HA was already given due consideration in the early development phase of Hana on IBM Power. As with Intel x86-based Hana systems, Suse also contributed its expertise from Hana development in terms of HA.<\/p>\n

One thing is clear: for data center managers or IT managers today, there is no question as to whether a system environment must have HA features or not. In times when SAP has to run virtually 24 hours a day, system failures always mean a standstill or non-availability of business-relevant or critical business processes.<\/p>

\"Fullsize\"<\/a><\/div>\n

SAP infrastructures must be designed to be HA-compliant, just in case. This applies to both classic SAP and SAP Hana-based solutions.<\/p>\n

With the operating system platform Suse Linux Enterprise Server (SLES) for SAP Applications for SAP Hana, IBM Power on Hana users now have a whole range of sophisticated functions at their fingertips to realize their Hana deployment as optimally as possible:<\/p>\n

for example, support for demand-based balancing for large in-memory workloads, ensuring high performance even in system stress situations (both in physical and virtualized systems), features or templates for rapid commissioning of SAP applications - or important features for business continuity or high-availability requirements through the built-in Suse Linux Enterprise High Availability Extension.<\/p>\n

Cluster reference architecture<\/h3>\n

The central anchor point for Hana-HA is the \"SAP NetWeaver High Availability Cluster 730 Certification\", presented by SAP in October 2012.<\/p>\n

This is the first time that SAP has specified a cluster reference architecture containing clustering guidelines that solution providers must fulfill. Incidentally, Suse was also involved in the development of this clustering architecture.<\/p>\n

SLES and Suse Linux Enterprise High Availability Extension fulfill the SAP Cluster 730 certification accordingly (de facto and from the outset).<\/p>\n

This is both a standard for SAP clustering solutions and a requirement that such HA solutions can be implemented easily, quickly and cost-effectively and can be used efficiently.<\/p>\n

Linux clustering technology elements from the Pacemaker open source project (for cluster resource management) have been incorporated here.<\/p>\n

Interestingly, an IBM developer, Alan Robertson, was significantly involved in the predecessor of Pacemaker called Heartbeat and even initiated Heartbeat.<\/p>\n

Anyone who now uses Hana on Power with Suse Linux Enterprise Server for SAP Applications, the recommended and preferred Hana operating system platform, is in a comfortable position when it comes to HA: namely to make two physical Hana servers highly available via clustering.<\/p>\n

Added value in a package<\/h3>\n

In addition, IBM's virtualization technology LPAR (Logical Partition or server partitioning) can be used on individual servers to achieve extended HA for both NetWeaver and Hana.<\/p>\n

Incidentally, SAP Classic and SAP Hana-based solutions can also be operated advantageously under SLES in a Power environment. With Power on Hana, IBM provides both extremely high performance for Hana - which SAP benchmarks have also shown - as well as extended HA features for business-critical SAP use.<\/p>\n

In combination with Suse SLES, this demonstrably results in an advantageous additional benefit or added value, even for future applications such as cloud computing, real-time analytics\/big data, Industry 4.0 or IoT.<\/p>\n
