Cloud Tiering first shows you the estimated space that you can save on each cluster. 31 days after you discover the cluster, it shows you a precise value, if you’re running ONTAP 9.4 or later.

The initial savings opportunity that Cloud Tiering displays is an estimate based on industry standards. We estimate that 70% of the data on the cluster is cold data that you can move to lower-cost object storage.

Cloud Tiering displays an estimate because a 31-day cooling period is needed to determine which data is considered inactive. For ONTAP 9.4 and later, Cloud Tiering replaces the estimate with a precise value after this 31-day cooling period.

Here’s an example of an estimate showing 8.7 TB of capacity savings:

A screenshot that shows a cluster with an estimated space savings of 10.5 TB.

Here’s an example of a precise value for a different cluster that has not been set up for tiering:

A screenshot that shows a cluster with a space savings of 1 TB.

And here’s an example of a precise value on a cluster that is tiering some of it’s volumes, but not all:

A screenshot that shows a cluster with an additional space savings of 2 TB.
