Computer Node Power Supply Redistribution via BMC Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional computer server systems, the failure of a power supply module can cause a computer node to stop operating, leading to increased workload and instability for other nodes that must compensate, affecting the overall system's stability and efficiency.
Innovation Solution
A power supplying method where a baseboard management controller detects abnormal operation of a power supply unit in another computer node and controls the connected power supply unit to provide additional power support, ensuring continuous operation by redistributing power between nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If each power supply module only provides electric power to the corresponding computer node, then the system structure is simple and easy to manage, but the system reliability deteriorates when a power supply module fails
Solution Approach 1:
The patent merges the power supply functions by enabling power supply modules to serve multiple computer nodes. Specifically, a first power supply module can provide power to both a first computer node and a second computer node, creating an interconnected power distribution system where power resources are shared across nodes rather than being dedicated to single nodes.
Solution Approach 2:
The power supply modules are designed with multi-functionality to perform multiple roles. Each power supply module can function as a dedicated power source for its corresponding node while simultaneously serving as a backup power source for other nodes. This universal capability allows the same power supply module to adapt to different power delivery scenarios based on system needs.
2Reliability
If a power supply module fails, then the corresponding computer node stops operation, but implementing mutual power support increases device complexity
Solution Approach 1:
The baseboard management controller serves as an intermediary that manages and coordinates power distribution across the system. It monitors the operational status of power supply modules and automatically routes power from functioning modules to nodes experiencing power failures, thereby implementing complex power management functions through a centralized control mechanism that simplifies the overall system architecture.
Solution Approach 2:
The system establishes preliminary power support relationships before failures occur. By pre-configuring which power supply modules can support which computer nodes, the system prepares compensation pathways in advance. When a power failure occurs, the pre-established relationships enable immediate power redistribution without requiring complex real-time decision-making or system reconfiguration.
3Reliability
If one computer node fails due to power supply issues, then other nodes must compensate by increasing workload, but this reduces overall system efficiency
Solution Approach 1:
The power supply system implements self-service through automatic detection and response mechanisms. The baseboard management controller autonomously monitors power supply status and automatically activates compensation power supply from alternative modules when failures are detected. This self-service capability eliminates the need for manual intervention and ensures continuous operation without disrupting system productivity or requiring other nodes to artificially increase their workloads.

AI summary
A power supplying method for a computer system is proposed. The computer system includes a first computer node, a first power supply unit corresponding to the first computer node, a second computer node, a second power supply unit corresponding to the second computer node, and a connection module electrically connected to the computer nodes and the power supply units. The power supplying method includes: detecting, by the first computer node, whether the second power supply unit operates abnormally; and upon detecting at least that the second power supply unit operates abnormally, controlling, by the first computer node, the first power supply unit to provide electric power to the second computer node through the connection module.
