This paper describes the approaches to optimize the management of an SAP system landscape. The central idea builds on the virtualization of the following layers: services (SAP application components), computing resources and a central storage device. This complements the undisputed virtualization technologies of PowerVM (e.g. micro-partitioning, virtual I/O, shared processor LPARs) of IBM, leading to increased flexibility and easier management of planned downtimes. One challenge in today's customer's IT environments is to avoid an increasing Total Cost of Ownership. That is why SAP developed a concept which has the central objective to start any service on any server at any time.
