Abstract

A rack-mount system includes a data center manager and a rack which contains a plurality of electronic devices, a rack management controller and a plurality of power supplies. Before a specific electronic device performs a booting procedure, related booting parameters of the specific electronic device are accessed. The data center manager or the rack management controller is configured to calculate the amount of power required for the specific electronic device to perform the booting procedure according to the accessed booting parameters. The rack management controller is configured to control the number of activated power supplies among the plurality of power supplies according to the calculated amount of power.

First claim

What is claimed is:

1 . A method of performing power management in a rack-mount system, the rack-mount system including a plurality of electronic devices and a plurality of power supplies disposed in a rack, the method comprising:
accessing booting parameters of a specific electronic device among the plurality of electronic devices before the specific electronic device performs a booting procedure; calculating an amount of power required for the specific electronic device to perform the booting procedure according to the accessed boot parameters; and controlling a number of activated power supplies among the plurality of power supplies according to the calculated amount of power required for the specific electronic device to perform the booting procedure.

2 . The method of claim 1 , further comprising:
the specific electronic device sending a booting notification to a rack management controller (RMC) of the rack-mount system before performing the booting procedure; and the RMC accessing the booting parameters of the specific electronic device after receiving the booting notification; the RMC calculating the amount of power required for the specific electronic device to perform the booting procedure according to the booting parameters; and the RMC controlling the number of activated power supplies among the plurality of power supplies according to the calculated amount of power required for the specific electronic device to perform the booting procedure.

3 . The method of claim 2 , further comprising:
the RMC sending a booting approval after controlling the number of activated power supplies among the plurality of power supplies; and the specific electronic device performing the booting procedure after receiving the booting approval.

4 . The method of claim 1 , further comprising:
the specific electronic device sending a booting notification to a rack management controller (RMC) of the rack-mount system before performing the booting procedure; and the specific electronic device performing the booting procedure when a predetermined period has elapsed after sending the booting notification.

5 . The method of claim 1 , further comprising:
the specific electronic device sending a booting notification to a data center manager (DCM) of the rack-mount system before performing the booting procedure; the DCM sending an inquiry message to a rack management controller (RMC) of the rack-mount system after receiving the booting notification; the RMC sending the booting parameters of the specific electronic device to the DCM after receiving the inquiry message; the DCM calculating the amount of power required for the specific electronic device to perform the booting procedure according to the booting parameters of the specific electronic device and notifying the RMC of the calculated amount of power required for the specific electronic device to perform the booting procedure; and the RMC controlling the number of activated power supplies among the plurality of power supplies according to the amount of power required for the specific electronic device to perform the booting procedure and notifying the DCM of a status of the plurality of power supplies; the DCM determining whether a booting approval should be sent to the specific electronic device according to the status of the plurality of power supplies; and the specific electronic device performing the booting procedure when receiving the booting approval.

6 . The method of claim 1 , further comprising:
the specific electronic device sending a booting notification to a rack management controller (RMC) of the rack-mount system or to a data center manager (DCM) of the rack-mount system using an intelligent platform management interface (IPMI) via a baseboard management controller (BMC) before performing the booting procedure, or sending the booting notification to the RMC or to the DCM using a simple network management protocol (SNMP) via a network management software module before performing the booting procedure.

7 . The method of claim 1 , further comprising:
a rack management controller (RMC) of the rack-mount system monitoring an electronic behavior of the rack and an operational status of the plurality of power supplies after controlling the number of activated power supplies among the plurality of power supplies; and the RMC adjusting the number of activated power supplies among the plurality of power supplies according to the monitored electronic behavior and the operational status.

8 . The method of claim 1 , wherein:
controlling the number of activated power supplies among the plurality of power supplies according to the calculated amount of power required for the specific electronic device to perform the booting procedure is activating one or multiple power supplies among the plurality of power supplies; and a sum of maximum output power of the activated one or multiple power supplies is equal to or larger than the amount of power required for the specific electronic device to perform the booting procedure.

9 . The method of claim 1 , wherein:
controlling the number of activated power supplies among the plurality of power supplies according to the calculated amount of power required for the specific electronic device to perform the booting procedure is activating one or multiple power supplies among the plurality of power supplies; and a sum of output power of the activated one or multiple power supplies when operating in respective optimized operational ranges is equal to or larger than the amount of power required for the specific electronic device to perform the booting procedure.

10 . A method of performing power management in a rack-mount system, the rack-mount system including a plurality of electronic devices, a plurality of power supplies, a rack management controller (RMC) , and at least one non-RMC controlled power supply disposed in a rack, the method comprising:
a specific electronic device among the plurality of electronic devices performs a booting procedure using power supplied by the non-RMC controlled power supply; the RMC monitoring a status of the at least one non-RMC controlled power supply; and the RMC controlling a number of activated power supplies among the plurality of power supplies according to the status of the at least one non-RMC controlled power supply.

11 . The method of claim 10 , wherein:
the RMC controlling the number of activated power supplies among the plurality of power supplies according to the status of the at least one non-RMC controlled power supply is activating one or multiple power supplies among the plurality of power supplies so as to allow the at least one non-RMC controlled power supply to operate in an optimized operational range.

12 . The method of claim 11 , further comprising:
the RMC monitoring an electronic behavior of the rack and an operational status of the plurality of power supplies after controlling the number of activated power supplies among the plurality of power supplies; and the RMC adjusting the number of activated power supplies among the plurality of power supplies according to the monitored electronic behavior and the operational status.

13 . A method of performing power management in a rack-mount system, rack-mount system including a plurality of electronic devices a plurality of power supplies, and a rack management controller (RMC) disposed in a rack, the method comprising:
the RMC monitoring an electronic behavior of the rack and an operational status of the plurality of power supplies; and the RMC controlling a number of activated power supplies among the plurality of
