Re: space reporting on AFF's with compression?

OK, no responses to my below so let me ask a simpler question.

The System Manager Dashboard's "Capacity" pane says I'm using 1.83PB 
with 11.7TB available. That's clearly not accurate.

If I click into the arrow in that pane I get the Tiers page and it says 
my two Tiers respectively have 875TB used and 6.5TB available, and 1PB 
used and 5.2TB available.

What the hell are these numbers describing?


Hope to hear from you
