A single dual port gigabit card on each server.
I'm more concerned about performance than redundancy.
The bond operates in 2 gigabit mode:
ethtool bond1
(...)
Speed: 2000Mb/s
Duplex: Full
(...)
My working config (will play with it a bit more):
auto bond1
iface bond1 inet static
slaves ens1f0 ens1f1
address 192.168.200.1
netmask 255.255.255.252
bond_miimon 100
bond_mode balance-rr
bond_xmit_hash_policy layer3+4
I've done a simple some performance test - copied a file over ssh (which
adds own overhead).
90-100 MB/s over a single link and 150-160MB/s over a dual bond
So it's definitely working and making a substantial difference.
Unplugging one cable doesn't break the transfer; speed temporarily
decreases but then goes up again after cable is reinserted.

Are these "just" 10/100 cards? I mean, if they're gbit capable,
crossover cables violate the spec, and you're limiting them to 100m
