You can do this using server-side replication. You can use the bonded interfaces
for the connections between the servers.

However, there are two problems with this kind of setup:

1) Since your clients will not have replication on their side and will only connect
to one server, you will not have high availability. If the server that a client has
connected to fails, the client will no longer have access to storage. You'll have to setup
some other kind of failover to handle this.

2) Server-side replicate is not one of the officially supported configurations, and
is not as well-tested as the others.
