Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Components in servers operating at low temperatures, typically between −5 C.° and −40 C.°, face starting issues, leading to performance degradation.
Innovation Solution
The implementation of heaters disposed on critical components, controlled by a heating manager to raise the temperature of these components to their operational thresholds before initiating the server's startup, ensuring all components function correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the server operates at low temperature environment (−5°C to −40°C), then energy consumption is reduced and cooling costs are lowered, but some components are unable to start and work properly
Solution Approach 1:
The heater is activated before the component is started to preheat the component to a temperature suitable for operation. The heating manager detects low temperature conditions and initiates heating in advance, ensuring the component reaches its starting temperature threshold before attempt to start the component, thus resolving the contradiction between low-temperature operation and component starting reliability
Solution Approach 2:
A heating manager is introduced as an intermediary component that mediates between the low-temperature environment and the component starting process. The heating manager detects temperature conditions and controls heater activation, acting as a bridge that enables components to start reliably in cold environments without compromising the overall low-temperature operation benefits
2Reliability
If heaters are activated to preheat components before startup, then component starting reliability is improved, but device complexity and energy consumption increase
Solution Approach 1:
The heating manager autonomously detects temperature conditions and controls heater activation without requiring external intervention or complex control systems. The system self-monitors component temperatures and automatically initiates heating when needed, reducing device complexity while maintaining component starting reliability
Solution Approach 2:
The heating manager serves multiple functions: it acts as a temperature sensor, a control unit, and a coordinator for the heating process. By consolidating these functions into a single component, the system avoids the need for separate complex control mechanisms, thereby improving reliability without proportionally increasing device complexity
3Reliability
If heaters are used to warm components, then component starting reliability is improved, but energy consumption increases
Solution Approach 1:
The heater is activated periodically or intermittently based on temperature monitoring rather than continuously. The heating manager checks temperature conditions and activates heating only when components approach their starting temperature threshold, reducing unnecessary energy consumption while ensuring components are warmed sufficiently for reliable starting
Solution Approach 2:
The system applies partial heating action by warming only the specific components that require it for starting, rather than heating the entire server environment. This targeted approach minimizes energy consumption by focusing thermal energy only where necessary to achieve component starting reliability

AI summary
A method of starting a server at a low temperature is provided. The server includes N first components, N heaters, and M second components. Each heater is disposed in one of the first components. A lowest starting temperature of each first component is higher than a lowest starting temperature of each second component. In the method, a first temperature of each first component and a second temperature of each second component are obtained in real-time. The N heaters are turned on for a predetermined time duration when it is determined that at least one of the first temperatures and the second temperatures is less than a first predefined temperature. The N heaters are turned off after the predefined time duration. The N first components and the M second components are started after the N heaters are turned off. A server is also provided.
