Finally getting back around to setting up Proxmox to take over for the heavy-handed (and slightly expensive) vSphere VM/container hosting on my NUC cluster.

TIL that while vSphere/ESXi is fine running the OS off of a thumb drive, Proxmox very much isn't.

Made a "quick" trip to Microcenter to pick up some cheap NVMe drives and external enclosures (internal M.2 and SATA slots are being used for the Ceph cluster).

This Is How We Do
Mostly a note to my future self, but this is the guide I followed for getting Ceph going with tiering (replacing HDD with SSD and SSD with NVMe). Instructions are a bit outdated for Proxmox but work for the most part.

Who will win: Three little ole firewall ports or one human person?

(turns out NFS doesn't work on QNAP if you don't open 30000-30002, oops)
