With Nimble's compression, would there be much of a space savings with using Windows 2012's de-duplication feature on file servers?

Since the dedup is done at the windows level it wont make any difference if you use nimble or not.
however the advantage might be in the architecture.
if you have 100GB of data and windows is able to dedup that down to 50GB, you're IO requirements will be higher.
lets then say that nimble can get that down to 40GB.
you then end up with some really hard hit disks. because nimble uses the compression and SSD's you could get better performance out of it because you'll get better use of the SSD/caching technology.
From a Nimble perspective it's advisable not to use host-based de-dupe/compression if possible - reason being it could impact the array based compression and layout of the blocks on spindles as it runs it's processing on the volume (which in turn, could produce larger than required snapshots due to blocks being changed/moved).
It's a similar reason why we don't recommend running Windows Defrag.
Thanks for the information guys, it makes sense.
One additional question. Since we are perspective buyer is there access to the setup/admin guide to review prior to receiving the array and having an engineer onsite to set it up? I would be interested in reviewing the best practices and what have you, but it appears as though some resources are unavailable to those who are not a customer?
