IBM GDPS
GDPS is IBM's solution to manage availability in z/OS environments, with extensions into Open and Linux solutions as well. Among other things, GDPS will manage the operational aspects of synchronous and asynchronous copy services solutions, such that you can ensure that in an event of disaster, all the proper actions will be taken.
The picture shows GDPS with PPRC, but GDPS can also be used with Global Mirror and XRC. GDPS supports IBM, HDS and EMC Disk Subsystems. GDPS supports a wide range of configuration options, and can be used to complete redundant environments, with both duplicate processors and duplicate I/O subsystems, such that many different kind of failures can be tolerated without downtime.
IBM has a section of their web site dedicated to GDPS
A good tutorial can be found in the redbook (currently in draft status)
GDPS Family - An Introduction to Concepts and Capabilities
IntelliMagic provides a White Paper on GDPS XRC.
In our products
IntelliMagic Vision provides all the required support to plan copy services implementations with GDPS, be it synchronous (PPRC/Metro Mirror), asynchronous (Global Mirror) or zSeries Global Mirror (XRC). RMF Magic supports EMC, HDS and IBM Disk Subsystems.
For XRC installations you can use IntelliMagic Vision to determine the bandwidth and throughput for individual readers even during the planning phase with the GEOXPARM command file. RMF Magic can use this file while you are developing it show you how much bandwidth will be handled by each SDM and reader. Once GDPS XRC is in production, IntelliMagic Vision can also monitor the response time on both yur primary and secondary configuration, including the journals.
