High availability in SAP HANA is often discussed as a single capability, but technically, it is not.
This article provides a consolidated, SAP-documented view of SAP HANA high-availability mechanisms, explaining how Host Auto-Failover, System Replication, topology choices, and cluster-based coordination interact and where their explicit technical boundaries lie.
Based strictly on official SAP documentation, the article clarifies what SAP HANA high availability is designed to achieve, what it deliberately does not cover, and why realistic availability expectations require architectural combinations rather than individual features. It enables precise, technically sound discussions around availability design, failure coverage, and the clear separation between HA, recovery, and disaster recovery.
