Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

5 node proxmox cluster (each node on 40gbps networking[yes ceph...], ~80TB of SSD storage, 180cores, ~630GB of ram total)
1 slow storage node (~400TB)
2x opnsense servers in HA
2x icx7750s
2x icx7450s
PoE to all the things... and 8gbps internet.
Usually run ~15-17amps. So about 2000 watts. It's my baby datacenter.
Sometime this month I'll be installing 25000kwh solar system on my roof and batteries.
As far as heat goes... It's in the garage with an insulated door, heat pump water heater, and there's a tripplite ac unit in the bottom of the rack. The waste air(from the a/c) exhausts outside through a direct vent in the wall. The garage is downright tolerable to me for extended periods of time. The servers don't complain at all.
Reading about all you guys being under 200w or whatever makes me wonder if it's worth it. Then I realize that the cost to do even a 1/4 of what I do in the cloud is more expensive than buying my solar.
Power costs for the rack is about $100-120 a month. If it wasn't for solar.
Edit: 75 LXC containers, 22VMs.
Just out of curiosity, what do you use all that storage for?
On the Sata SSD ceph storage. That's just live stuff on the containers/vms. I'm at 20% usage of the 70TiB usable at the moment. I don't use it all that heavily. Because of the way ceph works it's really ~23 TiB of usable space and ~4.5 TiB written since it writes 3 copies in my cluster.
On the slow storage node it's running Truenas with 28 spinning disks at 16TB each. 2 hot spares, and 2 ssds each for cache, log, and metadata (eating up total of 36 bays). That's 342.8TiB usable after raidz nonsense. And I'm 56% usage. I have literally everything I've done that I cared to save from like 2005 or 2006 or so. Backups for the ceph storage (PBS). Backups for computers I've had over the years. Lots of linux ISOs(105TiB) archived, including complete sets of gaming (37TiB) variants. Oh and my full steam library as well which currently sits at 14TiB. Flashpoint takes up a few TiB as well...
