This blog post was written by the following team of technical professionals: Juliet Candee, Jiong Fan, Paulo Shimizu, Sidney Varoni Jr and Shu Xie. The team met at IBM in Poughkeepsie, NY to write the IBM Redbooks publication GDPS/Active-Active Overview and Planning, SG24-8241 which will be available in draft at the IBM Redbooks website very soon.
GDPS Active/Active is a solution designed to provide near-continuous availability and disaster recovery readiness for mission-critical applications, running workloads in two data center sites separated by unlimited distances. Here are 5 things you should know about GDPS Active/Active:
GDPS/Active-Active solution is designed to provide continuous availability for critical business application. At the same time, the system resources and near real time production data available on the alternate site can be leveraged for workload balancing and data analytic workloads.
Supports virtual unlimited distances for asynchronous data replication by using IBM software replication products. GDPS/Active-Active solution causes almost no impact to production workload by using software data replication technology.
Is an integral part of GDPS/A-A solution which performs load balancing of workloads. It monitors site and workload health, distributes workloads between the sites, switching to an alternate site in planned and unplanned events.
GDPS/A-A manages and controls replication in the application level and relies on software-based replication techniques to synchronize data between sites. It currently supports DB2, IMS and VSAM workloads, and also provides integration support with GDPS/MGM and co-operation support with GDPS/PPRC.
GDPS/A-A is the latest GDPS-family product. It detects conditions and provides control for activities required in both planned and unplanned events, in application level of granularity. Allows site switch of seconds after an event is detected and also RPO of seconds, protecting against metro and regional disasters with minimal response time impact.
