This IBM® Redbooks publication presents an overview of the IBM Geographically Dispersed Parallel Sysplex™ (IBM GDPS®) family of offerings and the role they play in delivering a business IT resilience solution.
The book begins with a discussion of general concepts of business IT resilience and disaster recovery, along with 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 hints for planning for the future and immediate business requirements. Tables provide easy-to-use summaries and comparisons of the offerings, and the additional planning and implementation services available from IBM are explained.
Finally, a number of practical client 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, System 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 who are interested. Because of this, if you do read all the chapters, be aware that some information is repeated.
