GDPS is a Disaster Recovery manager. It is a service offering supplied by IBM, rather than a software product. GDPS runs as a Netview application, making full use of SA390. It monitors all the LPARs in the Sysplex, both OSs and Coupling Facilities, it also monitors the DASD whether PPRC or XRC is being used to mirror the data.

HyperSwap allows a GDSP manager to move functions on demand.
