Power-Managed Server Dynamic Power Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data processing systems face challenges in managing power consumption efficiently, especially in rack servers with multiple modules, where power distribution is inadequate, leading to excessive energy use and potential power shortages, and existing power management techniques require explicit user input or rely on external events, failing to coordinate power consumption among multiple systems.
Innovation Solution
A power-managed server system with a communication port and system management processor that transmits and receives power management data to coordinate power consumption among multiple server data processing systems, allowing for dynamic priority adjustments and throttling to optimize power usage based on actual needs, thereby reducing overall power requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of server modules in a rack server is increased to improve computing capacity, then productivity is improved, but power consumption increases disproportionately and may exceed available power supply capacity
Solution Approach 1:
The patent implements dynamic power management by continuously monitoring power consumption of individual server modules and dynamically adjusting their operational states. The system transitions modules between active, idle, and powered-off states based on real-time workload and power availability, enabling the rack to handle higher computing capacity without proportional power increases.
Solution Approach 2:
Each server module includes integrated power management logic that autonomously monitors its own power consumption and communicates with the central power management system. The system self-regulates power distribution across modules without external intervention, automatically balancing power allocation to prevent total power consumption from exceeding supply capacity while maintaining required computing performance.
2Use of energy by moving object
If conventional power management techniques are used that require explicit user input or external events, then power consumption can be reduced, but the system cannot coordinate power consumption among multiple systems automatically
Solution Approach 1:
The patent implements a centralized power management system that continuously collects power consumption data from all server modules via a communication network. The system processes this feedback information and automatically generates power management commands, adjusting power allocation in real-time based on actual power usage patterns, workload demands, and available power supply capacity, eliminating the need for manual user input or external event triggers.
Solution Approach 2:
The power management system serves multiple functions simultaneously: it monitors power consumption across all modules, coordinates power allocation among multiple systems, communicates with the power supply unit, and dynamically adjusts operational states. This universal power management architecture handles the entire power coordination task automatically without requiring separate manual interventions for each function.
3Device complexity
If a single power input supplies power to all server modules, then device complexity is reduced, but the system cannot provide sufficient power when all modules operate at maximum capacity simultaneously
Solution Approach 1:
The system maintains a simple single-power-input architecture but dynamically manages power distribution through intelligent control. The power management system continuously adjusts the operational state of individual modules, transitioning them between active, idle, and powered-off states based on workload demands and power availability, enabling the system to operate successfully with a single power input without requiring complex multi-source power distribution infrastructure.
