Replication on each link in a replication topology occurs between two separate HCP systems, each of which is complete in its own right. Because replication is a software function, the two systems can have entirely different hardware configurations, including differing amounts of storage.
The two systems in a replicated pair are connected through the front-end network infrastructure, as shown in the following figure. Replication traffic from each system must be routable to the network selected for replication on the other system.
Replication is a network bandwidth-intensive process. To ensure sufficient front-end network capacity when replicating, you must give extra consideration to planning the front-end infrastructure.
