The ‘guarantee’ is that you’ll get 20% savings with both SAN and NAS. Apparently if I LIE to my configuration and say ‘Eh, I don’t care about that’ I still get OMG devastatingly positive results of capacity utilization.

You look at the comments and it's a case of "There they go again."
Yet again the opposition can't put up nor can they shut up.
I knew the most virulent reaction to the guarantee would be from NetApp, their history of awful capacity utilization going back to the dawn of WAFL in the 90's (Nearly as old as FAT32 and unlike Wine file systems don't age very well) It was the same reaction when I pointed to the fact that with Celerra there is no degradation of NAS performance regardless of the protocol (CIFS or NFS) used.
At that time NetApp had to charge out and attack the benchmarks, highlight the fact that they've never submitted a CIFS benchmark and then used every excuse under the sun from their dog ate it to just wait and see what we'll do with PAM when the cards are created from 9th Dimensional Matter when asked why they've never submitted a CIFS benchmark.
In this case amongst all their hand waving the fact of the matter here is that EMC guarantees that for customer needs EMC Unified Storage requires 20% less raw capacity or it will match the shortfall.
That's it.
No pages of fine print. No RAID 10 on a Sunday before Mass. No need to bring your lawyer or promise not to covet your neighbors disk drives, sacrifice your first born to Cthulhu or any of the the other bloated arse covering legalese nonsense found in less efficient guarantees from less efficient vendors.
