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.
It begins with a discussion of general concepts of business IT resilience, the disaster recovery tiers defined by SHARE, and 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 management 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.
