The GDPS family of System z Business Continuity solutions consists of two major offering
categories, and each category has several subofferings. Each GDPS solution is delivered
through IBM Global Services, and is specifically tailored to fit a specific set of client recovery
needs, budgetary requirements, physical distance and infrastructure, and other factors.
The three major categories of GDPS solutions are:
GDPS/PPRC solutions, based on Metro Mirror. Metro Mirror was formerly known as
Peer-to-Peer Remote Copy (PPRC).
GDPS/XRC solutions, based on z/OS Global Mirror. z/OS Global Mirror was formerly
known as Extended Remote Copy (XRC).
GDPS/GM (Global Mirror) solutions, based on Global Mirror.
The subofferings within these three GDPS major categories include the following:
GDPS/PPRC

– GDPS/PPRC HyperSwap Manager, a Tier 6 solution
– RCMF/PPRC, a remote copy management solution for PPRC
GDPS/XRC
