Alternatively you might consider traffic shaping. DRBD can only set a
fixed limit (because it knows only about its own traffic). Traffic
shaping can adjust the limit depending on other traffic (it can also
prioritize traffic, etc.). However, to be effective, it needs to run on
a router as close to the bottleneck as possible - typically that means
either the border router or the firewall. So it is something the
customer's network guy should set up.
