Hi Radek,
Thanks for chimming in
If I may, I would like to contribute with some answers of my own to your questions...
Regarding your NFS question, We've still to hear back from Vaughn about my last querie:

When you mention failover partner are you referring to the other node and it's capability to assume the failed node identity?
Or, are you refering to some internal mechanism of Ontap that allows a surviving NIC (even without VIF configuration) to assume the IP of the downed interface (i.e the IP of e0 is assured by e1)
Kindest regards,
Now, if we assume that Ontap indeed does not transport the failed IP to the surviving NIC on the FAS, then we're left with no choice but to have etherchannel and/or have 4 NIC's on each FAS controller.
As you know, In VMWARE NFS terms you really can't connect more than one time to the same NFS export/IP combo per Host.
So, if you need to multi-path from the vSphere, you would connect to a different "IP/NFS export" in order to maximize your paths (i.e 2 NIC's on the vSphere host). Off course, we could go higher with IP alias.
Example:
Export A -- IP X on e0
Export B -- IP Y on e1
Therefore, since we have no failover of the IP itself (i.e no VIF), if a NIC fails on the Netapp you would effectively loose connectivity to the failed "IP/NFS export".
Example:
IP X -- Fails
We're left only with "IP Y" and therefore, the NFS "Export A" assigned to "IP X" becomes inacessible.
Hope this makes sense.
Cheers
