With balance-rr you should reach 2000gbit as client is writing to 3
server simultaneously, thus, is using different
destinations/connections that are balanced.

You wont see the aggregated speed trying to communicate directly
between 2 hosts, but in this case, there are 4 hosts involved (1
"client", 3 servers) and thus 4 ips

Nope, communications with each server will be limited to 1Gbps max. Its 
just you will be able to write to each server *simultaneously* at 1Gbps.


Whats your network topology? servers are connected via a switch? what 
brand /model is the switch? does it have bonding setup?


Also whats the underlying disk setup - models, raid etc.
