[gpfsug-discuss] GPFS de duplication

[Andrew Beattie]

Dave,

Spectrum Scale does not support de-duplication, it does support compression. 
You can however use block storage that supports over subscription / thin provisioning / deduplication for data only NSD’s, we do not recommend them for metadata.

In your scenario is user B planning on making changes to the data which is why you need a copy? 

I know of customers that do this regularly with block storage such as the IBM Flashsystem product family In conjunction with IBM Spectrum Copy Data Management.  But I don’t believe CDM supports file based storage.

The scenario would be user A creates a file or folder and user B takes a copy within the same filesystem, though separate independent filesets.  The intention would be to store 1 copy.    So I was wondering ....
