Processor Throttling for Modular Server Cooling Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face overheating issues due to inadequate cooling in modular server chassis, leading to inaccurate temperature sensing and potential system shutdowns, as airflow is diverted to empty sections rather than installed servers, causing sensors to report lower temperatures and resulting in inefficient operation and downtime.
Innovation Solution
A management module generates a throttle signal to reduce the processor's throughput by decreasing its operating speed, which in turn reduces the frequency of information requests from system resources, thereby lowering the operating temperature and ambient temperature within the system, preventing overheating and system failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modular components are easily installed and removed from server chassis, then adaptability and ease of operation are improved, but cooling efficiency deteriorates due to empty sections diverting airflow
Solution Approach 1:
The management module proactively detects empty chassis sections before they cause overheating problems, and preemptively throttles processor operations to reduce heat generation. This preliminary action prevents the cooling efficiency problem from manifesting, rather than reacting after temperature issues arise.
Solution Approach 2:
The system continuously monitors chassis configuration through sensors and airflow detection, providing feedback to the management module. When empty sections are detected, the feedback loop triggers automatic processor throttling to maintain proper cooling, creating a closed-loop control system that adapts to changing chassis configurations.
2Speed
If cooling air flows in empty sections rather than through installed servers, then airflow resistance is reduced, but temperature sensing accuracy deteriorates
Solution Approach 1:
The management module acts as an intermediary between the airflow system and temperature sensors. When it detects that airflow is diverted to empty sections, it mediates by throttling processor operations to reduce heat generation, compensating for the sensors' inability to accurately measure temperatures caused by altered airflow patterns.
Solution Approach 2:
The system replaces reliance on mechanical temperature sensing (which depends on proper airflow) with an electronic control system that detects chassis configuration and actively manages processor throughput. This substitution bypasses the flawed mechanical sensing approach by using electronic monitoring and control.
3Temperature
If processor operating speed is reduced to lower temperature, then temperature control is improved, but system productivity decreases
Solution Approach 1:
The management module applies partial throttling to processor operations - reducing speed only enough to maintain proper temperature levels while preserving as much productivity as possible. This partial action approach avoids complete shutdown while preventing overheating, finding an optimal balance between temperature control and system output.

AI summary
A system and method for indirect throttling of a system resource by a processor are disclosed. An information handling system includes a chassis that receives modular components, a processor disposed in the chassis and a system resource in communication with the processor. A management module associated with the chassis generates a throttle signal that throttles operation of the processor in response to receiving an alarm such that the processor reduces the throughput of the system resource.
