Reduce downtime of critical operations.

SUSE Linux Enterprise for SAP Applications is a platform that includes high availability and security features to limit downtime of SAP landscapes including NetWeaver, SAP HANA and S/4HANA. It delivers the following built-in features to reduce downtime:

SUSE Linux Enterprise High Availability Extension
SUSE Linux Enterprise High Availability Extension (HA certified by SAP) provides an integrated clustering solution for physical and virtual Linux deployments, enabling the implementation of highly available Linux clusters and eliminating single points of failure. You have the flexibility to configure and deploy your choice of multiple HA/DR scenarios for SAP HANA and applications.

SAP HANA resource agents
Resource agents (SAPHana and SAPHanaTopology) enhance the SAP HANA system replications setup. This feature automates the takeover in SAP HANA system replication setups for scale up and scale out deployments, reducing data recovery time for large in-memory datasets from hours to minutes. As a result, they reduce the length and the number of interruptions when you use both your business-critical SAP systems and also your SAP HANA databases. Configuring the automated takeover is integrated with SUSE Linux Enterprise High Availability Extension.

Learn how you can ensure disaster tolerance of a SAP HANA System.

Full operating system rollback
The full system rollback feature of SUSE Linux Enterprise Server gives SAP customers better resiliency. It lets you take snapshots of the system, including the kernel files, and roll back as needed. Because the bootloader is now integrated into the rollback process, system administrators can boot from a snapshot, enhancing fault recovery and change tracking and comparison and improving data safety. When you upgrade to a new service pack for your SUSE Linux Enterprise Server, the full system rollback capability minimizes the risk and allows you to rollback easily.

Live patching
The live patching technology, delivered through SUSE Linux Enterprise Live Patching as a separately purchased extension to SUSE Linux Enterprise Server for SAP Applications, allows you to update the Linux kernel with security patches without rebooting machines or waiting for the next service window. Stopping the kernel is problematic for low-latency applications such as transactional databases. SUSE Linux Enterprise Live Patching doesn't stop the system during patching, so it reduces the lengthy downtime of recovering huge in-memory databases like SAP HANA.

SAP HANA Firewall
Secure SAP HANA in-memory systems with a built-in firewall that can be automatically configured, or easily set-up with a wizard.

Encryption management
Protect data in remote data centers with enhanced encryption management for dedicated storage volumes.

“Huge numbers of enterprises across many industries choose to run their SAP applications on SUSE Linux Enterprise Server because it provides a stable platform for business-critical systems. We have been running SUSE Linux Enterprise Server for two and a half years, and have not experienced any unplanned downtime.”
