System and method for blade information handling system power inventory
First Claim
1. A blade information handling system server comprising:
- a chassis having a power supply associated with plural blade slots, each blade slot operable to accept a blade information handling system and apply power to the blade information handling system;
a chassis management controller interfaced with the power supply and the slots and operable to control the application of power at a slot;
one or more blade information handling systems disposed in the slots and interfaced with the chassis management controller, each blade information handling system having an associated baseboard management controller operable to manage startup to an on state and shut down to an off state of the associated blade information handling system; and
a power inventory module running on each baseboard management controller, the power inventory module operable to perform a first power inventory of the associated blade information handling system in the off state and a second power inventory in the on state.

Abstract
A blade information handling system server prevents excess power demand from blade information handling systems by inventorying the power consumption of each blade information handling system before startup. Another power consumption inventory performed after startup ensures an accurate power consumption inventory for making subsequent startup decision. The baseboard management controller performs the first power consumption inventory with the processing components of the blade information handling system in an off state. The power inventory is communicated to the chassis management controller to obtain authorization to startup based on the power available at the chassis. The second power inventory is performed with the processing components in an on state and forwarded to the chassis management controller for use in subsequent determinations of power available at the chassis.

8. A method for information handling system power management through a chassis that provides power to plural information handling systems, the method comprising:
-
inventorying hardware components of an information handling system for power consumption while the hardware components are in an off state, the inventorying performed with a management processor associated with the information handling system;
communicating the inventoried power consumption to a chassis management controller;
comparing with the chassis management controller the inventoried power consumption, available power at the chassis and the inventoried power of information handling systems in an on state to authorize startup of the information handling system;
initiating startup of the information handling system with the management processor;
re-inventorying the hardware components for power consumption while the hardware components are in an on state; and
communicating the re-inventoried power consumption to the chassis management controller. - View Dependent Claims (9, 10, 11, 12)

13. A system for information handling system power management through a chassis that provides power to plural information handling systems, the system comprising:
-
an inactive power estimator operable to inventory power consumption associated with processing components of an information handling system while the processing components are in an inactive state and to communicate the inventoried power consumption to a chassis management controller to obtain authorization to startup the processing components; and
an active power estimator operable to inventory power consumption associated with processing components with the processing components in an active state and to communicate the inventoried power consumption to a chassis management controller for use in managing chassis power. - View Dependent Claims (14, 15, 16, 17, 18)
