Quick Sizer Determining Your Sizing Requirements with Quick Sizer Business-Oriented, Proven, Cost-Effective Sizing Introduction Quick Sizer translates business require­ ments into technical requirements. It deploys a proven sizing methodology developed in close cooperation with SAP technology partners. By determin­ ing your sizing requirements, you can ensure that your hardware purchase will meet your business and perfor­ ance m requirements. A financial benefit will be lower costs and a reduced total cost of ownership. Just consider the costs of unused hard­ are – beyond its initial w price, you also have to account for the ongoing energy and mainte­ ance costs n it will accrue. An Economically Balanced System Sizing is brought to your desktop via an online application. Quick Sizer provides up-to-date sizing information and guides you through a structured questionnaire. The business requirements are stated as simple business-oriented figures such as the number of users or expected number of processed business process­ es and documents. These figures are translated by Quick Sizer into hardwareindependent requirements that enable initial budget planning. Based on the determined categories, SAP technology partners can propose a complete system configuration for your system landscape and components. The performance requirements of SAP® solutions are usually defined by the busi­ ness requirements. Hardware and sys­ tem performance, however, is measured by technical performance indicators. Matching these funda­ en­ ally different m t performance figures is the goal of the sizing process (see the following figure). To this end, the information provided by Quick Sizer can help you select the hardware and system platform needed to meet your business requirements.

For small busi­ ess­ s, n e the user-based sizing approach might be appropriate. Business requirements are determined by the number of users performing specific business tasks. Users are grouped per business task according to their estimated usage activ­ ity. Based on this information, a rough sizing recommendation is provided. For midsize, large, and complex businesses, an additional throughput-based sizing is recommended. Besides the number of users, additional information about the number of business processes and business objects is used. The sizing methodology is based on performance measurements and is validated by approximately 50,000 SAP projects created per year. Over 14,000 customers have successfully sized their hardware with Quick Sizer since July 2005.2 The Result: A Balanced Set of Needed Hardware Components SAP’s comprehensive sizing methodol­ ogy helps ensure that all the needed hardware components build a balanced system infrastructure. Database and application servers are adequately equipped to fulfill the business require­ ments. The right combination of process­ ing performance (in SAPS),1 amount of disk space (in MB), disk I/O, and main memory (in MB) is proposed. Cooperation with SAP Technology Partners Comprehensive sizing support is a joint effort – SAP has developed and deployed the sizing methodology in close cooperation with its technology partners. Unified standards and goals agreed upon by SAP and its technology partners help ensure the right match of hardware technology and business.
