Introduction


SUSE Linux Enterprise + SAP HANA

SAP HANA was developed on SUSE

7,000+ SAP HANA customers on SUSE

SAP HANA Enterprise Cloud runs on SUSE

SAP IT runs SAP HANA on SUSE

17 out of 17 SAP HANA benchmarks on SUSE


SUSE Linux: Technology Leadership

SAP uses SUSE Linux as development platform for UNIX/LINUX

Co-developed Netweaver 7.30 Cluster certification

#1 provider for SAP HANA Scale-up HA/DR

Currently in Ramp-up for SAP HANA Scale-out HA/DR

20,000+ SAP customers rely on SUSE Linux


SAP HANA, our great simplifier for enterprise applicationsIncluding Carl’s non-official opinion on his journey to understanding!

Customer Success Story

Engage a single vendor for database and IT applications

Standardize IT server landscape to reduce cost and com plexity of its IT operations

Increase flexibility of its SAP ERP solution by migrating from Itanium -based servers to Industry-standard Intel Xeon servers

Geberit is a leading manufacturer of sani tary products, employing approximately 6,000 people worldwide. The company has 16 production facilities in Europe, China and the USA, and sells its products in 41 countries.

Infrastructure costs reduced by 50%

Performance improvements between 22% and 60%

72% reduced data volume

Integrated support between SAP and SUSE reduces administration effort

SUSE Linux Enterprise Server for SAP

SUSE Linux High Availability solution for SAP HANA

Migrated all SAP systems from Oracle to SAP HANA

Greenply Industries Ltd.

Spinoff of decorative business necessitated new SAP ERP Platform

Existing AIX/DB2 infrastructure too expensive and slow

Integrate supply chain with manufacturing to adjust production with demand in real-time

Greenply Industries is India’s largest interior infrastructure company with four state-of-the-art manufacturing facilities for plywood and MDF. Greenply has 45 branches across India and a distribution chain that spans more than 300 cities, 1,550 distributors and 10,000 retailers.

99.999% Availability for SAP Applications

SAP HANA license costs offset by cost-competitive infrastructure

Business users have real-time visibility into supply-chain and can leverage 8-10 years of historical dataFull backup takes 15 minutes compared to 10 hours

Scale-Up in a chain or multi tier - asyncron (->)A => B -> C

Scale-Up in a cost-optimized scenario (+)A => B + Q

Scale Up in a mixed scenario A => B -> C + Q

SUSE SAPHanaSR in 3 Facts

Reduces complexity- provides a wizard for easy configuration with just SID, instance number and IP address- automates the sr-takeover and IP failover ("bind")

Reduces risk- includes always a consistent picture of the SAP HANA topology- provides a choice for automatic registrations and site takeover preference

Increases reliability- provides short takeover times in special for table preload scenarios- includes the monitoring of the system replication status to increase data consistency


Outlook: HANA in a SUSE Linux Enterprise HA Extension ClusterHANA Multi Node – System Replication / Scale-OUT

SUSE is still scoping and researching this cluster concept.
