So they'll automagically realise they're supposed to use the second  
ethernet interface to talk to the SAN? Cos they're all connected  
together through the primary interface to the other (public, rest of  
the department) switch as well - how do they know the difference? The  
private network won't have DHCP so I have to set interface addresses.

Nothing under my control - our whole subnet is VLAN'ed by the  
university networks folks, but I can't see it having an effect.
