With an increasing number of customers either deploying or planning to deploy SAP Hana and Hana-based applications like S/4, BW/4 and C/4, cluster solutions (especially Hana-Linux clusters) are gaining importance mostly due to high availability as well as disaster and recovery concerns.
While some remain skeptical of SAP clusters or cluster solutions in general because of their supposed complexity, many successful operating SAP clusters prove that these doubts are unfounded. Concerning performance and ease of use, today’s SAP cluster solutions with suitable clustering software are way more advanced than they were ten or fifteen years ago.
SAP and partners like Suse support many different available cluster types, like performance optimized, cost optimized, or campus and geo clustering, which benefit from continuous improvements and have already been successfully deployed worldwide.
Hana-Linux cluster recipe books
Not every clustering solution provider offers ideal implementation support, and even fewer offer beneficial advice for seamless mission-critical cluster operation. Especially SAP users are often on their own – which is why Suse has been offering best clustering practices free of charge for over a decade. For example, the company offers material on setting up an SAP Hana SR cost-optimized infrastructure, setting up a high availability cluster for AWS or Azure, and setting up a simplified Hana system replication.
These best practices can be seen as kind of recipe books to build up or bolster know-how about clusters in the SAP ecosystem. The materials are continually improved and updated.
Furthermore, Suse’s best practices also include the implementation and use of various open source solutions, for example using YaST Wizzard in combination with Suse SLES for SAP Applications High Availability Extension, which is based on the open source clustering solution Pacemaker.
IT has always been complex, but complexity should be manageable – and often is, if companies know how. Suse has always believed that mission-critical SAP operations do not have to be complicated, and that information as well as automation are key to reducing complexity.
