Executive Overview 1 SAP creates enterprise software to manage business operations and customer relations. The company’s best known software products are its Business Suite of solutions (such as SRM, CRM, SCM, PLM and ERP), its Enterprise Data Warehouse solution (SAP Business Warehouse – SAP BW), SAP Business Objects, and the Sybase and HANA data platform. For further information on SAP products, see - product categories . The two key components of any SAP solution are the SAP NetWeaver and SAP Web Application Server. n SAP NetWeaver is the technical foundation for many SAP applications. It is a solution stack of SAP's technology products. n The SAP Web Application Server is the runtime environment for SAP applications on which all of the Business Suite solutions run. Production support for SAP NetWeaver and the Business Suite of SAP solutions on VMware vSphere has existed since 2008, and this support now includes SAP Business Objects and the Sybase and HANA database platform.

As a SAP customer you may be wondering how to realize the benefits of virtualization technology for your SAP environments. SAP and VMware have teamed up to offer a joint solution that helps speed your path to virtualization and reducing operating costs while minimizing business risks. For details on VMware offerings refer to http://www.vmware.com/products.html This chapter includes the following topics: n “Why This Guide ?,” on page 5 n “Target Audience,” on page 6 n “Understanding the Benefits of Virtualizing SAP Deployments with VMware,” on page 6 n “What do Customers Say About the VMware SAP Solution?,” on page 7 n “Overview of the VMware SAP Solution Guide,” on page 7 Why This Guide ? If yours is like most IT organizations today, you’re under constant pressure to do more with less – even as demand for your services continues to increase. You’re expected to drive down costs and operate at peak efficiency. You’re also expected to do this while enabling business innovation and supporting a global user base in a secure manner where people want to access enterprise resources on whatever device they choose. VMware, Inc. 5 SAP Solution Guide Typically, adding physical server space to meet this demand is no longer an option. This only increases hardware, operations, and maintenance costs – and the resulting complexity often impedes productivity and adversely impacts availability. This is why leading IT organizations and the businesses they serve are moving to virtualization technology to establish secure private cloud infrastructures. Virtualized private cloud infrastructure allows you to abstract physical server resources that you can pool and from which you can automatically provision services on demand. This enables you to maximize data center capacity and ensure the highest levels of availability. The result is greater business agility, improved scalability, and faster time-to-market advantages without the risk of turning over critical corporate data and security responsibilities to a third party. By using the right virtualization and management tools from SAP® and VMware, you can dramatically increase transparency in your SAP landscape and simplify SAP administration with a single pane of glass. This book provides you with the tools you need to understand the VMware virtualization infrastructure and management tools and how to use them in the context of your SAP landscape. Target Audience This document is primarily written for people familiar with SAP products but unfamiliar with VMware's infrastructure and management products, Software Defined Data Center (SDDC), and how to leverage said products to enable automated provisioning of and management of SAP systems. Understanding the Benefits of Virtualizing SAP Deployments with VMware Software defined data center (SDDC) refers to a data center where all infrastructure is virtualized and delivered as a service. Control of the data center is fully automated by software, meaning hardware configuration is maintained through intelligent software systems. This is in contrast to traditional data centers where the infrastructure is typically defined by hardware and devices. SDDC are considered as the next step in the evolution of virtualization and cloud computing. It provides a solution to support numerous enterprise applications like SAP and also other cloud computing services. Customers can transform and virtualize their entire SAP landscapes, from transactional to analytic workloads, and take the next step toward the Software Defined Data Center (SDDC). Running SAP on VMware platform provides the simplicity, efficiency and agility customers demand for their most mission critical enterprise environments. You get the following benefits by virtualizing SAP environments on VMware: n High Availability – VMware vSphere High Availability capabilities with automated fault tolerance enable SAP managers to deliver exceptional uptime and business continuity for their mission critical environments n Automated Provisioning - You can do on-demand deployment of applications in minutes with automated provisioning and template cloning. This ensures consistency and scalability across SAP environments n Live Migration of workloads - You can migrate live running workloads from one certified host to another with zero downtime and zero data loss with VMware vSphere vMotion n Reduce Capital and Operational Expenses - Your CapEx and OpEx expenditures reduce along with better utilization of existing infrastructure and resources along with automated provisioning and management. This enables to lower the Total Cost of Ownership (TCO) n Support Services - SAP and VMware have established a world class support infrastructure along with dedicated teams focused on customers. You are thus assured of dedicated and excellent customer support that is even more significant in the context of Business Critical Application (BCA) 6 VMware, Inc.
