Solution Overview
Problem
Information processing apparatuses with 2×N Power Supply Units (PSUs) face difficulties in operating processors at performance levels commensurate with the power supply capabilities, especially due to constraints and specifications, limiting operating frequency and throughput even with redundant power configurations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operating frequency of the processor is controlled to match the power suppliable by N PSUs in a two-system power reception configuration, then the system can maintain operation during power failures, but the processor throughput and performance are limited
Solution Approach 1:
The patent applies dynamics by making the processor operating frequency adjustable rather than fixed. The frequency is dynamically changed based on the actual power supply status - operating at a first frequency when both power source systems are normal, and switching to a second, lower frequency when one system fails. This allows the system to optimize between performance and reliability according to real-time conditions.
Solution Approach 2:
The patent changes the operating frequency parameter of the processor based on power supply conditions. When both power source systems are functioning, the processor operates at a higher frequency for maximum performance. When one system fails, the frequency is reduced to match the power capacity of the remaining N PSUs, ensuring continuous operation without exceeding power limits.
2Productivity
If the processor operates at higher frequencies to maximize throughput, then performance is improved, but the system cannot maintain operation during power failures with limited power supply capacity
Solution Approach 1:
The system dynamically adjusts the operating frequency based on power availability. When both power source systems are normal, the processor can operate at higher frequencies to maximize throughput. Upon detecting a power failure in one system, the frequency is automatically reduced to ensure the power consumption remains within the capacity of the remaining N PSUs, thereby maintaining operational reliability.
Solution Approach 2:
The patent implements feedback by monitoring the status of power source systems and using this information to adjust the processor operating frequency. The control apparatus detects when one of the two power source systems fails and responds by changing the frequency to match the reduced power supply capacity, creating a closed-loop control system that balances performance and reliability.
3Use of energy by stationary object
If the operating frequency is reduced to match limited power supply capacity, then power consumption is controlled, but the processor throughput and overall system performance decrease
Solution Approach 1:
The system uses dynamic frequency adjustment to match power consumption with available power supply capacity. When both power source systems are functioning, the processor operates at higher frequencies for maximum performance. When one system fails, the frequency is reduced to ensure power consumption does not exceed the capacity of the remaining N PSUs, optimizing the balance between energy usage and performance.
Solution Approach 2:
The operating frequency parameter is changed based on power supply status to control power consumption. The system monitors the number of functioning power source systems and adjusts the frequency accordingly - maintaining higher frequencies when power is abundant and reducing frequencies when power is limited, thereby optimizing power consumption control while minimizing performance impact.
