Even the storage servers themselves should access GlusterFS content via a Gluster or NFS mount. Anything else will cause corruption of metadata (at least), and quite possible the Gluster volume.

What you are saying is that it is not a good idea to access the data directly even in the case of a single storage server when no glusterfs client is running on that server.
