Location-Based Thermal Management for Information Handling Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal control algorithms for information handling systems do not consider the physical location of resources, leading to inefficiencies due to the application of 'worst case' parameters.
Innovation Solution
An information handling system with a management controller and a thermal table that sets thermal parameters based on the specific location of each resource, using firmware to identify locations and apply appropriate thermal management parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If worst case thermal parameters are applied to all resources, then thermal safety is ensured, but thermal management efficiency deteriorates
Solution Approach 1:
The patent applies local quality by creating location-specific thermal parameters for different physical positions within the information handling system. Instead of using uniform worst-case parameters system-wide, the system defines distinct thermal profiles for resources based on their specific locations (e.g., front vs. rear, top vs. bottom), allowing each resource to be managed with parameters optimized for its local thermal environment.
Solution Approach 2:
The patent segments the thermal management approach by dividing the system into multiple location-based zones. Each zone has its own thermal parameters stored in a thermal table, enabling independent optimization of cooling strategies for different physical regions rather than treating the entire system as a single uniform entity.
2Loss of energy
If location-specific thermal parameters are applied, then thermal management efficiency improves, but system complexity increases
Solution Approach 1:
The patent achieves universality by implementing a comprehensive thermal table that serves multiple functions: it stores location identifiers, resource types, and thermal parameters all in one centralized structure. This multi-functional approach consolidates what could be multiple separate management systems into a single unified thermal management mechanism, reducing overall system complexity despite the increased granularity of control.
Solution Approach 2:
The system implements self-service by automatically determining the thermal parameters for each resource based on its location without requiring manual configuration. The firmware or management controller autonomously queries the thermal table using the resource's location identifier and applies the appropriate parameters, eliminating the need for complex manual setup and maintenance of location-specific thermal profiles.

AI summary
A method may include identifying a respective location of a particular information handling resource within an information handling system, based on the respective location, reading an entry from a thermal table comprising thermal parameters for thermal management of one or more information handling resources of the information handling system based on respective locations of the one or more information handling resources within the information handling system, and applying at least one thermal parameter from the entry for thermal management of the particular information handling resource.
