Cannot find "Site Collection Storage Management" in SharePoint Online 2013

Our Microsoft TAM has told us of a recently deployed feature in SPO that allows all sites to shared a single pool of automatically managed storage. However the section of the admin panel he is telling me to use (named above) does not appear for me at all. This MS blog post also explains how to turn this feature on. The section highlighted simply is not there in my admin panel. I asked him for more information and here is his response (exact quote, except for the delinkifying the urls):

Enable self service http: http://ift.tt/1uSO42K and http: office.com/teachers will add an additional 750TB of pooled SharePoint Online storage.

I am thinking he skipped a couple of indefinite articles in that sentence. He seems to be telling me to permission my farm to allow users to create their own sites (which I already do), then go to two sites (both of which redirect to the same SPO login page), and then my 750TB will automagically appear. I have spent the last hour crawling through all the Site Features, Site Collection Features, and anything else I could think of. I still cannot figure out what he is telling me.

Coming to this community in hopes of avoiding humiliating myself front of my TAM. Please save me from this terrible fate.
