Within nine months, a total of 63 SAP systems were migrated to the new high-capacity servers (Integrity Superdome Server). Thereby, applications with a capacity of 270,000 SAPS were read into the new server platform. The unit SAPS (SAP Application Performance Standard) measures the capacity of SAP applications, irrespective of hardware and comparable to the PS of a motor. In this respect, the 48 server units resembled a car manufacturer’s selection of different models, whilst today four identical high-capacity, top of the range models are available. In order to secure the system, the project team put into operation – simultaneously to the productive servers – four additional high-capacity servers in a parallel data centre.
Technical and logistical challenges
Especially the migration of four systems presented the team of 40 with huge challenges, all of which were mastered successfully and on time. With the transfer of the BASF Group’s Business Warehouse (BW) system, a data amount totalling seven terabytes had to be read from the old servers and read into the new ones within a timeframe of only 48 hours. Seven terabytes represent around 11,000 CD-ROMs or seven billion printed DIN-A4 pages.
A particularly difficult task technically was also the migration of the APO system (Advanced Planner and Optimizer). With this SAP software for Supply Chain Management, the planning-relevant data is not, as with other applications, saved in databanks but held in a so-called ‘Live Cache’, where access is quicker. Hence, before the migration, the data had to be transferred in an additional step, into a regular databank.
Also the transfer of the Y 130 system, with which the BASF Logistic Center steers stock movement and transportation had to be carried out quickly. The project team had exactly 24 hours for the data migration, whilst the lorries were already waiting to start rolling again. The fourth major challenge was the migration of the logistic system Logibas, which with its approximately 5,500 users, has the highest number of users within the BASF Group. After the decision had been taken that the Logibas transfer would be carried out as a joint venture together with the Unicode migration, both were finalised in just one weekend.
“Especially the excellent cooperation and communication between HP and BASF IT Services, in our opinion, contributed considerably to the success of the project. As strategic partners, we complement each other perfectly with our respective know-how, so that we can offer our customers individually tailor-made solutions,” defines Dieter Fenchel, Project Manager HP Services Consulting & Integration, the rewarding teamwork between the partners.
Infrastructure simplified, software standardised, costs reduced
Through the migration to the new HP high-capacity server, the infrastructure could be simplified and the software standardised. Now everything is conform, the hardware via the operating system and SAP kernel through to the databanks. Also all the release versions of these components are now in alignment.
“It was very important for us, that during each phase of the migration, the user of the affected application could continue to work without interruption. Thanks to the good organisation of the project team, this worked out really well. All 63 systems are now running smoothly on the new platform. For us, the huge benefit of the new server is that through the standardisation, in the future we can react to changes and upgrades, much easier and quicker,” says Frank Peter, responsible for SAP Technology at BASF.
“The new, standardised server landscape guarantees more capacity and better quality. At the same time, we have for our customer with the successful migration, created the basis for potential cost savings in the future. Of course we offer our know-how in this area also available to companies in other sectors,” says Wolfgang Erny, Managing Director of BASF IT Services.
