Peripheral Device Shutdown Control During Host System Crashes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data processing systems face issues such as abrupt shutdowns during host failures, leading to data corruption, system instability, hardware degradation, and disruption of connected systems, due to the abrupt termination of processes and services.
Innovation Solution
A management controller is installed within the data processing system to manage peripheral devices independently, allowing for graceful shutdowns by determining if peripheral devices have their own operating systems and maintaining power until they complete their shutdown processes, thereby preventing abrupt power cuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the host system crashes and processes are abruptly terminated, then the system can recover quickly, but peripheral devices experience abrupt power cuts causing data corruption and hardware degradation
Solution Approach 1:
The patent segments the power management function by introducing a separate management controller that operates independently from the host system. This controller specifically manages peripheral device power states, allowing it to coordinate shutdowns without being affected by host system crashes. The segmentation enables reliable peripheral shutdowns even when the host system fails, preventing abrupt power cuts while maintaining system recovery capability.
Solution Approach 2:
The management controller performs preliminary actions by detecting host system crash conditions and proactively initiating graceful shutdown sequences for peripheral devices before actual power failure occurs. The controller monitors host system state and triggers shutdown protocols in advance, ensuring peripheral devices can complete their shutdown processes without abrupt power cuts, thus preventing data corruption and hardware degradation.
2Reliability
If peripheral devices are shut down gracefully, then data loss and hardware damage are prevented, but the shutdown process takes longer
Solution Approach 1:
The management controller implements feedback mechanisms to monitor peripheral device shutdown progress and host system state in real-time. Based on this feedback, the controller dynamically adjusts shutdown timing and power delivery to ensure graceful shutdown completion while minimizing overall duration. The feedback loop allows the system to optimize the balance between data integrity preservation and shutdown speed.
Solution Approach 2:
The management controller acts as an intermediary between the host system and peripheral devices during shutdown transitions. It mediates the power delivery and shutdown coordination, ensuring that peripheral devices receive controlled power during their shutdown sequences. This intermediary role enables graceful shutdowns that prevent data loss while managing the time required for proper shutdown completion.
3Reliability
If the management controller maintains power to peripheral devices during host failure, then graceful shutdowns can complete, but power consumption increases
Solution Approach 1:
The management controller dynamically adjusts power delivery to peripheral devices based on real-time system state and shutdown progress. During host failure conditions, the controller maintains power only as long as necessary for graceful shutdown completion, then reduces or cuts power once shutdown is confirmed complete. This dynamic power management balances peripheral device operation continuity with energy consumption, preventing unnecessary power usage while ensuring reliable shutdowns.
Data Source
AI summary
Methods and systems for managing a peripheral device of a data processing system are disclosed. When a data processing system crashes, all hardware components of the data processing system including any connected peripheral devices are abruptly shut down as a result of the crash. These components may still be running vital processes that could become corrupted as a result of the abrupt shutdown. These components may also be damaged physically as a result of the abrupt shutdown. A management controller may be provided to gracefully shutdown these components when the data processing system experiences a crash, specifically during a crash of a system host of the data processing system.
