Introduction 7
• A new major enhancement of service and support for Netfinity servers is the
Call Home remote support, using the latest technology advances delivered by
the IBM Netfinity 7000. Once available only in typical mainframe
environments, it is now available for an Intel processor-based server. If your
server experiences a problem, it will dial IBM to set in motion the right level of
support to keep your system up and running. In addition, you can select
options to have IBM contact you or your approved warranty service provider.
Using the multiple technologies in IBM's newest Netfinity server, Netfinity
Manager software and the Advanced Systems Management Adapter, this new
support capability allows it to remotely deliver hardware-problem
determination, launch on-site resources if needed and invoke any level of
support, including product engineering, within minutes. Included in this new
offering is a comprehensive problem-management system that provides
tracking, management, escalation and transfer of problem ownership to the
appropriate skills required to resolve an issue.
1.1.4 Implementation of High Availability
High availability means redundancy in all areas of a server system to make sure
the server is also available to the users in the case of hardware or software
failure. Netfinity Servers represent already a lot of high availability functions on
the hardware level. For more information about high availability on Netfinity
servers in the SAP R/3 area see 1.8, “High Availability” on page 12.
1.2 What is SAP R/3?
SAP is one of the largest software companies, providing integrated client/server
business solutions covering accounting, human resources, logistics and product
planning etc.
SAP stands for Systeme, Anwendungen and Produkte (Systems, Applications
and Products).
R/3 stands for Real-time system Version 3. Its predecessors, R/1 and R/2, were
real-time systems like R/3, but were available only on mainframes.
SAP R/3 is a very powerful modular application designed to integrate a
company's data. Everyone in a company can have access to the same data
stored in a common RDBMS.
SAP R/3 is a mission-critical business application that provides dynamic
information management for enterprises of all sizes of diverse industries.
The applications of the R/3 system are based on an overall business model that
makes possible a uniform view of all data and business processes in the
enterprise. The overall model covers the application areas shown in Figure 2.
