Dynamic power supply management

摘要

In some implementations, a rack management controller can dynamically manage power supply units in a server rack system. For example, the rack management controller can determine how many power supply units should be powered on based on the power requirements of the server rack system. The management controller can configure a power management controller to turn on the determined number of power supply units. The rack management controller can receive status signals from the power supply units in the server rack. The rack management controller can detect when a power supply unit fails based on the status signals. The rack management controller can dynamically reconfigure the power management controller to replace the failed power supply unit by turning on a reserved power supply unit.

1. A method comprising:
determining, by a controller in a server rack system, a minimum amount of power for operating the server rack system;
determining, by the controller, a total number of power supply units coupled to the server rack system;calculating a minimum threshold number of power supply units capable of providing the minimum amount of power;determining a power supply unit configuration based on the threshold number; andsending the power supply unit configuration to a power management controller, wherein the power management controller determines which power supply units to turn on based on the power supply unit configuration.
