Not to butt in into your conversation, just wanted to drop that me and my colleagues use what we call the “clone cars” method to combat our company’s naming scheme
So for example we dubbed CAPROD01 “Cappy” NASPROD01 became “Nasir” LTPDEV02 became “Luigi” (because he’s always number 2)
Of course in written communication we use the full name (which is much less of an inconvenience) and we always double check in conversation or spell out full names before doing anything critical

BTRFS is not production ready (by their own admission)
1 disk redundancy leaves you exposed whenever you have to rebuild … has significantly higer chances of having a second disk fail so you should use double redundancy. Raid z2 doesn’t make sense because with raid z10 you get performance gains AND double redundancy.
Go with raid z10
