This means, for example, ment that enhances the way customers set up, operate, and that companies can do more testing during an upgrade FlexFrame for SAP Solutions: A Brief History In 2001, the average SAP customer ran fewer than 10 SAP applications. However, as SAP broadened its portfolio, companies began to rely more heavily on these offerings for their business operations. We expected that this would increase the number of SAP applications running per customer. To preemptively support these customers, SAP, Network Appliance, and Fujitsu Siemens Computers established a joint development project. Through the project, SAP developed the Adaptive Computing Controller tool and Fujitsu Siemens Computers developed the FlexFrame solution. And now that predictions have come to fruition — with some data centers reporting that they run up to 100 SAP applications per customer — FlexFrame customers report that our solution enables them to run their systems with fewer resources than they would otherwise have been able to. In the meantime, VMware evolved to be a leading platform for server virtualization. Running SAP software on VMware’s virtualized platform allows customers to share one physical server among multiple virtual servers and thus multiple applications. FlexFrame supports these virtual servers with its capabilities to run heterogeneous server environ- ments. These capabilities also seamlessly support virtual servers — like those run by VMware — as separate models. w w w. S A P i n s i d e ro n l i n | Jan Feb Mar 2009 n n S-

PAN Manager Software by Egenera is an advanced management suite that aggregates servers into pools of processing resources — just as a storage area network (SAN) creates virtual pools of data storage. This approach provides IT administrators the flexibility to assign SAP components to servers based on processor and memory requirements, without having to worry about hardware or software configurations. PAN Manager automatically provisions servers with the appropriate software stacks, storage resources, and network identities. Additionally, PAN Manager’s processing pools can contain both physical and virtual servers, giving administrators the flexibility to manage a combined SAP infrastructure using a single set of tools. PAN Manager also enables applications to retain their bindings to network addresses and storage logi- cal units, regardless of which server hosts the application. S- Jan n Feb n Mar 2009 | w w w.

  • 14. s p e c i a l f e at u r e Virtualization | SAP InSIder Optimize Your Operating System With Para-Virtualization Traditional virtualization products relied on hardware emulation — intercepting and translating hardware requests from guest virtual machines. This approach creates significant overhead, especially for I/O-intensive workloads, and limits the scalability of the virtual environment. For these reasons, enterprise class workloads such as databases or ERP systems are seldom virtualized in production. Previous customer experience might tell us that any system that needs high performance or needs to be scaled is not a candidate for virtualization. After all, applications, such as those for financial trading, that require low latency or are time sensitive have often been unable to benefit from virtualization. Until now. In Red Hat Enterprise Linux 5, Red Hat optimized the OS to work in a virtualized environment, using para- virtualization to eliminate the I/O bottlenecks and remove the need for complete system emulation. Removing this overhead results in significantly better performance, especially for I/O-intensive workloads. Para-virtualization solves traditional virtualization challenges such as clock-skew — in which problems synchronizing the clock between the hy- red Hat is working pervisor and multiple virtual machines cause time to be “lost” as the guest clock runs more slowly than the host. closely with SAP Red Hat Virtualization also supports dynamic resource allocation, allowing memory and CPUs to be added or to ensure that removed from a live virtualized server.
