What kind of Deduplication rate are you seeing with the Data Deduplication Role?

I was wondering what kind of deduplication rates people were seeing in Server 2012 with the Data Deduplication Role enabled.

 

I'm seeing volumes with dedup rates of 78%, 79%, and 86% which are mainly saved Hyper-V clients, testing databases, and BDBB's I'm saving

I'm sure there's impact but on my S2012 storage server it's running on a N40L and I have Server Backup running at night plus one running Hyper-V client at the moment -- I'm not seeing the impact but I'm sure it's there.

You can run the DDPEval.exe tool

 

"When the deduplication feature is installed, the DDPEval.exe tool is automatically installed to the \Windows\System32\ directory."

 

Running this from the command line will give you an idea of how much space you can save. You can also run it against a variety of storage types which gets even more interesting.

 

I'll have to run it in a bit and post my numbers.
