Broadcom DX Infrastructure Observability: High Availability Guide

Introduction to High Availability

This document provides essential information and step-by-step instructions for implementing High Availability (HA) for Broadcom's DX Infrastructure Observability (UIM) solution. High Availability ensures continuous operation and data integrity by setting up a secondary, or 'standby', hub that can take over if the primary hub becomes unavailable.

The guide covers the entire process, from understanding the core concepts of UIM High Availability and its use cases to detailed setup instructions, configuration options, and testing procedures. It also includes best practices to ensure a robust and reliable HA environment.

Key Topics Covered

• Understanding UIM High Availability concepts and use cases.
• Detailed HA hub installation options, including manual setup and using the UIM Server Installer.
• Configuration steps for the secondary (HA) hub, including probe management and essential settings.
• Procedures for testing HA failover and fallback scenarios.
• Troubleshooting common issues and recommended best practices for maintaining HA.

Environment and Prerequisites

The document outlines the specific environment and software versions required for a successful HA implementation, including details on UIM, Hub, Robot, HA probe, NAS, and Infrastructure Manager versions. It also specifies operating system and database requirements.
