Venkat,

Can you give some more details about your setup and requirements?   
PVFS doesn't allow a single server to listen on multiple interfaces of  
the same type (in this case ethernet), but you could possibly run  
separate servers on the same node using the two different interfaces X  
and Y for each server (the storage spaces those servers manage would  
be separate as well).  It doesn't sound like that's what you want  
though.

Also, it probably wouldn't be hard to allow the PVFS TCP code to  
listen on multiple endpoints (nics) at the same time, if you were  
inclined to do some hacking.
