How to Configure High Availability and Clustering on Red Hat Server? Any Advice?

Hey everyone,

I am currently setting up high availability (HA) and clustering on a Red Hat Server and want to ensure a stable and efficient configuration. Since downtime can significantly impact business operations, I need a failover mechanism that minimizes service disruptions and ensures continuous availability.

From what I understand, Pacemaker and Corosync are commonly used for clustering in RHEL, but I’d like to confirm the best practices for deployment. When configuring a cluster on a Red Hat Server ( https://www.lenovo.com/de/... ), is a two-node setup sufficient for most workloads, or should I consider a multi-node cluster for added redundancy?

If anyone has experience with high availability on Red Hat Server, I’d love to hear your insights on best configurations, potential challenges.

Thanks in advance.
