Hardware Component Diagnostic Testing Without Disruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Server consolidation leads to increased hardware failure rates, where entire servers must be replaced or repaired when a component fails, even if other components remain operational, impacting system reliability and availability.
Innovation Solution
A method and system for performing diagnostic tests on hardware components without disrupting the operation of other components, involving a hardware management device that migrates agent devices and ensures no agent device is using the component during the test, allowing for extensive diagnostic testing while maintaining system functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If server consolidation is implemented to improve resource utilization, then resource efficiency improves, but hardware failure rate increases
Solution Approach 1:
The system segments the server into independent hardware components that can be individually tested and maintained. Each hardware component can be isolated and subjected to diagnostic tests without affecting other components, allowing continuous operation of the consolidated server while improving reliability through targeted component-level management.
2Reliability
If entire server is replaced or repaired when a component fails, then system reliability is restored, but resource availability decreases
Solution Approach 1:
The problematic hardware component is extracted or isolated from the server system for targeted diagnostic testing and replacement. This allows the failed component to be removed and replaced without affecting the rest of the server, maintaining resource availability while restoring system reliability through selective component-level maintenance rather than whole-server replacement.
3Measurement precision
If diagnostic test is performed on hardware component, then measurement precision improves, but system operation is disrupted
Solution Approach 1:
The diagnostic testing is applied locally to specific hardware components rather than the entire server system. The system implements component-level isolation where individual hardware components can be tested with high measurement precision while other components continue to operate normally, maintaining both diagnostic accuracy and system productivity through localized testing procedures.
