If you talk to the server people, they have an issue with this:
Latency.
I've talked to people who have collapsed layers in their LAN because they
can see performance degradation for each additional switch packets have to
pass in their NFS-mount. Yes, higher speeds means lower serialisation
delay, but there is still a lookup time involved and 10GE is
substantionally more expensive than GE.
