max aggregate size is actually based on the following (output from aggr show_space) from our findings:
This is calculated without the Parity Disks (they donâ€™t count into this total space) and matches with Synergy.
So it depends on RG size really, and according to Synergy, you can reach 399.45 TiB with 124 x 4 TB disks and a RG size of 18.

They use TiB on the 400T max aggregate size and GiB on the right size, so 3718 GiB is the right sized 4TB disk. That is where I was getting the 107 from.
They do say the aggregate capacity is based on right sized in writing, but buried in the â€œPhysical Storage Management Guideâ€, and everyone has better things to do (except me) than reading that!

400/3.815=104.85 is pure raw.
400/3.807=105.07 is right-sized raw.
Tuna, is best served, raw.

It is based on the right sized capacity. So if this was The Price is Right, the 105 would win. I think the actual answer is 107.

Marketing disk size (4T)
Raw block size (3.815T)
Which makes a 400T aggr either 100 disks, or 105.
Beer bet to settle here. :)
