Looking at the systems we had in production, we realized that, as a result of this oversight, they had been sending all outbound traffic via their fast ethernet interfaces rather than gig! Aaargh!
I want to correct what I wrote there; according to p. 561 of the ONTAP 5.3 System Administrator's Guide,
"The filer always responds to an NFS request by sending its reply on the interface on which the request was received."
Therefore, because all of our NFS calls were using the gig link, the responses were using the same, and the situation wasn't as bad as we first suspected. Even so, the configuration was not what we intended, so I'm glad our testing discovered our mistake.
On another note, Steve Vawter wrote to mention single-mode trunks for automatic failover between links on a single filer; that is, indeed, the subject of my current testing, but initially we simply wanted to have the onboard link on a different address in case of flakiness while configuring the GigE card (which we had encountered on our old F230). In fact, we've had no such problems with the 700 series.
