Remote Access Controller Failover via Telemetry Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In enterprise environments, systems with multiple applications and devices face challenges with remote access controllers (RACs) losing connections to networks frequently, leading to operational inefficiencies and potential failures.
Innovation Solution
A method is implemented to recommend changes to the RAC configuration by analyzing telemetry data to detect connection loss frequencies exceeding a threshold. The method involves determining the current RAC configuration and recommending modifications to how the RAC uses its network interfaces, which are then implemented.

1Reliability
If the RAC uses a single network interface for remote management, then the device complexity is reduced, but the reliability of network connection deteriorates due to frequent connection losses
Solution Approach 1:
The network interface functionality is segmented into multiple independent network interfaces (first and second NIs) within the RAC. Each interface can operate independently, and when one interface experiences connection loss, the system can switch to the other interface, thereby improving network connection reliability without significantly increasing overall device complexity
Solution Approach 2:
The system dynamically changes the operational parameters of the network interfaces by detecting connection loss frequency through telemetry analysis. When connection loss exceeds a threshold, the system modifies the configuration to enable failover capabilities, changing the state from single-interface operation to multi-interface redundant operation
2Reliability
If telemetry monitoring and automated recommendation systems are implemented, then the reliability of remote management is improved, but the device complexity increases
Solution Approach 1:
The system implements self-service through automated telemetry collection, analysis, and recommendation generation. The RAC automatically monitors its own network connection status, analyzes telemetry data to detect connection loss patterns, and generates configuration recommendations without requiring external intervention, thereby improving remote management reliability while keeping the operational complexity manageable
Solution Approach 2:
The system establishes a feedback loop where telemetry data from network interface operations is continuously collected and analyzed. This feedback mechanism detects connection loss frequency and triggers automated recommendation generation, creating a closed-loop system that continuously improves remote management reliability through data-driven configuration optimizations

AI summary
Embodiments described herein relate to a method for recommending changes to a system that includes a remote access controller (RAC) which has at least two network interfaces (NI). An orchestrator reconfigures the remote access controller and/or it network interfaces when telemetry is retrieved from the system and the telemetry indicates that the remote access controller loses its connections with a connected network at a greater frequency than a threshold. The orchestrator determines recommend changes, notifies a user, and when able reconfigures the remote access controller to at least use the at least two network interfaces in a failover configuration.
