01 What happened
A Microsoft Tech Community blog published on October 14, 2026, describes implementing a 2+2 SAP HANA HA/DR topology on Azure using the SAPHanaSR-angi package. The configuration uses a two-node active cluster in the production region and a two-node passive cluster in the DR region, connected through asynchronous HSR. The DR cluster runs in DR mode (PREFER_SITE_TAKEOVER=DR) and never promotes a primary automatically; regional takeover is always a manual decision.
02 Key details
- Implements SUSE's technology preview scenario "Performance-optimized, multi-target SR, third site in passive cluster" using SAPHanaSR-angi only.
- DR cluster in DR mode: monitors SAP HANA, keeps IP resource stopped, never takes over automatically; regional takeover is manual.
- Prerequisites include async replication between regions, sync/syncmem within each cluster, identical SSFS keys; SUSE recommends disabling automatic cluster start.
- The blog is a working example from a test environment; official SUSE man pages are authoritative and must be consulted.
03 Why it matters
For SAP HANA on Azure customers requiring robust DR with local HA at the DR site, this pattern provides a tested configuration for a 2+2 topology. However, it is a SUSE technology preview with specific prerequisites and manual takeover steps, including potential data loss due to asynchronous replication.
04 Who it matters to
SAP HANA administrators, azure infrastructure architects and SAP Basis teams.
