Hana 2.0 Now Only With SLES For SAP Applications

Hana 2.0 will bring a whole range of further developments or modifications, also with regard to the use as well as the support matrix of Suse Linux Enterprise Server for SAP applications.

Hana 2.0 does not mark a historical departure in the sense that Hana 1.0 will shortly become redundant. But sooner or later the 2.0 version will come to represent a kind of standard.

SAP customers’ sights are primarily focused on Hana, or rather on the use of Hana as platform, for example on new features or additional functions connected with Hana 2.0 and provided by SAP. It’s safe to say that many of these, indeed very many will impact the following areas: database management, data management, analytical intelligence or application development.

For those in charge of SAP operations, enhancements as regards high database availability will likely be of particular interest, especially the Hana 2.0 feature “Active/Active (read enabled)” with the possibility of read data access on secondary systems in a cluster.

At the same time, using an active/active concept provides improvements in load balancing and performance.

Hana means Linux

Since Hana always requires the use of Linux, or as IDC once put it in a white paper: “Hana means Linux“, it is important to note that in Hana 2.0 there are also changes regarding the use of Suse Linux Enterprise Server (SLES). Moreover, the latest Hana version also has a modified, or a shortened support matrix.

As we already now, SLES is the most frequently used Linux operating system platform in the SAP environment, not least because right from the start Suse Linux Enterprise Server (including the High Availability Extension) was explicitly developed to meet the mission critical demands of SAP solutions (including enterprise support), or was steadily developed with this aim in mind, and that always in close consultation with SAP.

According to that leaner support matrix, in the future, three minor releases will be supported. SLES for SAP applications is the designated choice for Linux.

This applies to SAP classic with AnyDBs as well as to Hana or Hana-based solutions such as S/4.Up to the present it has been possible – with Hana 1.0 – to use two SLES variants, namely SLES Priority, the “normal” SLES, and SLES for SAP applications.

With Hana 2.0 from now on only  SLES for SAP applications is used. The reason: an optimized and packaged product lifecycle management that keeps pace, so to speak, with a leaner support matrix from SAP for Hana.

According to that leaner support matrix, in the future, three minor releases will be supported. SLES for SAP applications is the designated choice for Linux. Incidentally, further information on this is provided in the corresponding SAP Notes (e.g. Note 2235581) that also describes which version of Hana-for-SAP-applications and which version of SLES-for-SAP-applications applies for Intel- and IBM-Power8-Hana systems.

Clear additional benefits

Of course, Suse for SAP customers with SLES for SAP applications as opposed to SLES Priority has several additional benefits or advantageous functions, for example, Suse HA/DR for scale-out and scale-up, integrated Suse support via SAP SolMan, basis for the use of live patching when using SAP, utilization of Suse tuning packages, Suse Connect access and much more.

But of overriding importance is the fact that, in contrast to “normal” SLES, with SLES for SAP applications an Extended Service Pack Support is available. This means that Service Pack support is extended from six to 18 months, a clear benefit for SAP customers.

    Hi Friedrich

    I read carefully SAP Note 2235581 you mentioned in your article. May I ask where you have found a statement, that only “SLES for SAP” is allowed to use in HANA 2.0?

    This note says about two supported Linux distributions, RHEL, and SLES, and both are supported in their both flavours (with or without “for SAP”).

    Regards

      Because SAP Notes are changed quite frequently, I read SAP Note 2235581 version 27 dated 23.10.2017

    Hi Krzysztof, thank you very much for your comment on this. At august 2017, when the article was created, published in september 2017, SLES for SAP Applications was the only SUSE operatingsystem defined for HANA 2.0 in this sap note. In the meanwhile the SAP Note changed and HANA 2.0 is open for SLES from SUSE also. The optimized platform from SUSE for SAP HANA 2.0 is still the SLES for SAP Applications. rgds Fred
