Server BIOS Connector Initialization Staggering for Power Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server power-on methods result in high instantaneous power consumption during HDD initialization, leading to potential over-current damage and instability.
Innovation Solution
The method involves using a BIOS to stagger the initialization times of connectors connected to power consumption modules, allowing for delayed power-on and optimizing power distribution by setting a delay time or randomly generating it based on motherboard identification codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all connectors are initialized simultaneously during server power-on, then the system can be quickly brought to operational state, but the instantaneous power consumption peaks and may damage HDD components
Solution Approach 1:
The patent segments the simultaneous initialization process into sequential stages by dividing connectors into multiple groups. Each group is initialized at different time intervals, transforming a single high-power event into multiple lower-power events that occur sequentially rather than simultaneously.
Solution Approach 2:
The patent implements periodic action by initializing connector groups at regular time intervals. The BIOS controller activates each connector group sequentially with predetermined delay periods, creating a rhythmic power-on pattern that distributes power consumption over time rather than concentrating it at one moment.
2Device complexity
If all connectors are initialized simultaneously, then the system setup is simplified, but the superposition of peak power values causes excessive instantaneous power consumption
Solution Approach 1:
The patent segments the connector initialization into organized groups with predetermined activation sequences. This segmentation provides a structured approach that manages complexity through systematic organization rather than random or purely sequential initialization, making the control logic more predictable and manageable.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the initialization sequence and time intervals before the actual power-on process. The BIOS contains predetermined timing parameters and connector group assignments that are established in advance, eliminating the need for complex real-time decision-making during initialization.
3Loss of time
If simultaneous initialization is used, then the power-on process is fast, but the high current may damage the HDD
Solution Approach 1:
The patent uses periodic action with carefully designed time intervals between connector group initializations. These intervals are sufficient to allow power consumption to return to baseline levels before the next group activates, preventing cumulative over-current stress on HDD components while still completing the entire initialization process in a reasonable total time.
Solution Approach 2:
The patent implements beforehand cushioning by introducing deliberate delay periods between connector initializations. These cushioning intervals act as protective buffers that prevent power peaks from overlapping and damaging HDD components, while the overall sequence is optimized to minimize the total time added to the power-on process.

AI summary
A method of powering on a server is provided, wherein the server includes power consumption modules with the same functions, connectors, and a BIOS (Basic Input/Output System). The power consumption modules are connected to the server via the connectors respectively. This method includes the steps as follows. At first, the BIOS detects a delay power-up setting. When the delay power-up setting is detected, the BIOS staggers initialization times of the connectors, so that the connectors can be initialized respectively. When one of the connectors has been initialized, the connector is electrically connected to the corresponding power consumption module, so that the power consumption module can be delayed to be powered on.
