i have nearly the same setup:
- Ubuntu 14.04.
- 4 nodes (relplicate distributed)
- bricks are on lvm on a mdadm raid 10
used bonding (802.3ad/bond-mode 4) before but did not see real benefit
in speed for vms. depending on what you do 1 gb might be already enough.
nevertheless we bought 10 ge hardware now
For the vms i recommend to use libgfapi which will have better
performance and the load of your gluster nodes will go down:
I also used these hints:
Whats also important:
