Re: usable space

The NetApp Fusion* tool is telling me ~65.02 TiB usable.   

(*note: Fusion is for Partners and NetApp personal)  


To manually calulate it  you'll need to understand stand the way that ADP is configured on the disks. 

Read more about root-data and root-data-data here: https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-concepts%2FGUID-B745CFA8-2C4C-47F1-A984-B95D3EBCAAB4.html 


 With this base config, you would end up with 4 total aggrs.  2 root aggrs and 2 data aggrs.     

Each disk will have 3 total paritions.  1 root and 2 data.    root partition is ~53.88 GiB  each data parition is ~1.72 TiB.
