Performance conserving method for reducing power consumption in a server system
ActiveUS7444526B2Constraining activityReduce frequencyEnergy efficient ICTVolume/mass flow measurementData processing systemStandby power
A method for managing power in a data processing system having multiple components includes determining a power budget for the system. Activity levels during a forthcoming time interval are then predicted for each of the components. Using the predicted activity levels, the power budget is allocated among the system components. An activity limit is then established for each component based on its corresponding portion of the power budget. The activity of a component is then monitored and, if the component's activity exceeds the component's corresponding activity limit, constrained. Determining the predicted level of activity may include determining a predicted number of instructions dispatched by a processor component or a predicted number of memory requests serviced for a system memory component. Allocating the power budget includes allocating each component its corresponding standby power and a share of the system power available for dynamic powering based on the expected levels of activity.

ActiveUS20070260897A1Effective distributionVolume/mass flow measurementHardware monitoringInformation processingModularity
An information handling system includes modular processing resources, each having a main processor, system memory, and preferably a service processor resource. A management resource coupled to a service processor resource evaluates a system power budget and allocates power to a processing resource by indicating a critical power level. The processing resource determines a warning power level based on the critical power level and monitor its actual power consumption. If actual power consumption exceeds the critical power level, the processing resource is powered down. If actual power consumption exceeds the warning power level, the processing resource throttles its performance to conserve power and requests a power allocation increase. If actual power consumption is below the warning power level, the processing resource may request a reduction in allocated power.

Power profiling application for managing power allocation in an information handling system
A method, system, and software instructions for allocating power in a information handling system are operable to respond to a power profiling request by transitioning a processing resource to a first power consumption state and obtaining and storing a first power consumption value. The first power consumption value is then retrieved and used to allocate power to the first processing resource in response to a power on request. The first power consumption state may be a state in which power consumption approximates a maximum power consumption. The processing resource may be further transitioned to a second power consumption state and a second power consumption value obtained. The second power consumption state may be a reduced performance state. Thereafter, responsive to determining that the system lacks sufficient power budget to fulfill a pending request for power, the processing resource is throttled and power is allocated using the second power consumption value.

Low power consumption quick charge for wireless device
The current draw of a wireless device, e.g., a cordless telephone, is minimized for a cradled remote handset drawing power from an AC outlet. This allows a greater portion of the total current amperage provided by the AC to DC converter to be allowed to charge the battery in the remote unit, and reduces the overall maximum or peak value of the current draw of the wireless device. With an improved peak power budget, a smaller (and presumably less expensive) AC to DC adapter than otherwise necessary may be used to power the wireless device. In one aspect, sniff operations of the remote handset are disabled or otherwise suppressed while the remote handset is in the cradle of the base unit, e.g., receiving a quick charge or trickle charge to its battery. In a second aspect, sniff operations of the base unit are disabled or otherwise suppressed while the remote handset is in the cradle of the base unit. In a last aspect, the charging mode of the battery in the remote handset of a wireless device changes based on activity in the remote handset.

System and method for statistical control of power dissipation with host enforcement
The power budgeter controls the rate of data flow in one or more transceivers among a plurality of transceivers. The power budgeter monitors aggregate transceiver activity (data flow) during a predefined period, and limits transceiver data transmit and receive rates during times when the aggregate transceiver activity would otherwise exceed a predefined threshold. If total data flow during the monitored time period exceeds the threshold, data flow through the active transceiver during the next (second) time period is limited. Data flow rates are limited in a transceiver by shutting off transceivers (receiver and / or transmitter) for a specified portion of the second time period. In other types of transceivers, the transmitter and / or receiver may be forced into a low-power idle state or similar operating condition for a specified portion of the second predefined time period.

A group of servers is selected, and the total power allocated to a group of servers is limited to within a group power budget. A separate server power allocation is individually requested for each of a plurality of the servers. Within the constraints of the group power budget, the requested server power allocations are selectively granted for a specified magnitude and duration. The granted server power allocations are also selectively renewed, either automatically or upon request of the servers. Each server that has not received a renewed server power allocation from a group power management entity upon the expiration of the specified duration automatically reduces its own power consumption, such as by the server powering itself off.

A performance measure (e.g., processor speed) for computing components such as servers is optimized by creating models of power consumption versus the performance measure for each server, adding the power models to derive an overall power model, and calculating an optimum set point for the performance measure which corresponds to a power limit on the servers using the overall power model. The set point is then used to set power budgets for the servers based on their power models, and the servers maintain power levels no greater than their respective power budgets. The server power models are preferably created in real time by monitoring power consumption and the performance measure to derive sets of data points for the servers, and performing regression on the sets of data points to yield power models for the servers.
