through rigorous design rules, design walk-throughs, peer reviews,
element/subsystem/system simulation, and extensive engineering and manufacturing testing.
The z990 RAS strategy is focused on a recovery design that is necessary to mask errors and
make them “transparent” to customer operations. There is an extensive hardware recovery
design implemented to be able to detect and correct array faults. In cases where total
transparency cannot be achieved, the capability exists for the customer to restart the server
with the maximum possible capacity.
1.3.15 Software
By supporting the Application Framework for e-business and Linux on zSeries, IBM provides
organizations with the choices and flexibility needed to develop a robust infrastructure that
provides the end-to-end qualities of service, speed of innovation, and affordability required for
successful e-business.
It also enables a higher degree of integration among the three classes of workload—data
transaction applications, Web applications and special function applications—that are the
basis of providing a seamless business transaction over the Web (see Figure 1-6).
The result is an infrastructure that supports a more rapid move into advanced e-business,
and a better chance of recognizing a lasting competitive advantage.

Traditional database/transaction workloads
z/OS is well positioned as the deployment platform for e-business data transaction
workloads. The traditional S/390 strengths—scalability, high availability, low total cost of
ownership, and robust security—are all necessary elements for a company seeking to create
the kind of flexible computing infrastructure required for enterprise-wide e-business solutions.
In addition, batch workloads, which never go away, even in an e-business environment, are a
strength for z/OS, particularly with its ability to run concurrent batch jobs with online and Web
