Are ISV Partner applications that are certified for SUSE Linux Enterprise Server also considered certified for SUSE Linux Enterprise Server for SAP Applications?

Yes, since SUSE Linux Enterprise Server and SUSE Linux Enterprise Server for SAP Applications of the same version and service pack are the same underlying system, third party applications that are certified on SUSE Linux Enterprise Server should function the same on SUSE Linux Enterprise Server for SAP Applications.

What problem does the Page Cache Limit feature solve?

Many SAP applications are designed to use large amounts of memory for optimal performance. The Linux kernel pages out rarely-accessed memory for filesystem performance. These optimizations conflict causing SAP application performance to slow down, and if the application is built on Java the “garbage collection” process makes it even worse. SUSE has developed the Page Cache Limit exclusively for SUSE Linux Enterprise Server for SAP Applications to give you control of page caching. You can set a limit to the memory that will be paged out, and therefore maintain SAP application performance. These limits are in effect as long as RAM is available in the system. For details go to www.suse.com/documentation/sles_for_sap/sles_for_sap_guide/data/cha_s4s_configure.html.

How does SUSE Linux Enterprise Server for SAP Applications help in the transition to S/4HANA?

SAP’s strategy for S/4HANA is to simplify how its products are deployed and consumed. Part of this strategy to support Linux as the sole OS. IT staff who are familiar with UNIX for their SAP environments will not have a difficult time learning how to work with Linux. However, users of Microsoft Windows Server will find Linux to be very different and becoming comfortable with it will be more challenging.

To help these administrators become productive more quickly, SUSE Linux Enterprise Server for SAP Applications provides support for the Microsoft Remote Desktop Protocol. This working environment combined with a guide for administrators to perform common Windows Server tasks with SUSE Linux Enterprise Server will ease the transition to running S/4HANA environments on Linux.

SUSE Linux Enterprise Server for SAP Applications also includes Enhanced Active Directory Integration to support existing Microsoft user IDs and passwords to save time and effort with transitioning security to the new environment.

IT organizations who need assistance with migrating their SAP NetWeaver and SAP HANA environments to S/4HANA can find tools and services from partners participating in the SUSE Connect Program.
