After extensive market evaluation, FOITT selected IBM® Power10 servers as the strategic platform for SAP S/4HANA operations. The combination of resiliency, availability, performance and virtualization capabilities showed that IBM Power10 would enable FOITT to consolidate to just five servers, dramatically reducing cost and complexity. Further, the simplified systems architecture would enable FOITT to introduce extensive automation, improve resilience and help optimize resource utilization, all of which would deliver increased efficiency.
The Federal Administration embarked on a transformation program and named it SUPERB—short for Support, Processes, ERP and Bund (the German word for “federal”). Working closely with UMB and the IBM Technology Lifecycle Services team to implement the infrastructure and for support during the hyper-care phase, FOITT is progressively migrating its SAP solutions to IBM Power® servers, running the SUSE Linux® Enterprise Server operating system. Each IBM Power server runs multiple virtual servers, using IBM logical partition (LPAR) virtualization, which enables processor and memory capacity to be allocated optimally to SAP S/4HANA applications, maximizing utilization.
Bruno Willener, Solution Architect Hardware/OS at FOITT, reports: “On x86 servers the memory and processor sizing is less flexible, which often resulted in significant over-investment. IBM Power10 allows us to allocate memory and processor capacity in increments of one-hundredth of a core.”
In terms of SAP solution performance, Ingo Berghahn, Solution Architect SAP Basis, adds, “The LPAR virtualization technology ensures that each SAP S/4HANA application is optimized for performance and that we maximize system utilization for the best possible return on investment.”
The combination of system scalability and virtualization has greatly improved service delivery, too, as Berghahn explains: “In addition, whereas the previous x86 systems could only be adjusted during downtime, with restarts taking around four hours, LPARs can be resized during production. The standard deployment at FOITT consists of three LPARs, for the application, central instance and SAP HANA database. For business-critical SAP S/4HANA solutions, we implemented production, disaster recovery and backup systems at three separate data centers, to ensure maximum resilience.”
Patrik Riesen, SUPERB Program Leader, comments: “By using IBM Power servers for our new SAP Basis infrastructure in the SUBERB program, we were able to achieve a very high degree of automation, which minimizes manual work and increases the efficiency of our IT processes. This makes it possible to provide new virtual servers for a complex SAP landscape with the SAP HANA database in an automated and standardized manner within just a few hours.”
This capability has also transformed the FOITT’s service portal that enables users to specify and order new SAP S/4HANA systems. When a confirmed request arrives, FOITT uses automation to set up the required LPAR and SAP S/4HANA instance and database, and provide them within an hour. With IBM Power, FOITT is able to offer enhanced service to the Federal Administration, while reducing administration, accelerating delivery and cutting costs.
