GDPS is designed to work with Metro Mirror (PPRC), z/OS Global Mirror (XRC), or Global Mirror disk replication protocols.

Some disk features require specific commands that need to be sent to the disk subsystem. A matrix showing what is required for which features can be found in:
International Business Machines Corporation and Hitachi, Ltd. have successfully completed compatibility and interoperability testing of Hitachi products in IBM System z environments.
GDPS Qualified DWDM Vendors
These vendor products have been tested and qualified by IBM using the same laboratories and procedures used to test all aspects of a GDPS environment. This testing includes functionality, recovery, and in some cases performance measurements. Vendor products qualified for Server Time Protocol (STP) are also included.
