Endress+Hauser deploys one of Germany’s Largest Linux on the Mainframe Solutions Company consolidates global SAP system onto IBM z 990 using 36 Linux-Mainframe. Processors n Endress+Hauser has consolidated its SAP platform to run a central server solution at their n n facility in Weil am Rhein, Germany. This new installation offers Endress+Hauser improved availability, even higher security and greater productivity of its SAP systems. In order to further improve cost efficiency, Endress+Hauser has migrated its existing SAP R/3 systems from a Unix platform to Linux on the z. Series mainframe. By consolidating the production SAP systems onto one server platform, the company’s SAP system is easier to manage than ever before. The SAP systems are currently supporting 3, 500 users around the world and this number is expected to grow. The IBM z 990 supports 19 production SAP systems, which are distributed on 14 logical partitions. The related SAP databases, based on IBM DB 2, are distributed on 6 logical partitions. u. Source: IBM and Endress+Hauser press release, 11 th August 2004 n Competition – HP competed, and Dell Servers were displaced “Our key criteria in choosing the platform were to ensure the highest application availability as well as drive down costs.
