Replication server configurations

A source replication server can replicate client node data to only one target replication server at a time. However, a single target replication server can be the target for multiple source replication servers. A client node cannot back up, archive, or migrate data to a server where the node is a target node for replication.

The example configuration in the following figure illustrates the relationships between source and target replication servers in a network.

The image and the elements of the image are explained in the topic text.

Figure 1 depicts the following data movements:

PHOENIX_SRV and DALLAS_SRV replicate client node data to each other. Each server is both a source and a target for replicated client-node data.
NODE1 and NODE2 are defined to PHOENIX_SRV. The nodes are configured for replication. During store operations, NODE1 and NODE2 send their data to PHOENIX_SRV. The data is then replicated to DALLAS_SRV.
NODE3 is defined to DALLAS_SRV. The node is configured for replication. During store operations, NODE3 sends its data to DALLAS_SRV. The data is then replicated to PHOENIX_SRV.
Data belonging to NODE4 and NODE5 is replicated to DALLAS_SRV.

Data that is replicated to a target server cannot be replicated again. For example, the data that belongs to NODE4 cannot be replicated to PHOENIX_SRV from DALLAS_SRV.
