At our shop we have used quadstor - http://www.quadstor.com with good
amount of success. But our use is specifically for vmware environments
over a SAN. However it is possible (i have tried this a couple of
times) to use the quadstor virtual disks as a local block device,
format it with ext4 or btrfs etc. and get the benefits of
deduplication, compression etc. Yes btrfs deduplication is possible
:-), i have tried it.
You might need to check on the memory requirements for NAS/local
filesystems. We use 8 GB in our SAN box and so far things are fine.
