Configure Redundancy Zones for Members

Group members into redundancy zones so GemFire will separate redundant data copies into different zones.

Understand how to set a member’s gemfire.properties settings. See Reference.

Group your partition region hosts into redundancy zones with the gemfire.properties setting redundancy-zone.

For example, if you had redundancy set to 1, so you have one primary and one secondary copy of each data entry, you could split primary and secondary data copies between two machine racks by defining one redundancy zone for each rack. To do this, you set this zone in the gemfire.properties for all members that run on one rack: pre redundancy-zone=rack1

You would set this zone gemfire.properties for all members on the other rack: pre redundancy-zone=rack2

Each secondary copy would be hosted on the rack opposite the rack where its primary copy is hosted.
