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 introductory chapters of this publication are intended for a broad technical audience including IT System Architects, Availability Managers, Technical IT Managers, Operations Managers, Systems Programmers, and Disaster Recovery Planners. The subsequent chapters provide more technical details about the GDPS offerings and each can be read in isolation for those that are interested. Because of this, if you do read all the chapters, you may note that some information is repeated.
