The GDPS Family An Introduction to Concepts and Facilities, SG24-6374 book provides information to help you understand the capabilities of the various GDPS offerings, and helps you identify the offering that most closely addresses your availability and disaster recovery requirements. It discusses both two-site and three-site scenarios, distributed over metro and global distances.
Now, the book has been updated with information about the latest release of the GDPS/Active-Active Sites offering, release 1.4. This release expands GDPS/Active-Active to provide the ability to run a read/write workload in one site, and a query workload in the other. It also adds support for replication of VSAM data. Additionally, support has been added for GDPS/Active-Active to coexist with the GDPS/PPRC or GDPS/MGM offerings, thereby providing a major step forward in enabling customers to create a configuration that delivers both disaster recovery and continuous availability over both metro and global distances.
For information about this significant enhancement to the GDPS family of offerings, refer to the latest edition of this book, available now at http://www.redbooks.ibm.com/abstracts/sg246374.html?Open.
