Dynamic Power Supply State Transition for Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information handling systems, power management is inefficient due to redundant power supplies operating suboptimally when loads are small, leading to increased power consumption and reduced efficiency, and there is a need for dynamic adjustment of power supply units based on demand and redundancy policies.
Innovation Solution
A method and system that determine the power requirements and capacity of online, redundant, and standby power supply units, allowing for the transition of power supply units between online, redundant, and standby states to optimize power usage and maintain redundancy, including transitioning online units to standby when capacity exceeds requirements and standby units to online when demand exceeds capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple redundant power supplies are brought online and share power requirements, then reliability is improved, but power efficiency deteriorates when load is small
Solution Approach 1:
The system dynamically transitions power supply units between online, redundant, and standby states based on real-time power capacity comparisons. When online power supply capacity exceeds power requirements, excess units transition to standby; when capacity is insufficient, standby units transition to online. This dynamic state management resolves the contradiction by adapting the system configuration to actual load conditions.
Solution Approach 2:
The system changes the operational state parameter of power supply units based on power capacity analysis. By monitoring and comparing power capacity against power requirements, the system adjusts the number of active power supplies, thereby changing the operational parameters to optimize both reliability and efficiency under different load conditions.
2Reliability
If all power supplies operate simultaneously to provide redundancy, then system reliability is improved, but device complexity increases
Solution Approach 1:
The system implements feedback control by continuously monitoring power capacity and power requirements, then adjusting the operational state of power supply units accordingly. This feedback mechanism automates the management of redundancy, reducing the complexity of manual power supply configuration while maintaining reliable operation through adaptive state transitions.
3Reliability
If power supply units operate at low load, then redundancy is maintained, but efficiency decreases
Solution Approach 1:
The system applies partial action by activating only the necessary number of power supply units required to meet current power demands, rather than running all units at full capacity. By transitioning excess power supplies to standby state, the system ensures adequate redundancy while maintaining high efficiency among active units operating at optimal load levels.

AI summary
Systems and methods for power management in an information handling system are disclosed. A method may include determining a power requirement of resources configured to receive power from a plurality of power supply units including one or more online power supply units, one or more redundant power supply units, and one or more standby power supply units. The method may also include determining a power capacity of the one or more online power supply units. The method may additionally include determining if the power capacity of the one or more online power supply units exceeds the power requirement of the resources. The method may further include transitioning at least one of the power supply units based on such determining steps.
