BMC Switch Circuit for Sensor Data Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information processing systems with multiple system boards, when a BMC on one board fails, the system struggles to acquire sensor data from non-Home SBs, leading to potential system errors and operational disruptions, as existing methods require suspending operations to replace hardware and restore BMC functionality.
Innovation Solution
The system implements a switch mechanism where a BMC on another board can take over the role of the Home BMC, allowing continuous hardware management and monitoring without stopping operations by using switch circuits to reroute signal connections and acquire information from hardware on failed boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a BMC on one board fails, then hardware management and monitoring are disrupted, but suspending operations to replace hardware causes operational disruptions and loss of time
Solution Approach 1:
The system performs preliminary actions by pre-configuring switch circuits and establishing alternative control paths before a BMC failure occurs. When a BMC fails, the switch circuits are already in place to immediately reroute control signals and sensor data flows, eliminating the need to suspend operations for hardware replacement.
Solution Approach 2:
The patent introduces switch circuits as intermediary components that mediate between the hardware and the control system. These switch circuits enable seamless redirection of control paths when a BMC fails, allowing another BMC to take over without operational disruption.
2Speed
If device switching is performed without control information takeover, then switching speed is improved, but control information loss occurs
Solution Approach 1:
The system performs preliminary actions by pre-configuring switch circuits and establishing alternative control paths before a BMC failure occurs. When a BMC fails, the switch circuits are already in place to immediately reroute control signals and sensor data flows, eliminating the need to suspend operations for hardware replacement.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors BMC status and automatically triggers switch circuit reconfiguration when a failure is detected. This feedback loop ensures that control information is preserved and transferred seamlessly, maintaining both switching speed and information integrity.
