Technische Universität München enables cloud-ready SAP Business Suite 7 on IBM Power Systems


Published on

The Technische Universität München(TUM) in Germany implemented a fully cloud-enabled infrastructure based on the IBM Power Systems platform that automates many administration tasks and greatly accelerates preparation for the new semester. TUM can provision a new server in 30 minutes (a 90 percent reduction) and provision a new SAP instance in less than half a day. The University replaced 150 Sun servers with two IBM Power servers and two IBM BladeCenter systems, cutting 13 full racks to four half-racks, a saving of 85 percent, and cut energy usage by around 80 percent.
