Hi Ronny,
Do you know if it's possible to have the 2 "real nodes" holding all the
data connected directly with a 2 x 1 Gbps bond and the third "dummy"
quorum member (tiny VM) accessible via standard LAN interface, i.e.
traffic going through LAN switches and VMware bond?
My 2 servers have 4 Ethernet ports each so it seams to make sense.
Sync data between them faster without clogging up the LAN.
Or purchasing a new switch for them to share and introducing a single
point of failure.

if you want synchronized data replication 1Gbps is going to be a royal
pain anyway. the latency will make everything slow.
so you must either look at async replication. Or look at improving the
cluster network.
I have used 10Gbps "mesh" networks between hosts before. But with the
low cost of 10Gbps switches nowadays it is pointless complexity.
dac cables + one of these, is my goto for cheap clusters now.

for redundancy if you can not do proper mclag switches you can look at
