Abstract: In a data center which includes a plurality of servers, a discovery computer, a power measurement system (PMS), and a plurality of power-circuits which supply power to the servers, the discovery computer performs the following actions for each server. It transmits a first command to the server causing the server to start generating a power consumption signature if the server is able to do so. Upon receiving a SUCCESS response from the server, it instructs the PMS to start measuring the power consumption from each power-circuit. After a prescribed interval of time has elapsed, it collects the measurements from the PMS and analyzes the measurements to look for the presence of the signature. Upon detecting the signature in the measurement taken from a particular power-circuit, the discovery computer concludes that the server is connected to the particular power-circuit and creates a mapping there-between.

Abstract: A system in one general embodiment includes a waveguide structure comprising a core of an alloy of Group III-V materials surrounded by an oxide (which may include one or more Group III-V metals), wherein an interface of the oxide and core is characterized by oxidation of the alloy for defining the core. A method in one general approach includes oxidizing a waveguide structure comprising an alloy of Group III-V materials for forming a core of the alloy surrounded by an oxide.
