Power management method of system and related internet data center

A system, comprising:

• a plurality of servers;
• a power supply comprising a plurality of power supply units;
• a rack management controller (RMC) configured to:
• turn on all power supply units in the power supply for supplying power to the plurality of servers after booting-up the system;
• acquire a maximum output power value of the power supply and a conversion efficiency table of the power supply, wherein the conversion efficiency table contains a relationship between a loading rate of the power supply and a conversion efficiency of the power supply;
• measure an average output power of the power supply within a predetermined period;
• divide the average output power of the power supply by the maximum output power of the power supply for providing a real-time conversion efficiency of the power supply;
• determine whether the power supply is currently operating with an optimized conversion efficiency based on the conversion efficiency table and the real-time conversion efficiency of the power supply;
• and
• adjust a number of turned-on power supply units among the plurality of supply units in the power supply according to a predetermined rule when determining that the power supply is not currently operating with the optimized conversion efficiency.

A system, comprising:

• at least one server, comprising:
• a power supply comprising a plurality of power supply units;
• and
• a baseboard management controller (BMC) configured to control an operation of each power supply unit in the power supply for supplying power to the at least one server;
• and
• a rack management controller (RMC) configured to:
• acquire a maximum output power value of the power supply and a conversion efficiency table of the power supply via the baseboard management controller, wherein the conversion efficiency table contains a relationship between a loading rate of the power supply and a conversion efficiency of the power supply;
• measure an average output power of the power supply within a predetermined period;
• divide the average output power of the power supply by the maximum output power of the power supply for providing a real-time conversion efficiency of the power supply;
• determine whether the power supply is currently operating with an optimized conversion efficiency based on the conversion efficiency table and the real-time conversion efficiency of the power supply;
• and
• instruct the baseboard management controller to adjust a number of turned-on power supply units among the plurality of supply units in the power supply according to a predetermined rule when determining that the power supply is not currently operating with the optimized conversion efficiency.
