There's not much you can do in this scenario to address the problems. NFS is session based, so there is no way to distribute the data across multiple links without using NFS version 4.1 and the session trunking feature. In that case, multiple sessions are established from the host and logically treated as a singular connection. If one session dies or the filer becomes unavailable, the remaining, surviving sessions are maintained (assuming they can be reached via your other switch).

I rarely go through this sort of effort. Most filers support the creation of a VIP and advertise their VIP MAC address on the link of their choice. If link 3 were to die, the filer would detect the failure and migrate its VIP MAC to the other switch. Normal MAC table updates would inform the host to use the other vmnic.

Hope it helps.
