Configuring High Availability for Partitioned Regions
By default, VMware GemFire® stores only a single copy of your partitioned region data among the region’s data stores. You can configure VMware GemFire to maintain redundant copies of your partitioned region data for high availability.
With high availability, each member that hosts data for the partitioned region gets some primary copies and some redundant (secondary) copies.
Configure in-memory high availability for your partitioned region. Set other high-availability options, like redundancy zones and redundancy recovery strategies.
