Hi,
Yes, it is our undertanding that if the hardware (switch) supports it,
"bond-xmit-hash-policy layer3+4" gives you best spread.
But it will still give you 4 'lanes' of 1GB. Ceph will connect using
different ports, ip's etc, en each connection should use a different
lane, so altogether, you should see a network throughput that
(theoretically) could be as high as 4GB.
That is how we understand it.
You can also try something on the switch, like we did on our ProCurve:
Procurve chassis(config)# show trunk
Load Balancing Method: L3-based (default)
Port | Name Type | Group Type
---- + -------------------------------- --------- + ------ --------
D1 | Link to prn004 - 1 10GbE-T | Trk1 LACP
D2 | Link to prn004 - 2 10GbE-T | Trk1 LACP
D3 | Link to prn005 - 1 10GbE-T | Trk2 LACP
D4 | Link to prn005 - 2 10GbE-T | Trk2 LACP
Namely: change the load balancing method to:
Procurve chassis(config)# trunk-load-balance L4
So the load balance is now based on Layer4 instead of L3.
Besides these details, I think what you are doing should work nicely.

If using standard 802.3ad (LACP) you will always get only the performance of a
single link between one host and another.
Using "bond-xmit-hash-policy layer3+4" might get you a better performance but
is not standard LACP.

So what bond mode I suppose to use in order to get more speed? I mean how
to join the nic to get 4 GB? I will use Ceph!
I know I should use 10gb but I dont have it right now.
Thanks

No, not really. One connection is limited to 1GB. If you start more
parallel connections you can gain more speed.
