Fail-Safe Power Limits for Server Performance During MM Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power management in information handling systems reduces performance significantly when power supply units are at risk of overload, leading to undesirable user experiences due to extremely low processor clock rates and reduced processing capacity.
Innovation Solution
Implementing a fail-safe power limit (FSPL) computed by a management module and distributed to components, allowing them to operate at higher performance levels by optimizing power distribution based on historical usage and user-defined priorities, thereby utilizing more available power without overloading the power supply units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power management reduces all components to minimum power level to prevent power supply overload, then power supply safety is improved, but system performance deteriorates significantly
Solution Approach 1:
The patent applies local quality by distributing differentiated power limits to individual components rather than uniformly reducing all components to minimum power levels. The management module calculates and assigns specific power limits (P1, P2, P3) to different components based on their historical power consumption patterns and current system state, allowing each component to operate at its optimal safe power level while maintaining overall system performance.
2Reliability
If power limits are reduced to bare minimum to ensure power supply safety, then power supply overload prevention is improved, but available power utilization deteriorates
Solution Approach 1:
The patent implements dynamics by continuously monitoring actual power consumption and dynamically adjusting power limits assigned to components. The management module recalculates power limits based on real-time power consumption data and historical patterns, allowing the system to safely utilize more available power from the power supply unit while preventing overload conditions. This dynamic adjustment enables the system to operate closer to the power supply's maximum safe capacity rather than守着 a static conservative limit.
3Reliability
If uniform minimum power limits are applied to all components, then power supply protection is improved, but power distribution optimization deteriorates
Solution Approach 1:
The patent applies local quality by distributing differentiated power limits to individual components rather than uniformly reducing all components to minimum power levels. The management module calculates and assigns specific power limits (P1, P2, P3) to different components based on their historical power consumption patterns and current system state, allowing each component to operate at its optimal safe power level while maintaining overall system performance.
Solution Approach 2:
The patent implements preliminary action by pre-calculating and storing historical power consumption data for each component before power supply issues occur. The management module uses this historical data to establish baseline power consumption patterns and pre-determine appropriate power limits, enabling rapid response when power supply conditions change without requiring complex real-time calculations during critical moments.

AI summary
A fail-safe power limit (FSPL) can be applied to components that lose communication with a management module (MM) to determine a safe power level at which to operate. The FSPL may be computed by the management module (MM) for the information handling system and distributed to components in the information handling system. By computing a FSPL and transmitting the FSPL to the components, a larger amount of the available power can be used by the components. This allows the components to continue operating at performance levels closer to or equivalent to levels available when the management module (MM) is operating normally. The FSPL may be updated at set times and/or on a periodic schedule such that the FSPL used by the components when communication is lost with the management module (MM) reflects a recent operating state of the components.
