GDPS overview
Chapter 32.
Today's on demand data centers must be resilient enough to handle planned and unplanned
system outages without impacting the business of the enterprise.
Most solutions that help provide continuous IT service availability are based on cluster server
software, mirrored storage, and redundant networks. When a failure occurs, an integrated
disaster recovery solution will, in a predetermined fashion, execute a set of tasks to restart
the operating system, recover storage servers and networks, and restart applications on a
different set of servers and storage in another location. This level of functionality is also
defined as
GDPS or Geographically Dispersed Parallel Sysplex is such a full function solution and
provides various levels of IT continuous availability through different implementation levels.
GDPS as a continuous availability and near-transparent disaster recovery solution is based
on Parallel Sysplex server functionality and disk mirroring utilizing Metro Mirror and Global
Mirror.
This chapter provides an overview of the various features that GDPS offers. More information
is available in IBM System Storage Business Continuity Solutions Guide, SG24-6547 and
