Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for limiting rack power consumption in data centers with numerous nodes are inefficient due to the time-consuming process of setting and transmitting power consumption limitation values to each node, especially in large-scale setups.
Innovation Solution
A method and apparatus that determine a rack power consumption limitation threshold and current power consumption mode, allowing a rack management controller to automatically calculate and transmit power consumption thresholds to each node, enabling efficient power reduction without user intervention across multiple racks and nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually determines and transmits power consumption limitation values to each node individually, then the power consumption limitation can be implemented, but the time consumption and operational complexity increase significantly due to the large number of racks and nodes
Solution Approach 1:
The patent merges the power consumption limitation control for all nodes in a rack into a single centralized operation. The rack management controller receives one power consumption limitation value from the user and automatically distributes it to all nodes in the rack, transforming multiple individual operations into one unified operation that achieves the same power limitation effect across all nodes.
Solution Approach 2:
The rack management controller serves as an intermediary between the user and the nodes. Instead of the user directly configuring each node, the user configures the rack management controller, which then automatically translates and distributes the power consumption limitation settings to all nodes in the rack, significantly reducing the time and complexity of the configuration process.
2Productivity
If the rack management controller automatically calculates and distributes power consumption thresholds to all nodes, then the operational efficiency improves significantly, but the system complexity increases
Solution Approach 1:
The rack management controller performs self-service by automatically calculating the power consumption thresholds for each node based on the total power consumption limitation value received from the user. The controller autonomously distributes these calculated thresholds to all nodes in the rack without requiring manual intervention, thereby improving productivity while managing system complexity through automation.
Solution Approach 2:
The rack management controller performs preliminary actions by pre-calculating the power consumption thresholds for all nodes before distribution. This preliminary calculation step allows the controller to prepare all necessary configuration data in advance, enabling efficient one-time distribution to all nodes and improving overall operational efficiency.
