Celerra NX-4 is gateway NAS?

Hi All,

Whether Celerra NX-4 is an integrated NAS or gateway NAS?

We have Celerra NX-4. Backend is clariion AX4-5F8. We are managing back end array through Navisphere manager and managing NAS part through unisphere. So, Celerra NX-4 falls on which type?

and also please suggest how do we differentiate gateway and integrated NAS systems?
