SAP with Microsoft SQL Server 2005: Best Practices for High Availability, Maximum Performance, and Scalability6
This section describes typical reference architectures that are capable of supporting small-scale, midsized, and the largest, most demanding SAP implementations. The architectures show the basic elements that can be used in a variety of implementation scenarios. This section also provides an example implementation of Microsoft Information Technology (IT) SAP with SQL Server 2005.
In practice, each SAP implementation must be adapted and designed jointly with a SAP-certified hardware vendor to address the customer’s unique requirements. These might be, for example, preexisting infrastructures, business models, or business impact assessments.
Each of the mySAP with SQL Server 2005 reference architectures meets the following requirements:
High availability. The architectures are designed for high availability to provide the best performance and to ensure fault tolerance.
Scalability. Additional servers can be added quickly and easily without disrupting the existing site, thereby enabling SAP installations to rapidly increase the number of concurrent users.
Support for large volumes of data. The application and database configuration can grow from hundreds of gigabytes to multiterabyte databases.
In most SAP implementations, customers install mySAP and SQL Server 2005 Enterprise Edition with the assistance of a SAP-certified partner. Microsoft-certified partners with SAP-certified consultants are available to support the installation of SQL Server 2005.
The SAP with SQL Server 2005 reference architectures are designed to use commodity servers and storage that is available from leading hardware vendors. This reduces the TCO and ensures that maintenance and support costs can be well-managed.
