Probably run up to 15x NVMe (U.2) drives.
I'll keep it sync'd to a spinning array ...
Use some special vDevs ...
Probably start off with 4x 8TB NVMe drives + some optanes
And a special vDev for small files of optane only.
I've thought about making a nested set of RAIDz2 zVols as constituent vDevs to make a 3x zVol so I'd have to lose and fail to recover one to lose data.
My anticipation is it won't be as fast as I'd think for some reason ? Between this and my spinning array syncing it, (and a DLT eventually) ... seems pretty safe.
I'm here just looking for an Epyc 2u with 24 slots .... but I'm always open to hearing how dumb I am.
