International Business Machines Corporation has successfully completed compatibility and interoperability testing of the IBM DS8880 products in IBM z Systems environment.
Please see the below attached qualification letter for a summary of the results.
GDPS 3.12 Enhancements
IBM GDPS V3.12 includes a number of new capabilities that address improved cross-platform support, enhanced availability, increased scalability, and simplified systems management.
GDPS PPRC z/OS Proxy
GDPS/PPRC can now support HyperSwap for systems that are not part of the GDPS sysplex. This capability, provided through use of the z/OS Proxy, a lightweight GDPS agent running on the systems outside the GDPS sysplex, enables more flexibility in the configuration of your overall GDPS environment and the capability to protect either stand-alone z/OS systems or other sysplex environments that may not otherwise warrant a full GDPS implementation.
GDPS Support for Multi Target PPRC
GDPS introduces a new product to support Multi-Target Metro Mirror on the IBM DS8870. Initial support is for two synchronous copies from a single primary volume, also known as a Multi-Target Metro Mirror (MTMM) configuration. GDPS/MTMM provides similar capabilities as those already available in GDPS/PPRC while extending PPRC management and HyperSwap capabilities to cover the two replication legs.
GDPS Virtual Appliance
The new IBM GDPS Virtual Appliance extends GDPS capabilities into z/VM and Linux on IBM z Systems environments that do not have z/OS in production. The GDPS Appliance is designed to provide a simple and easy-to-use GDPS platform through the use of a new and intuitive web interface for managing and controlling the environment.

GDPS 3.11 Enhancements
In Version 3.11, GDPS has been enhanced with a number of new capabilities that address improved cross-platform support, enhanced availability, increased scalability, and simplified systems management. In addition, GDPS can now support a four site configuration with the release of GDPS/Four Sites Symetrical Metro Global Mirror. This capability allows 4 copies of data to be managed by GDPS across sites in a production region and a disaster recovery region, provides the ability to switch between regions, and provides customers with both high availability and disaster recovery in both regions.

GDPS active-active continuous availability
GDPS active-active continuous availability (GDPS/A-A) is the next generation of GDPS and a fundamental paradigm shift for near continuous availability solutions. GDPS/A-A combines the best attributes of the existing suite of GDPS offerings and expands it to allow customers to achieve unlimited distances between their data center sites and achieve the recovery time objectives of 1 minute or less previously only available in a metro area solution.
GDPS/A-A is two or more sites, separated by unlimited distances, and having the same data, with cross-site workload monitoring and balancing. Full GDPS/A-A is planned to be delivered over time. The first configuration was the Active/Standby configuration which was made available in June 2011. GDPS/A-A has been enhanced and updated to include a new configuration called Active-Query. In addition to all of the function that the previously announced Active-Standby configuration provides, customers will now be able to use the IT capacity in their secondary sites for query (read only) transactions, thus exploiting a new workload balancing capability.
More information on GDPS / A-A can be found in announcement 613.033 .
