I wouldn't know, but for that money I'd be expecting very high-performance and all the service trimmings.

That sounds a bit steep. I'm working on Dell Ceph configs at the moment, whilst I know we're getting decent discounts they aren't out of the ordinary for medium-large volumes - we're not even buying a PB up-front.
For a straight disk setup (4TB NL-SAS) on an Intel Ivy platform including PERC 710p we're looking at about ~AU0.30c per usable GB.
For a 1:2 (200GB DCS3700 SSD : 4TB NL-SAS) setup it's under ~AU0.60c.
And erasure coding is coming (so usable capacity goes up)!
