My lab:

My "little" lab is all over the place and the weird choices are made since I usually get my stuff from friends (of friends)/family (of family) for free or cheap. I have quite a lot of servers, in example, but only my main server is powered on 24/7. I usually have the other ones off, but since noone would want to buy them, I will keep them in my rack for testing purposes if I ever need something. I am planning on doing a movie night using Minecraft Paintings for example, that takes like 100GB of RAM, and since I have all this old crap, I can run it.

Rack from top to bottom:

My rack of choice is a second hand music rack which I bought for 20 euro's.

On top: Marantz AMP, Marantz tuner and surprisingly, a Marantz cassettedeck.

• Marantz AMP 1090.
• Marantz Cassette Deck 5010B.
• Marantz Tuner 2100.

Unit 1-3: networking

My networking gear is all over the place. First internet goes into the UDM Pro, then to the Netgear ProSafe GS748T and UAP-6-Lite. Via the TL-SG1024 is currently how my entire home gets internet.

Routing:

• ISP Router (outside the rack)
• UniFi UDM-Pro.
• MikroTik Routerboard RB2011UiAS-RM.

Switching:

• UniFi USW-Flex-Mini.
• UniFi UAP-6-Lite.
• TP-Link TL-SG2109WEB for the gigabit devices (outside the rack).
• Netgear ProSafe GS748T.
• ISP AP's which I already had before the lab (outside the rack).
• Powerline Ethernet for the TVs and printer.
• Patch panel (22x Cat6A, 1x HDMI, 1x empty for USB-C currently).

Unit 4-9: Server and NAS drivebay

• Main server:
  • AMD Ryzen 7 2700X (ML240Lv2, 1.8-4.8GHz).
  • G.Skill, 48GB RAM (2x8GB 2133MHz, 2x16GB 3000MHz. Both CL16).
  • ASUS ROG Strix B450-F Gaming.
  • NVIDIA GeForce 210.
  • 120GB SATA SSD (boot drive)
  • 512GB NVMe SSD (Jellyfin + cache drive)
  • 8TB raw for MDraid:
    • 2x 2TB IronWolf NAS. (array)
    • 1x 2TB Toshiba Canvio Basics.
    • 1x 2TB Seagate Expansion Portable.
• Second server (old HP Z400 workstation):
  • Intel Xeon W3565
  • 16GB RAM
  • GeForce GTX 750 Ti
  • 500GB 15K boot & Proxmox HDD).
  • 3x 1TB for backups

(OOU) Some drivebay for my server.

Unit 10-bottom: servers

• Spotify for Marantz system: Asus K56CA Laptop (i5 3337U, 8GB RAM & 16GB USB drive).
• Currently no use: SuperMicro 2U server (2x Xeon E5-XXXX, XXGB RAM).
• Currently no use: HP ProLiant DL160 G6 (2x Xeon E5640, 4GB RAM, iLO doesn't work & 250GB HDD).
• Minecraft Server: HP ProLiant DL380p G8 (2x Xeon E5-2630, 128GB RAM, iLO 4 Advanced & 300GB HDD).

Outside the rack

• Access points in the house: ISP AP's
• TV PC: i5-2320, 8GB RAM, GeForce GT520, 120GB RAM.

I use my lab for:

Learning:

 * i.e. different protocols such as DMZ, DNS, IPv4 and IPv6, PoE and many more.
   * DMZ for my UDM Pro behind our ISP router thingy.
   * DNS for Pi-Hole.
   * IPv4 is currently the default.
   *IPv6 is in the works-ish.
   * PoE for my APs.
   * Many more.

Deploying:

  * This website along with a few others.
  * Docker:
      * Various frontends for i.e. Reddit and YouTube.
      * Jellyfin.
      * Home Assistant:
          * A few WiZ led bulbs.
          * Tuya lights.
          * Shelly Plug S.
          * Thermostate system.
          * WoL for my PCs and servers.
          * Spotify.
          * Printer metrics.
          * Server metrics.
      * Portainer.
  * OpenVPN.
  * SMB shares (locally ofcourse).
  * A Git server.
  * Cockpit.
  * 'Work'
    * A 'development environment' (Neovim/SSH).

The services in detail:

• My server runs Debian GNU/Linux.
• I use MD raid along with ext4 filesystems.
• I use NGINX to host, reverse proxy and cache web related stuff.
• I use SSH and OpenVPN to tunnel back home if I'm away.
• I use Portainer for management on the few Docker containers I run (around 20).
• I use SMB shares for backups on my parents' machines over LAN.
• I use Home Assistant for my smart lights, our houses thermostate and a few more things.
• I use LibreX as my search engine.
• I use OVH SAS for a VPS to proxy traffic through (port 80,443 coming into my network).
• I use mostly UniFi gear since it just works
• My lab draws about 50-100 watts from the wall. Total, in the entire house (this excludes light bulbs and thermostate, but includes all 24/7 runnings servers and networking gear).

Future:

• I am aiming on adding more UniFi stuff, specifically more PoE and APs.
• More advanced switches since they're cool as I've heard.
• Better backups (looking into rsync.net, Kimsufi, and encrypted backups to GDrive or something similar).
• PXE booting, because I can.
• I am planning on making some sort of NVR system.
• Better WiFi coverage, currently have about 60% coverage.
• A lot more.
