> Does this value include the SG EC?
On ONTAP, ActiveIQ reports what ONTAP can see.
Using the S3 API (which is what FabricPool does), ONTAP can't get any insight on how SG protects its data.
> In addition to this I see a 12TB delta between the reported cloud tier size in Unified IQ Manager and the fabricpool value in StorageGRID.
It's not clear whether 12 TB is a lot or not.
12TB is a lot in a 100 TB bucket, but not much in a 1 PB environment. It could be deletion (TR-4598).
