Abstract
This IBM® Redbooks® publication presents an overview of the GDPS® family of offerings
and the role they play in delivering a business IT resilience solution.
This book begins with a discussion of general concepts of business IT resilience and disaster
recovery along with some issues related to high application availability, data integrity, and
performance. These topics are considered within the framework of government regulation,
increasing application and infrastructure complexity, and the competitive and rapidly changing
modern business environment.
Next, it describes the GDPS family of offerings with specific reference to how they can
achieve your defined goals for disaster recover and high availability. Also covered are the
features that simplify and enhance data replication activities, the prerequisites for
implementing each offering, and some hints for planning for the future as well as immediate
business requirements. Tables provide an easy-to-use summary and comparison of the
offerings, and the additional planning and implementation services available from IBM are
explained.
Finally, a number of practical customer scenarios and requirements are described, along with
the most suitable GDPS solution for each case.
The intended audience for this book includes Systems Programmers, Technical Support Managers, Operations Managers, Availability Managers, and Disaster Recovery Planners.
