Which bond mode do you use, out of curiousity? Not sure I would go to
this extreme, though; I would still want the physical isolation of
Management vs. network/VM traffic vs. storage, but just curious which
bonding mode?
Modes 1 and 5 would seem to be the best ones, as far as maximising
throughput. I read an article just the other day where a guy detailed
how he bonded four 1Gbit NICs in mode 1 (with each on a different VLAN)
and was able to achieve 320MB/s throughput to NFS storage.
As far as the storage question, I like to put other storage on the
network (smaller NAS devices, maybe SANs for other storage) and would
want the VMs to be bale to get at those. Being to use a NIC to carry VM
traffic for storage as well as for host access to storage would cut down
on the number of NICs I would need to have in each node.
