  What kinds of hardware are you using ? What is the Nas box, what
type of switch , and what are the Linux boxen? Can you send the list
the details and maybe the output from Lspci -lv and  pciconf -v would
be a good start.  Also can you confirm the nas has the correct
speed/duplex settings . This sounds like a network issue .  IMHO.
