To add to Matt's response:
From 11.1.0.7 onwards you can add the "dontroute" parameter to the oranfstab
file to allow the usage of multiple nics in the same subnet.
I have however not done any tests to see how well this works.
Also, in that case I think you can have a situation where the switch decides to
use the same outgoing port for all traffic, even if the source (incoming) port
is different.

If you could forward my response to the list, I'd appreciate it, as
somehow my posting to the list is broken.
The short answer is that they can be in the same VLAN, but different
*logical* networks, or different VLANs and different networks.
The longer answer is that you need something like
Nic0 - 10.1.1.5/24
Nic1 - 10.1.2.5/24
And on the filer:
Nic0 - 10.1.1.6/24
Nic1 - 10.1.2.6/24
You can have them on the same VLAN or different, it doesn't really
matter at this point. If they're on the same network, so, for example:
10.1.1.5/24 is nic0 and 10.1.1.4/24 is nic1, the box will not properly
load balance traffic between the two networks.
When you say traceroute, what does the output look like? If you're
expecting to get 10gb speeds, you really need to make sure that there
are no routers in between your filers/NAS heads and your database
machines.
