Is Unity Deduplication pool wide

Question

Hello, I wanted to clarify if deduplication occurs on pool level or if it is on LUN level. ex. If I have multiple windows OS drives separated across multiple LUNs that have data reduction enabled will this data reduction take place on pool or on LUN level? The official documentation states that checksums are compared on the storage resource but eventually the data are written on the pool and that does not make it very transparent to me.

On Unity, it's done at the storage object level, i.e. LUN level or filesystem level.
