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.
