What's your server wattage?

I'm in the process of wiring a home before moving in and getting excited about running 10g from my server to the computer. Then I see 25g gear isn't that much more expensive so I might was well run at least one fiber line. But what kind of three node ceph monster will it take to make use of any of this bandwidth (plus run all my...

johnnixon OP ,

I looked at Epyc because I wanted to bandwidth to run u.2 drives at full speed and it wasn't until Epyc or Threadripper that you could get much more than 40 lanes in a single socket. I've got to find another way to saturate 10g and give up on 25g. My home automation is run on a Home Assistant Yellow and works perfectly, for what it does.

johnnixon OP ,

I'm afraid of dumping 500+ watts into a (air conditioned) closet. How are you able to saturate the 10g? I had some idea that ceph speed is that of the slowest drive, so even SATA SSDs won't fill the bucket. I imagine this is due to file redundancy not parity/striping spreading the data. I'd like to stick to lower power consumer gear but ceph looks CPU, RAM, and bandwidth (storage and network) hungry plus low latency.

I ran proxmox/ceph over 1GB on e-waste mini PCs and it was... unreliable. Now my NAS is my HA storage but I'm not thrilled to beat up QLC NAND for hobby VMs.

johnnixon OP ,

Where do you find the bandwidth to do all that? NVME eats it up and the 40g too.

johnnixon OP ,

What I need is a 10g storage for my Adobe suite that I can access from my MacBook. I need redundant, fault tolerant storage for my precious data. I need my self hosted services to be high availability. What's the minimum spec to reach that?
I started on the u.2 path when I saw enterprise u.2 drives at similar cost per GB as SATA SSDs but faster and crazy endurance.
And when my kid wants to run a Minecraft server with mods for him and his friends, I better have some spare CPU cycles and RAM to keep up.

Secure portal between Internet and internal services

I thought I was going to use Authentik for this purpose but it just seems to redirect to an otherwise Internet accessible page. I'm looking for a way to remotely access my home network at a site like remote.mywebsite.com. I have Nginx proxy forwarding with SSL working appropriately, so I need an internal service that receives...

johnnixon OP ,

I ended up going with tailscale. Every other option exposed my secret services to the Internet, even if behind a password. Tailscale was ridiculously easy to set up too. The docker compose I used had Heimdall in it too so I was able put all my links on there. Procedure is connect with tailscale app -> go to http://illegalshit -> click/tap on relevant link. I might pull back on my Nginx proxy targets and port forwards for this more secure system.

What happens if tailscale goes down though?

johnnixon OP ,

Late reply but yeah, Wifi was a nightmare on Proxmox. It was a tiny e-waste SFF pc so I was able to wedge it near the other servers. The cluster is happy.

johnnixon OP ,

I had to reimage through serial/USB then the Raspi OS properly downloaded the current image. Thanks for the links getting me in the right neighborhood.
