How to calculate Provisioned, Used Storage - considering DeDuplication, and Thin Provisioning in-use

CHIRAV — Thu, 05 Jun 2025 06:05:21 GMT

Have thin-provisioning, DeDuplication in-use.

We are looking to calculate an easier way, or provide some level of excel sheet to understand/show:

Provisioned space, Actual In-Use/used space, DeDuplication effect/savings (and how much would the required space be, if need to re-hydrate) etc.

Sure we can run df, df -s among other df options, and other tools -- but wouldn't there be an easier way to look and understand these aspect ?

We do not have DFM, probably not planning to implement either.

Insight Balance -- to be implemented at a later date.

So - trying to gather this information thru CLI, or thru System Manager, or Synergy etc.

Thx

Hi,

If you are looking for some kind of summary, why not use Storage Efficiency and Storage Efficiency 2.0 Beta tools on My AutoSupport web portal?

Sri,

you answered the question yourself, you need to use df ,df -s etc. output and calculate it yourself. Maybe the ONTAP SDK can be of help to you to create a nice script.

Besides that "aggr show_space -h" might provide additional data for you to integrate if you dont know that command already.

Godspeed,

Thomas
