Abstract
A method for power management by a rack management controller (RMC) of a server rack includes collecting power consumption data from a first baseboard management controller (BMC) of a first server in the server rack and sending the power consumption data to a management server. The RMC receives power requirements from the management server and determines a power setting based on the power consumption data and the power requirements. The RMC requests the first BMC to limit power consumption of the first server according to the power setting.

A method for power management by a rack management controller (RMC) of a server rack, comprising:
- collecting power consumption data from a first baseboard management controller (BMC) of a first server in the server rack;
- sending the power consumption data to a management server;
- receiving power requirements from the management server;
- determining a power setting based on the power consumption data and the power requirements;
- and
- requesting the first BMC to limit power consumption of the first server according to the power setting.
A method for power management by a baseboard management controller (BMC) of a first server in a server rack, comprising:
- receiving a request from a rack management controller (RMC) of the server rack for power consumption data of the first server;
- reading processor power data from at least one processor model-specific register (MSR);
- reading memory power data from at least one memory MSR;
- reading motherboard power data from a motherboard power converter sensor;
- determining the power consumption data based on the processor, memory, and motherboard power data;
- and
- sending the power consumption data to the RMC.
A system for power management, comprising:
- a first server with a first baseboard management controller (BMC);
- and
- a rack management controller (RMC) configured to:
- collect power consumption data from the first BMC of the first server;
- send the power consumption data to a management server;
- receive power requirements from the management server;
- determine a power setting based on the power consumption data and the power requirements;
- and
- request the first BMC to limit power consumption of the first server according to the power setting.
