my sales guy basically said the guarantee works as follows - they don't hit the 4:1 target, they buy you whatever amount of shelf\ssd required to makeup shortfall.  

The magic has to do with what they call "compaction" - writes <4KB (down to 512B/ea) are "compacted" into a single 4K block... this apparently adds to the std dedupe and compression they use.

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.
