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.
