1. A method for operating a discovery system in a data center having a plurality of servers powered via a plurality of power supply outlets, the method comprising of steps of:
- selecting a feasible set of candidate power supply outlets for at least one of the servers connected to at least one of the plurality power supply outlets, the feasible set being a subset of the plurality of power supply outlets;
collecting power consumption data for the feasible power outlets over time and central processing unit utilization data for the at least one server during an overlapping time by a data collection module of the discovery system;
storing the information collected by a data collection module of the discovery system;
correlating the CPU utilization data to the power consumption data for candidate pairings of feasible power supply outlets with the at least one server by a correlation engine of the discovery system according to a first set of metrics;
determining whether correlations according to the first set of metrics indicate that the at least one server is associated with one or more of the set of feasible power supply outlets; and
correlating the CPU utilization data to the power consumption data by the correlation engine according to a second set of metrics when the correlation according to the first set of metrics is insufficient to determine an association.

12. A system for automatically discovering the connectivity of servers to a plurality of power outlets in a data center comprising:
-
a data collection module interfaced with power supply outlets and IT equipment, the data collection module operable to collect actual power usage for power supply outlets and CPU usage from IT equipment; a data store having the information collected by the data collection module; and a correlation engine operable select a feasible set of candidate power supply outlets and correlate the CPU usage data with actual power usage data to identify a piece of IT equipment connected to one of the power supply outlets, the feasible set of power supply outlets being a subset of the plurality of power supply outlets, wherein the correlation engine determines whether correlations according to a first set of metrics indicate that the at least one server is associated with one or more of the set of feasible power supply outlets, and in addition determines correlations according to a second set of metrics when the correlations according to the first set of metrics are insufficient to determine an association. - View Dependent Claims (13, 14)
