonic signal from an ultrasonic emitter associated with a device under test. Time of arrival circuitry generates time of arrival information associated with each ultrasonic detector based on the time of receipt of the ultrasonic signal. The controller determines the location of the device under test based on the known location of the ultrasonic detectors within the data center and the time of arrival information associated with each ultrasonic detector.
