SCHWENK Zement builds its future with SAP applications, IBM DB2 and IBM System z


Published on

This white paper is an IBM case study. SCHWENK Zement migrated SAP NetWeaver Business Warehouse databases to IBM DB2 for z/OS on IBM System z , and deployed the SAP application landscape on VMware virtual servers on the IBM System x platform.At the same time, SCHWENK implemented IBM System Storage DS8100, IBM Metro Mirror for remote site data copy, with IBM System Storage TS3500 Tape Library for the long-term archive. The IBM Systems solution for SAP NetWeaver Business Warehouse Accelerator was also implemented.

Consolidate foundations or new build? Already with the upgrade from SAP R/2 to SAP R/3, options to migrate the SAP applications and databases to a new x86 server farm, or to consolidate all SAP databases to the IBM System z platform while reusing and virtualizing the existing Intel-architecture landscape as application servers were evaluated. SCHWENK already had positive experience of the reliability, availability and scalability of System z, which
