SUSE: The Smart Choice for SAP


The year 2025 might seem far away today, unless you’re back from “Blade Runner 2049” or you’re in enterprise IT. In those cases, it’s just around the corner. That’s when SAP will end mainstream support for its traditional enterprise resource planning solutions and move solely to SAP S/4HANA, the platform that integrates core and cloud-based SAP applications for a true hybrid solution. It all runs on Linux-based HANA, SAP’s in-memory database that, in effect, supercharges your SAP applications with the power to process massive amounts of data in near real time.

Unfortunately, enterprises don’t turn on a dime, and the looming deadline is likely causing some angst among even the most seasoned IT professionals.

SAP’s decision to use only applications based on SAP S/4HANA after 2025 is a monumental shift, certainly. But here’s the good news: Migration can be a lot easier than you might think. Choosing SUSE® as the underlying operating system for SAP S/4HANA can smooth the transition and set up your IT and business for even greater agility and efficiency in the future.

Consider this: SUSE Linux Enterprise Server for SAP Applications is the recommended and supported OS of choice for SAP HANA and is currently running in 7,000-plus SAP HANA installations. Even more convincing is the fact that SAP itself uses SUSE Linux Enterprise Server for SAP Applications for its production and development environment.

Some people think Linux is Linux is Linux, but that’s not true.1 SUSE’s Linux OS is optimized for SAP applications and comes with very unique features that help reduce downtime, optimize performance and increase agility. These include:

High availability with automated failover. SUSE and SAP continually work together to improve the scalability and high availability of SAP HANA so you can include multiple nodes for system replication and application failover across multiple geographic locations. Built-in business continuity features include a full High Availability/Disaster Recovery solution with a GUI to easily configure physical and virtual system clusters; resource agents that automate the takeover in SAP HANA system replication setups; and full operating system rollback. There’s even an option to apply security patches to the Linux kernel without taking down your SAP systems for maintenance. We call it live patching, and only SUSE does it.

OS security hardening. The security of your underlying OS is just as important as the security of your database, because hackers often target the OS and not the database directly. SUSE has a history of focusing on IT security, including an aggressive international security certification program and an integrated antivirus solution for SAP environments. You also get a built-in firewall with automated configuration to secure SAP HANA’s in-memory systems.

Simple deployment and management. SUSE’s Installation Wizard automates the installation of SAP NetWeaver and SAP HANA solution stacks, including the high-availability stack, all optimized for the best performance. And SUSE Manager makes it easy to deploy, manage and configure all SAP systems from a single console.

Unparalleled performance. SUSE Linux Enterprise Server for SAP Applications consistently provides outstanding uptime and performance—even under full CPU loads and high memory stress. The Page Cache Management feature maintains high performance by allowing you to limit the amount of page cache used and free up memory for SAP systems to crunch data.

If you want to keep your SAP systems past 2025, you’ll have to run SAP HANA—and Linux. Make the smart choice and choose a Linux OS that is reliable, fast and secure. That’s SUSE Linux.
