No; I'm 100% its FD; HD gives 40k/sec TCP because of collisions and
such like.
Positive you are running at full duplex all the way to the
netapp, and if so how many switches sit between you and this
netapp?
It's FD all the way (we hardwire everything to 100-FD and never trust
auto-negotiate); I see no errors or such like anywhere.
There are ... <pause> ... 3 switches between four switches in
between, mostly linked via GE. I'm not sure if latency might be an
issue here, is it was critical I can imagine 10 km of glass might be
a problem but it's not _that_ far...
