[Beowulf] cheap 48 port gigabit ethernet switch w/ jumbo frames?

[Tom Rockwell]

Hi,

I'm looking for a switch that will be used for NFS traffic on a cluster 
of about 40 nodes.  The nodes will have Broadcom 5704 ethernet.  From 
what I've read, jumbo frames is important for getting the best NFS 
performance over gigabit ethernet.

D-link and Netgear have newer 48 port switches priced below managed 
switches.  The D-link is model DGS-1248T 
http://dlink.com/products/?sec=2&pid=367 and the Netgear is model GS748T 
http://netgear.com/products/details/GS748T.php.  Each are about $1200 or 
so.  I'm unable to find info on their websites specifying whether these 
switches support jumbo frames.  Anyone know?

Thanks,
