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...

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 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?

Proxmox HA, Docker Swarm, Kubrenetes, or what?

I’ve gotten to the point where I have more than a few servers in my homelab and am looking for a way to increase reliability in case of an update. Two problems: 2 of the servers will be on Wifi and one is a Synology NAS. I can’t do any wiring but I can put together a WiFi 6E network for the servers only, That means buying 4...

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.

Pebble Time. It was the best ever until the battery swelled. My Fitbit Versa 2 was good until the battery gave out. My latest Fitbit has worse software with less features than the last and I hate it. There are no apps available anymore.

johnnixon ,

Upvote for Pebble. It was the best of all time. I could operate the buttons without even looking.

Is there a source that doesn’t require me log into Twitter?

johnnixon ,

Thanks. Some screenshot of a tweet isn’t a source, but what you posted was.

johnnixon ,

When I heard the Fairphone 4 didn’t have any waterproofing I decided to skip this version. My coworker is replacing their Samsung S10 just because the USB port is getting loose but they’re an avid boater. For some, water resistance really matters.

Self hosted daily activity log?

I’m looking to replace the log book at work. I thought somebody must have made a simple docker container that allows someone to put in entries into a database for things like daily activities, guest logs, maybe even tracking fuel deliveries. Is there anything out there or and I going to need to remember how to make websites?...

johnnixon ,

I love Obsidian and have been using that for meeting minutes and study notes and even pleasure reading book notes. And homelab notes but things are always changing and I fall behind. But this is there to replace a shared paper book at the front desk. My users need more drop downs and less markdown.

johnnixon ,

The rabbit hole took me from Airtable to Baserow (which I have up and running but with the built in DB) but now need to make a viewer for the people. So the next step is visualizing the events list and filtering by day and whatever is needed to get useful info from the DB.
