Abstract: A method and system are disclosed to enable and control over-subscription in a blade/chassis system and to provide the capability to recover in the event of the loss of a redundant power supply. An over-subscription policy is determined by a system administrator and is set in the chassis management module. Information regarding the maximum power allocation needed for each blade being powered by the power supply system is identified by the blade and stored in its VPD or otherwise made available to the chassis management module. The management module of the chassis in which the blades and power supplies are located uses this information to manage the subscription of blades and the over-subscription of blades when appropriate. If throttling is required, the system also allows a predetermined blade priority to be used to identify which blades will be reduced in power.

Abstract: A method and system and calibration technique for power measurement and management over multiple time frames provides responsive power control while meeting global system power consumption and power dissipation limits. Power output of one or more system power supplies is measured and processed to produce power values over multiple differing time frames. The measurements from the differing time frames are used to determine whether or not system power consumption should be adjusted and then one or more devices is power-managed in response to the determination. The determination may compare a set of maximum and/or minimum thresholds to each of the measurements from the differing time frames. A calibration technique uses a precision reference resistor and voltage reference controlled current source to introduce a voltage drop from the input side of a power supply sense resistor calibration is made at the common mode voltage of the power supply output.

Abstract: A method and system are disclosed to enable and control power reduction in a blade/chassis system. A “maximum power reduction” attribute is stored in the VPD of the blade (or can otherwise be input to or retrieved or calculated by the management entity). The management module of the chassis in which the blades and power supplies are located uses this information to manage the power reduction of blades when the system is operating in an over-subscription mode and a power supply fails. If throttling is required, the system knows the amount of power reduction available for each blade and controls the throttling by spreading it out among the blades in the system so that, ideally, no blade will cease operation altogether.
