Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the host controls heat dissipation based on temperature readings from the storage device, then the heat dissipation mechanism can be activated, but the response is delayed because the temperature read command is issued at fixed time intervals rather than continuously monitoring
Solution Approach 1:
The storage device proactively calculates and prepares the working temperature using multiple temperature sensors and a composite temperature algorithm before the host requests temperature information. This preliminary temperature assessment ensures that when the host issues a temperature read command, the storage device can immediately provide accurate temperature data, enabling timely heat dissipation activation without waiting for the next fixed-time monitoring interval.
2Measurement precision
If the storage device uses multiple temperature sensors with composite temperature algorithm, then the temperature measurement accuracy is improved, but the device complexity increases
Solution Approach 1:
The temperature monitoring function is segmented into multiple independent temperature sensors, each monitoring different locations within the storage device. This segmentation allows the system to capture temperature variations across different regions, and the composite temperature algorithm processes these segmented measurements to determine the overall working temperature, improving measurement accuracy while keeping each sensor simple and modular.
Solution Approach 2:
The multiple temperature sensors serve a universal purpose of monitoring different thermal zones within the storage device. Rather than requiring separate monitoring systems for different components, the same temperature sensing and calculation mechanism handles thermal monitoring across the entire device, simplifying the overall system architecture while improving comprehensive temperature measurement accuracy.
3Temperature
If the storage device decreases data accessing speed to prevent continuous temperature increase, then the working temperature can be controlled, but the server operation speed decreases
Solution Approach 1:
The storage device continuously monitors its working temperature using multiple sensors and provides temperature feedback to the host. This real-time temperature feedback enables the host to dynamically adjust the heat dissipation mechanism's operation, activating cooling measures only when necessary. This feedback loop allows the system to maintain optimal temperatures without unnecessarily reducing data accessing speed, preserving server productivity while preventing thermal issues.

AI summary
A working temperature calculation method for a storage device of a server is provided. Firstly, n detected temperatures are converted into n transformed temperatures according to a composite temperature algorithm. If all of the n transformed temperatures are lower than a strengthen heat dissipation trigger temperature, the lowest temperature of the n transformed temperatures is set as a working temperature of the storage device. If at least one of the n transformed temperatures is higher than the strengthen heat dissipation trigger temperature, the highest temperature of the n transformed temperatures is set as the working temperature. When the storage device receives a temperature read command from the host, the storage device sends an information about the working temperature to the host, and the host controls a heat dissipation mode of the heat dissipation mechanism according to the working temperature.
