Solution Overview

Problem

Users face limitations in restoring critical software in information handling systems, leading to data loss and increased downtime, as existing recovery methods are often reactive and require technical support, failing to restore functionality effectively.

Innovation Solution

A management controller in the information handling system is configured to detect missing critical software through heartbeat synchronization signals and initiate the staging of restore images for installation, utilizing out-of-band management facilities to proactively restore critical software functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users uninstall critical software or re-image the information handling system, then the system can be customized or simplified, but critical health and performance monitoring functionality is lost

Engineering Contradiction:

Improvesystem customizationVSAvoidhealth and performance monitoring functionality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The management controller stores restore images of critical software components and automatically restores them when missing software is detected, preventing complete loss of monitoring functionality

Inventive Principle:

Principle #10Preliminary action

2Ease of repair

If existing recovery methods are used to restore critical software, then some software functionality can be recovered, but the methods are reactive and require technical support assistance

Engineering Contradiction:

Improvesoftware recovery capabilityVSAvoiddowntime and technical support requirements

Core Design Contradiction:

Ease of repairVSLoss of time

Solution Approach 1:

The management controller autonomously detects missing critical software through heartbeat signals and automatically initiates restoration without requiring user intervention or technical support

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses heartbeat synchronization signals from software services to continuously monitor the presence of critical software and triggers automatic restoration when absence is detected

Inventive Principle:

Principle #23Feedback

3Productivity

If critical software is not restored proactively, then the system can operate with reduced functionality, but data loss and downtime increase

Engineering Contradiction:

Improvesystem operation continuityVSAvoiddata loss

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

Restore images are pre-stored in the management controller, enabling immediate restoration without external downloads, thus minimizing downtime and preventing data loss

Inventive Principle:

Principle #10Preliminary action

AI summary

An information handling system may include a processor and a management controller electrically coupled to the processor and configured to provide out-of-band management facilities for management of the information handling system, the management controller further configured to in response to one or more heartbeat synchronization signals received from a software service of the information handling system, wherein each of the one or more heartbeat synchronization signals is associated with an item of software stored on the information handling system, determine if any critical software is missing from the information handling system, and for each item of missing critical software, cause a service operating system of the information handling system to stage installation of a restore image of such item.
