I have two fundamental questions to help me get started on my build. I have 20 years background in IT/Infosec but have no experience with zfs/truenas/proxmox. My hope is that you can help me avoid some rework by making some basic setup mistakes.
First question: I have a server (34 core / 512gb ram) with 18 drive bays. My plan is to run truenas scale on it. Is it recommended to have 8 drives set aside for storage (8x18tb) in one pool. 8 additional SSDs (1tb) set aside and a separate pool for VM/Dockers. Remaining 2 drives for Truenas OS (raid1). I realizes this may seem a simple and silly question, but just wanting to make sure 2 pools, with two different drive types and sizes isn’t a bad idea. Googling seems to find lots of confusing forum threads which don’t directly map to my simple question.
Second Question: I have another server that I am considering using to learn and play with proxmox. If my VM needs are rather simple, should I plan to put anything I plan to use very long term on the Truenas box (above) since it seems migrating from Proxmox to Truenas isn’t easy? The second server is rather old and likely going to be expensive to run long term. I’d like to avoid lots of rework porting my Vm from the “learning” server over to the main server later.
