RE: The Post Your Homelab thread - Duvel - 2023-07-04

Now that's the thread Smiling-face
I'll post mine soon.

@Joshua what's the total power consumption of your install ? I think it has become a very important factor in selfhosting and everyone should specify it in this thread.
Man I am wondering if you have a field of solar panels to support your datacenter??? Grinning-face

I had a solid install for years and my whole rack was at 450Watts. I had to cut off everything last year because of the energy crisis in Europe. Electricity costs rocketed up (like 10x) and my bill had become unpayable.  I downsized mostly everything and now run at 100 Watts. I basically went from 32 cores to 4, from 15 VMs to 5.... and learned to rationalize services to the max Grinning-face

I run my Jellyfin server on a Dell Optiplex 5060 Micro. This is one of the 1 liter sized PCs and great for a home server. I got this off eBay for about $120 and it has Intel UHD Graphics 630 on an Intel i5 8500T (first generation i5 with 6 cores). Jellyfin runs with other apps in a docker-compose config. I connect 2 USB hard drives to the server and host all my content on those 2 drives.

Total power usage is somewhere between 1700 and 1900 watts depending on what I'm doing. Yes, it's excessive Upside-down-face . I don't have any solar for this (I do run some outside lights with solar though!) but I live in Ontario, Canada which is 50-60% nuclear baseload with a lot of hydro and wind so, even if it's not the cheapest power I feel good that at least I'm not trashing the environment with coal and such.

Ooh I'm currently adding some new bits to my homelab, so I'll post! Its an absolute mess right now, but it's my mess ❤️

From the top down:
- little legacy 8 port switch that I still use for POE, and yet is still somehow still the backbone of my network -.-
- Main 24 port 1g switch. It has two 10gb ports meant for uplinks but I'm using them to direct connect my main ceph nodes right now
- patch panel
- new (to me) 48 port 10g switch! Planning to bond 2 ports per virtualization/ceph node, and reorganize my network to use this switch as the backbone! Excited to get this project underway
- Hidden away is a little nuc running proxmox + ceph which acts as a tie breaker for my size=2, min_size=2 ceph cluster
- a supermicro box I'm colocating for work, office didn't have good enough Internet, and the server room couldn't dampen it's sound enough to not bug people. So I get to host it for now
- hp dl380 with 256gb ram and 16 cores x 2 sockets; this is my main virtualization box, along with the nuc (provides redundant DNS) and a tower out of frame (the other ceph node, zwave radio, and GPU for transcoding).
- old 4u I don't use anymore, want to move the tower I'm using into this case
- New (to me) server I'll use for virtualization and highspeed ceph pool. Thing is a beast, 128 cores & 700gb ram

Typing it out makes me realize it's even more a mess than I realized haha

Running inside are my core network services (like DNS, VPN, IPXE, and Borg). But most everything else runs in a kubernetes cluster with nodes spread across the hypervisors. Things like home assistant (zwave controller) and Jellyfin (GPU) have their hardware added to the vm, and then passed into the container. I use kata microvms for services exposed to the public Internet, along with strict network policies for all containers. I make use of metallb + bgp peering for IPs, ceph for storage (and cephfs makes for great ISO storage), and manage all the config with FluxCD, Terraform, and Ansible.

So yeah! It's been a wild ride. My goals next are:
- Reconfigure everything I can to go through bonded 10g DACs
- Move to a proper PDU to manage fencing in proxmox and track power usage
- Automate most disk encryption with a separate physical device running Clevis (and using tang)
- Better backup story. Currently the important stuff gets borged to a set of mirrored 18tb disks, but I love the idea of having a box I can grab and run with.

So lots to do in the new year! Love this thread, hopefully others can share their setups to give me more ideas ^^

RE: The Post Your Homelab thread - Beardyman - 2024-01-26

Those are some nice setups! I'd like to show mine off as well...

Meet Marshmallow and Liquorice:

   

Marshmallow, Proxmox server for main applications such as Jellyfin.
It's a Ryzen 7 5700G with 128 GB RAM, 8x 10TB in ZFS RAIDZ2 and a GTX 1050 TI for Jellyfin transcoding.

Liquorice, Proxmox server for backups and other stuff that doesn't have to run 24/7
Intel i5 10400 with 64 GB of ram, 4x 12TB in ZFS RAIDZ2 and a GTX 1660 Super for video game streaming to my living room.

Jellyfin currently runs inside an Ubuntu VM with 4 cores and 32 GB of RAM. There's a GTX 1050 TI with PCI passthrough which handles live transcoding for any non-compatible clients. I have somewhere around 20 users, mostly family and a few friends. This is connected to a 1 Gb/ps up/down line, gotta love that fiber :D

I'm thinking of switching the 1050 for an Intel A380 sometime this year, these are quite affordable at the moment and it will help me make the switch to AV1 codec and save A LOT of space... Most of my library (80%) is in x264, the rest is x265.
