Set Enforce Unique Host

Configure GemFire XD to use only unique physical machines for redundant copies of partitioned table data.

Understand how to set a member's gemfirexd.properties settings. See Configuration Properties.
Configure your members so GemFire XD always uses different physical machines for redundant copies of partitioned table data using the gemfire.properties setting enforce-unique-host. The default for this setting is false.
Example:
enforce-unique-host=true
