It works the same way as the deduplication on Celerra / VNX – just pull the white paper or manual for that from Powerlink – its got more technical info. The VNXe deduplication is less configurable but the underlying workings are the same.  Within one file system No limit on fs size ISCSI LUNs are not deduplicated
Hi  I would like to get some more knowledge about how the deduplication works on the VNXe.  in the white paper VNXe series a detailed review, there is a little bit of information on this, but this does not go very deep.  This is what is in the white paper     So can anyone point me in the direction of some more technical document that references this...  Some of the things we have we need answers to would be.  Will dedup work across file systems.( if you have 2 identical files but on different shared folders will that get dedupped) at what CPU utilization level does Dedup stop. and when does it start again. are there limits on the size of filesystems ( CIFS and/ or NFS) for using Dedup How much Performance will the Dedup use. Does the perfomance grow with the size of the filesystems How does Dedup work with snaps and clones How does Dedup work with remote replication are there any best practices for using dedup with Vmware og HyperV.  The white paper states that Dedup will work on whole files,and give saving of up to 50 % i thought that Dedup replaced the files with pointers to the original file....  And so on....  Thanks
