Fan out IP pool failover allows Cluster A to replicate data to Cluster B and cluster C using IP pool failover mode.
Requirements
- Dedicated pools on all clusters, a pool on the central cluster can only replicate to one other cluster, it cannot be shared to replicate to 2 clusters.
- Cluster A pool A must be mapped to Cluster B Pool A (names of pools are examples only)
- Cluster A pool B must be mapped to Cluster C Pool B
Supported Configurations
- A single access zone on the central cluster can have pool A replicated to cluster A and pool B in the same access zone replicated to cluster C
- More than one access zone on central cluster can replicate an access zone to Cluster A or cluster B but must use dedicated pools for each replication relationship
