Well, in our case, we have two clustered switches from C-company so two
NICs in each. And then, yeah, different VLANs for every network on top of
the same bond. Works like a charm:)

Hello K,
coming back to the question, I have only 1 VLAN dedicated to Netapp NFS
infrastructure and I can't manage to add another.
Can I manage to use anyway 802.3ad on 4 adapters using any particular
option for this bonding mode at oVirt and switch side?
I think that at network side we have 4 x 3130 clustered Cisco switches so
in theory I can use this bonding mode.
I don't know if I can configure more than one IP on the same lan inside one
Netapp svm to configure more that one NFS share.
And if 802.3ad mode would assure to use 2 different network adapters when
pointing to 2 different ips on the same network for the shares
And I have to configure parameters for bonding in oVirt too, in case I have
to set any particular one..
Thanks again,
Gianluca

Y.
In my experience, they will use the same NIC. You need, at least, two
addresses in different subnets for 802.3ad to load balance between the
interfaces.

/K
P.S. The only thing I can say for sure is that proper load balancing
will occur with separate VLAN interfaces and addresses in different
subnets. That much I know, because that´s how we did it:)
Just using addresses in different subnets may work too, I just don´t
know. Please try and post your results:)
