Solution Overview
Problem
Conventional power management techniques in data processing systems are inefficient in coordinating power consumption among multiple servers sharing a single power source, leading to excessive power consumption and potential power shortages, especially in rack servers and server farms.
Innovation Solution
A power management server and method that utilizes a system management processor with power management logic to communicate and manage power consumption data among server data processing systems, enabling dynamic power allocation and regulation based on static and dynamic priority levels, thereby reducing overall power usage without compromising application performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of server modules in a rack server is increased to improve rack density, then the productivity and data processing capability are improved, but the power consumption increases disproportionately and may exceed the capacity of a single power input/source
Solution Approach 1:
The patent divides the power management system into multiple independent power sources, each capable of supplying power to a subset of server modules. This segmentation allows the system to scale power capacity by adding more power sources rather than increasing the load on a single power source, thereby supporting higher productivity without proportional increases in power consumption from a single source.
Solution Approach 2:
The patent implements dynamic power allocation where power sources can be dynamically assigned to different server modules based on current power needs and availability. The system can reconfigure power distribution in real-time, allowing flexible adaptation to changing power requirements as server modules are added or removed, thus managing power consumption efficiently while maintaining high productivity.
2Use of energy by moving object
If conventional power management techniques are used to reduce power consumption by reducing voltage or frequency, then power consumption is reduced, but system performance is compromised and user input is required which may not accurately reflect actual power needs
Solution Approach 1:
The patent implements a feedback mechanism where power management logic continuously monitors the actual power consumption of server modules and uses this information to dynamically adjust power allocation. This feedback loop allows the system to optimize power consumption without compromising performance, as power is adjusted based on actual needs rather than static voltage/frequency reductions that blindly sacrifice performance.
Solution Approach 2:
The system enables server modules to self-report their power requirements and performance status to the power management logic. Each module can autonomously indicate its power needs based on current workloads, allowing the system to allocate power efficiently without requiring user input or manual performance degradation. The modules essentially manage their own power consumption needs through self-service reporting.
3Device complexity
If a single power input/source is used to supply power to all server modules, then the device complexity is reduced, but the adaptability and flexibility to manage power for varying numbers and types of modules are limited
Solution Approach 1:
The patent designs power sources and power management logic that can universally interface with different types and numbers of server modules. Each power source is designed to be flexible in its output configuration, and the power management logic can dynamically adapt to various module types and quantities. This multi-functionality allows the same power distribution system to handle diverse configurations without requiring complex custom wiring or control logic for each scenario.
4Adaptability or versatility
If power management logic dynamically allocates power based on priority levels, then the adaptability and responsiveness to different power scenarios are improved, but the device complexity increases due to additional communication and control mechanisms
Solution Approach 1:
The patent combines the power management logic with the existing system management processor in each server module, eliminating the need for separate dedicated power management hardware. The communication port used for general system management is also used for power management communications, merging multiple functions into existing infrastructure. This reduces the overall device complexity while maintaining the adaptability of dynamic power allocation based on priority levels.
