Those sales folks may be misunderstanding the details. Ask to see the details of the guarantee, and read for yourself.
My experience with CDOT 8 on a AFF8020 was that video didn't compress/dedupe hardly at all (12% savings from dedupe, 0% from compression). Student home directories are getting about 48% savings (close to 2:1).
I imagine certain data stores will have much better savings (like lots of copies of VMs with identical OS images on them).
NetApp has a tool you can use to estimate savings of your own data, though it caps the size of the analysis at 2TB (regardless of the size of the volume being analyzed). They call it SSET (Space Savings Estimation Tool). I'm not sure whether that's specific to CDOT 8 or not.

Sales guys are promising me 4:1 dedup ratios on an AFF with ontap9. They say they grantee it. I have specifically asked what stipulation. In a VDI environment with linked clones, etc. Sales guy tells me none and even specifically says they can dedup compressed video or audio (mp3) 4:1.
I have A LOT of trouble believing that. So, 4:1 dedup guaranteed or what?
Any comments welcome.
