Hello, Is that kind of functionality supported to tier ONTAP S3 bucket to ONTAP S3 bucket? Or how can we setup tiering for ONTAP S3?

There is no built-in tiering feature in ONTAP S3. There is FabricPool which tiers old blocks in aggregates but I'm not sure if using ONTAP S3 on a FabricPool-enabled aggr is supported.

#

You could use SnapMirror S3 to create copies of your objects to another S3 target (which can be another ONTAP S3).

The frontend protocol isn't really part of the calculation, afaik. A cold block gets tiered according to tiering-policies. If you can do it with aggregates with SAN volumes, I can't see why there should be restrictions on client protocols like S3, and I don't see anything in the docs saying it's not supported.
Whether it's a good idea or not, depends on the situation. There are definitely other approaches.

FabricPool won't work with ONTAP S3 FlexGroups. SnapMirror S3 is the way to go in this case

I don't interpret the table this way and snapmirror isn't going to solve a "tiering" problem.

In the "not supported" column it says:

FabricPool cloud tier (for S3 NAS buckets)
FabricPool local tier (for native S3)

So it is not supported to have ONTAP S3 as the cloud tier for Fabric Pool when using NAS buckets, and it's not supported to have ONTAP S3 as the local tier of a FabricPool when using native S3.

So yes, you could use FabricPool to tier your S3 data, but only when using NAS buckets (which is basically NFS with bolted-on S3)

Can't test it right now but if I remember correctly ONTAP won't even allow you to create a bucket on a FlexGroup located on a FabricPool-enabled aggr (local tier). But I might be mixing this up with another feature...

yeah, not sure if it is enough to have tiering-policy=none on the flexgroup or if you really need the aggregate to be non-FP... I would guess the former but I'm also not sure 🙂

I have tested it — it works. You can create a FlexGroup for NFS/CIFS, configure a tiering policy, then create an S3 bucket and map it to the FlexGroup.

#

And you can tier your S3 data to S3
