This is how we "solve" the bottleneck issue in our primary
implementation of GlusterFS : two physical networks, one for normal
traffic on eth0 (i.e. interaction with the web servers), and a second
for storage traffic on eth1. Furthermore, we use server-side AFR, thus
the clients never talk to each other (further reducing overhead).
