Re: NetApp should clarify the 4:1 claim

I think it's fantastic. Allows the customer to upgrade from 4:1 to 400:1 in a second by just thin provisioning more non-existant space.
Seriously, any vendor claim is legitimate if it documents exactly what ratio can be attributed to what reduction technology. Like Compression 2:1, dedupe 2:1 Thin provisioning:1.5:1 Overall 6:1
You may then get a quick figure for a given use case. Like database of unique png images, 20% thin provisioned: ratio = 1.2:1
I'm not sure Pure is much more transparent in that respect.
