I think that the possibility to add a separate storage network is a 
must. It doesn't make sense Gluster support if you can't separate 
management network traffic of storage network traffic. In 3.5 you can 
define management/vm/display/migration interfaces but not storage 
interfaces.  Why? I don't know. But I think that Gluster support is 
incomplete without exclusive storage networking.
