Ontap 8.3.2RC2 and AFF8080 - Vols created by default with 'space-guarantee=none'

Hi all,

I'm still pretty new to Cluster Data Ontap and have the following doubt:

 

We have a cluster containing AFF8080 and FAS8040 nodes, and noticed by default the volumes created on its aggregates aren't using the same space-guarantee.

On SSD-based aggregates the volumes created are set as "none". While for SAS-based it is set as "volume"

 

Would be possible to set by default "space-guarantee=volume" also for SSD-based aggregates?
Or has it anything to do with the storage efficiency policies running by default on AFF systems?

I know the benefits about thin provisioning but we'd like to preallocate space in advance

 

Thanks in advance for your help

Best regards,

Daniel
