I think you are misunderstanding Mladen's comment. Of course the SA's have to label the disks and present them to the O/S. But thereafter the DBA can manage the available space without having to bring in people that, all too often, have no interest in understanding Oracle and the needs of the DBA team.

My opinion is that for almost everything Oracle ... ASM is the way to go.
