Dynamic Power Cap Adjustment for Server Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices face challenges in managing power consumption as component usage varies, leading to inefficiencies and potential exceedance of power limits, especially in servers and datacenters where power caps are prescribed due to external or user-imposed constraints.
Innovation Solution
A power management system that dynamically monitors and adjusts power caps for various components based on their usage patterns, reallocating power to optimize performance while maintaining overall power consumption within prescribed limits by increasing caps for frequently used components and decreasing them for less active ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power caps are increased for frequently used components to improve performance, then system performance is improved, but overall power consumption exceeds limits
Solution Approach 1:
The patent implements dynamic power cap adjustment where power caps for individual components are not fixed but are continuously modified based on real-time monitoring of component usage patterns. The system transitions from static power allocation to dynamic power allocation, allowing power caps to adapt their values according to actual component utilization, thereby resolving the contradiction between maintaining performance and controlling overall power consumption.
Solution Approach 2:
The patent applies different power cap values to different components based on their specific usage patterns rather than applying a uniform power cap across all components. Each component receives a customized power cap that reflects its actual utilization, allowing frequently used components to receive higher power allocation while less active components receive lower allocation, thus optimizing the balance between performance and power consumption at the component level.
2Loss of energy
If power caps are decreased for less active components to reduce overall power consumption, then power efficiency is improved, but performance of those components degrades
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors component usage patterns and adjusts power caps accordingly. The monitoring system provides feedback about actual component utilization, and this feedback drives the dynamic adjustment of power caps. This closed-loop control ensures that power caps are optimized based on real-time conditions, improving power efficiency for less active components while maintaining adequate performance through continuous adaptation.
3Use of energy by moving object
If fixed power caps are assigned to components, then power consumption is controlled within limits, but performance optimization is prevented due to varying usage patterns
Solution Approach 1:
The patent transforms the static power cap assignment into a dynamic adjustment mechanism. Instead of fixed power caps that cannot adapt to changing usage patterns, the system continuously monitors component utilization and adjusts power caps in real-time. This dynamic approach maintains power consumption control while simultaneously enabling performance optimization by adapting to varying usage patterns across different components and time periods.

AI summary
A system has a plurality of electronic components that are powered by a power source, and each of the components is associated with a respective power cap. The system further has logic configured to monitor power consumption of the electronic components over a duration and dynamically adjust at least one power cap associated with at least one of the electronic components based on the monitored power consumption.
