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. Visit http://on.fb.me/LT4gdu to 'Like' the official Facebook page of IBM India Smarter Computing.
