Compaction in our testing can be good, really good...an additional 20% in many of our test data sets on top of everything else. (SSET diagnosis)
However, there are limitations on how you get data into AFF to get compaction...IE, you cant snapmirror it.
It must transfer, as far as we're told today, via a host/file based migration. Be thinking bout this when you consider an AFF migration. It must be done outside on ONTAP.
We have pushed to get this fixed via a scanner/etc that reads and relays out the file based structure. _________________________________Jeff MohlerTech Yahoo, Storage Architect, Principal(831)454-6712 YPAC Gold Member Twitter: @PrincipalYahoo CorpIM: Hipchat & Iris

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.
