Hello.
I'm a novice in the IT. And I make a home lab. I looked that a lot of people prefer to set the proxmox to a slow ssd-drive and hold virtual machines on the fastest ssd-drives. What is the benefit to this way? Why I can not simply keep all these things on the same fastest SSD? I build 10Gbps LAN at home.
I ordered 12600h. Because I think it will be enough, and the electricity bill will be a little less. Also, I don't have enough space in my server box, and there is bad ventilation. So I'll have to limit PL1 and PL2 to the low TDP. I'll plan to use Proxmox as a host. And I'll use OPNSense in a virtual machine. Also, I'll use some home services in virtual machines such as DNS, HomeAssistant, and others. I don't still know that I need ZFS-raid on the M2 SSDs. I want a guaranteed boot up Proxmox and OPNsense. Can I use 1Tb from M.2 Big SSD with 2Tb on the pci4x4 and all the small M.2 SSD 1Tb on the pci3x4 to make a raid? Afterward, I want to use the remaining part of big SSD pci4x4 as a simple drive.
Which Coral TPU unit can I use instead of the WiFi module? Please recommend me. I want to use Frigate, and I want to learn it.
So many questions...
Putting proxmox on the slower ssd means more performance / space for your VMs but it is not a requirement just an optimization, depending on your use case it might not matter. Most nvme drives today can max out a 10G network, think about what kind of performance you need for your purpose and then decide where to put them.
You usually do not want to raid a 2TB and 1TB drive together as you will end up with 2TB of capacity at best for a stripe at the cost of reliability and only 1TB for a mirror though you will gain drive redundancy that way, either way your performance will be limited by the slower of the two.
The coal m.2 a+e key will work in the wifi slot, I have one in mine and have not had any issues with frigate and several cameras, you might want to think about more storage if you plan on retaining much video. Get the m.2 module with the single coral on it, it costs less and the dual coral will only show up as a single (no bifurcation). You can also pass through the iGPU to frigate in a LXC container if you do not want to use the gpu for other purposes (i.e. transcoding) and save the ~$25 it costs.
All that being said, your stated purpose is a home lab and labs are for experimentation, so try stuff out. You can always wipe it and do it differently the next time if you decide you didn't like how it performed.
