Abstract:

 

In today's always-on digital economy, ensuring the high availability of SAP landscapes is critical for business continuity. This session explores a robust and enterprise-proven high availability (HA) architecture for SAP ASCS and SAP HANA databases running on SUSE Linux Enterprise Server (SLES) 15 SP3 using the open-source Pacemaker cluster framework.

Attendees will gain deep insights into how Pacemaker and Corosync work together to deliver fault-tolerant SAP services, including automatic failover, STONITH fencing, and resource monitoring. The presentation will cover system architecture, deployment components, and integration with SAP-specific agents, along with a discussion of real-world benefits such as reduced downtime, increased resilience, and cost efficiency. Whether you're planning a new S/4HANA deployment or modernizing an existing landscape, this session provides practical guidance for building a resilient SAP environment aligned with SAP and SUSE best practices.
