I checked; doesn't seem to be an issue:

# cat /etc/fstab
csddata7-vlan35:/vol/vol0/replica /replica             nfs 
proto=tcp,suid,rw,vers=3,proto=tcp,timeo=600,retrans=2,hard,fg,rsize=8192,wsize=8192 
0 0

I'd be interested in any feedback on the settings. The connection 
between server and NetApp is on a private vlan on a separate network 
interface than the rest of the LAN. I'm not positive, but I think we 
have jumbo frames (9K) enabled on that interface ... looks like we do:

# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:09:6B:E6:33:B7          [...]          UP BROADCAST RUNNING MULTICAST
MTU:9000 Metric:1
 

Thanks,
