[Users] deduplication

[Theron Conrey]

Hi Jose,

Deduplication or dedup for short is usually a function of the storage appliance, and as such is a "post-allocation" operation.  As a quick example the hypervisor will request the space, allocate all of it, and if space can be reclaimed via a storage side operation like dedup, that's where it's handled.  

If you're leveraging oVirt with storage appliance that supports dedup it will work just fine with oVirt as well.  

We DO however support thin provisioning.  This is a "pre-allocation" operation handled by oVirt.  Instead of just waiting on the storage to reclaim space via a dedup job (if this isn't done inline dedup can be taxing on the storage array and is usually a scheduled job that isn't constant) thin provisioning only allocates the storage space that is actually required.
