Patent ID: 8688394

Claim:
A computer implemented method for managing a plurality of power supplies in a data center, the method comprising: a server summing input alternating current (AC) power of a power supply, among the plurality of power supplies, to a total AC power of the data center, wherein the total AC power of the data center is a sum of each AC power of the plurality of power supplies, wherein the AC power of the power supply is a discrete AC power value of the power supply; the server summing output direct current (DC) power of the power supply to a total DC power of the data center, wherein the DC power of the power supply is a discrete DC power value of the power supply; the server reporting a ratio of total AC power to total DC power as a data center power conversion efficiency; the server setting an alarm level for each of the plurality of power supplies, wherein the alarm level is a power supply efficiency threshold; the server determining on a scheduled basis, that a real-time power efficiency level is below the power supply efficiency threshold; and the server, responsive to a determination that the real-time power efficiency level is below the power supply efficiency threshold, remedying the power supply.
