Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If hardware settings are reduced to lower power consumption, then power efficiency improves, but server performance deteriorates
Solution Approach 1:
The patent applies dynamics by enabling real-time adjustment of hardware operation modes based on monitoring of load factors. The system dynamically transitions between power-saving and performance modes according to actual server conditions, making the hardware settings flexible rather than static.
Solution Approach 2:
The patent changes hardware parameters (CPU frequency, voltage, FAN speed) based on monitored load factors. By adjusting these parameters in real-time according to actual usage conditions, the system optimizes both power consumption and performance rather than using fixed settings.
2Productivity
If virtualization infrastructure uses auto-scaling to control number of virtual machines, then resource utilization optimizes, but individual hardware settings remain static leading to low power efficiency
Solution Approach 1:
The patent segments the control of hardware resources into two independent layers: auto-scaling controls the number of virtual machines (resource utilization), while the new operation mode setting device controls individual hardware settings (power efficiency). This segmentation allows both objectives to be optimized simultaneously without interference.
Solution Approach 2:
The operation mode setting device acts as an intermediary between the virtualization infrastructure and hardware. It receives load factor information, determines appropriate operation modes, and adjusts hardware settings accordingly, bridging the gap between virtual resource management and physical hardware optimization.
3Device complexity
If hardware operates with fixed settings, then system simplicity is maintained, but power efficiency deteriorates during low load periods
Solution Approach 1:
The system performs self-service by automatically monitoring its own load factors and adjusting hardware operation modes without external intervention. The operation mode setting device autonomously determines when to switch between power-saving and performance modes based on internal monitoring data.
Solution Approach 2:
The system implements feedback by continuously monitoring load factors and using this information to adjust hardware settings. The monitoring unit provides feedback about system state, and the operation mode setting device uses this feedback to make real-time adjustments to operation modes.
Data Source
AI summary
The operation mode setting device includes a storage unit, a monitoring unit, and an HW setting control unit. The storage unit stores a plurality of operation modes of the hardware and power characteristic data including power efficiency PE and a performance index value PIV. The monitoring unit acquires metrics data including a current load factor LF of the hardware in operation. The HW setting control unit consults the power characteristic data to select an operation mode in descending order of the power efficiency PE at the current load factor LF of the metrics data. If the performance index value PIV at the current load factor in the selected operation mode satisfies a predetermined performance requirement, the HW setting control unit causes the hardware to operate in the selected operation mode.
