We are running a 3-node cluster, with _direct_ 10G cable connections
(quasi crosslink) between the three hosts. This is very low-budget, as
it gives you 10G speed, without a (relatively) expensive 10G switch.

Working fine here, with each host having a double 10G intel nic, plus a
regular 1G interface.

Could you please send me details how you configured your network?
I am planning this configuration too, but didn't test it yet.
My special interest is how you prevented ethernet loops und what did you
changed on the default ceph settings?

Thanks a lot,
Björn Lässig
