Techno Tim HomeLab Server Room Tour! (Late 2022)

[@TechnoTim]

What's your favorite thing in your HomeLab?

[@AchwaqKhalid]

The number of *CORES* 😎 And most importantly a silent setup 🔕

[@StarcoreLabs]

My Jellyfin server. It's open source, doesn't require an internet connection, and handles all my media without issue.

Well in the 4th quarter of 2022. I went from a single spare PC (5600G 32GB ram) and 2 pi4's to a full 48u rack, 2 Dell r620's (dual E5-2650l v2 [10c/20t], 64GB each), and the existing hardware I mentioned from before the rack... Hard to say what my favorite thing is.

Having built my first rack-mounted homelab this past year, I really like what you've done with yours. I included cable-mgmt as a design req't and that helps me understand a lot of the decisions you made during your upgrade. I like what you're doing on your channel...keep up the great work in 2023!

[@TechnoTim]

Thank you!

Thank you so much!

[@todkapuz]

I went to a rack this year and started the UI journey... and actually currently building my first dedicated homelab server... storage was mainly what I cared about before... but starting to enjoy thoughts of running some more services locally. Thanks for the great videos this year.

[@QuikTechSolutions]

Great network tour! Power in the front is very practical. Great work! Merry Christmas!

[@Yuriel1981]

*Slaps server rack. "You can fit soooo much networking in the front of this baby." Lol I love your set up. I never understood the power and networking in the back. It all seems much more workable when it's all accessible. Also Draco and Hydra may be the coolest sever names I have heard! I have my PC (Caspar) my daughter's PC (Melchior) and my mini home lab/NAS (Balthazar) on my home network. Named after the three wise men. Inspired by Evangelion.

[@guyboisvert66]

My favorite thing? The Supermicro servers with IPMI and lot of RAM! This is a very nice and very capable HomeLab... and even more because the way you're handling it with Kubernetes, Ansible and so on. It's nicely laid out, don't worry about what others think of it! I'm a old timer Sysadmin / Network Engineer who did many things in my life including using mainframes like Vax and Big Old IBMs, i used to have a Sun Workstation on my desk and rolled out the first bind DNS for the utility i worked for! I installed the first version of SlackWare using diskettes on a Dual Pentium Pro system! I installed the first Cisco Routers that looked like coming out of a garage with cards hooked with flat cables (the AGS / MGS etc) routing for a big network of Synoptics hubs (we had 18 000 PCs, 450 Routers, etc)! A bit after, we started to use Kalpana switches (later bought by Cisco). I'm now converting to containers and orchestration, state management and CI/CD! For the last 20 years, i did virtualization firstly with VMWare and after a while, i converted to Xen (on CentOS) and just a bit after, to KVM. I did a lot of scripting for automation, replaced now with Ansible. I found your very good videos wandering around on youtube: I'm learning a lot from you and i like youngsters sharing their great passion for techno! I learned all of my life and i still do everyday, that's the essence of what we do. Kudos for the very good information you're sharing!

[@techaddressed]

Favorite thing in my homelab - my cluster of mini PCs (which is most of my lab currently). Thanks for being one of the best parts of my 2022!

[@DesignerDigital]

The level of how nicely and clean it look is outrageous. I hate it, it's just amazing and I want it XD

[@betterwithrum]

'especially PBS' is about the most Minnesotian thing anyone from there can say. Being from Lake Wobegon, naturally it's MPR for me. ;) Happy Holidays Tim!

[@razvanilea]

Your Chrismas Tree looks wicked with all those switches and servers hanging, Merry Christmas!

[@playeronthebeat]

I'm so exited starting with my proper HomeLab this year, too! I have a server lying around a friend gifted me, a couple of Raspberry Pis. I'm planning on more security for my flat as well as more NAS storage and better/faster one, too (mentioned in another comment). I'm also thinking about the enclosure, as my HomeLab will also be the heating element for my terrarium. But 27°C seems like a dream (and the perfect heat) :D I was always fascinated by racks and rackmounted gear. I'm also thinking about rackmounting my PC even though, I do love it standing on my desk, too!

I've been waiting for this year's tour! It's amazing to see how much your setup changed in a year. The editing also improved a lot since last year. Proud of you boi.

[@TechnoTim]

Thank you so much, on all fronts!

[@kylehazachode]

My main project for the past year was to make custom length IEC power cables. I wanted to get rid of all extra slack in my racks. Almost all of my racks are mobile racks for live music and a few hifi vintage racks. I shortened all my power cables to the perfect length in my racks, and replaced the normal IEC plug with a locking plug. These locking IEC plugs are a godsend.

[@granttaylor8179]

Very nice setup 👍 I picked up an Intel NUC 9 Extreme this year to use as my Virtual server host. I moved over 64GB of RAM and a 1TB Samsung 970 EVO Plus. It is pretty quiet and does not take up as much space as the pair of smaller NUC's that I was using. The Dell Poweredge R210 II that I have was upgraded to 32GB or RAM and has a 1TB Samsung SSD boot drive and a 4TB WD Green drive to backup my VM's from the NUC 9. I sold my old 4th gen NUC & moved the 7th gen NUC downstairs to be my Plex server. I am happy with this now the Plex server is running Windows Server 2019 Datacenter with a pair of Samsung SSD's and 32GB of RAM. The NUC 9 was a steal at 50% off list price. The NUC 8 that was my day to day Hyper-V server has been rebuilt with 48GB of RAM and a spare 1TB Samsung 970 EVO Plus. It is running Windows 11 Pro and is my go to machine for browsing the Web and listening to podcasts. I can also spin up the odd VM on it for testing before moving them to the NUC 9. I do not have anything fancy as far as switches. I invested in a Cisco CBS250 16 port fanless switch and got a TP-Link DECO mesh Wi-Fi unit with 3 units in the box. This sorted out my Wi-Fi issues out and also sped up my data transfer from my machines upstairs and my Plex server & my Dell backup server. I like that the NUC 9 has a pair of 1GB Intel NIC's on board. My next project is to get Pfsense virtualized under Hyper-V and see how that performs. I would love to get a second Cisco switch to replace the cheap slink that I have connected to the Dell Poweredge. The NUC 9 with it's 45W 9750H i7 with 6 Cores and 12 threads is a great small system for a Hyper-V server. I would like to run some CAT6 between my router and my office upstairs and my Dell server under the stairs but for the moment the mesh Wi-Fi will have to do. I was using home plugs before but I was getting transfers if 10MB Per second between my systems upstairs a d my Dell server under the stairs. Now I am getting up to 52MB's per second. When you could be moving 1.5TB of files a 5x improvement in data transfer speed is a great improvement.

[@brentelieson1527]

TechnoTim, I really enjoyed your video! You have a lot to be proud of and share. By way of background, I have built many large data centers even receiving a national ASHRAE award. I've been running my home lab since 1993 and am going to be making a few changes to my 42U home lab cabinet as a result of your video. Thank you. The white rack and cabinet lighting is something I remember seeing at EBAY's data centers. Visibility in the rack makes work more efficient with less mistakes. I do have a couple of suggestions for you. #1 I would get a 4" ladder or more likely basket tray to manage your umbilical cord line from the wall to the rack. (Cabling does best in established pathways.) You could convert the resulting excess cable length into a service loop on top of the rack to allow the cabinet to still move around. Maybe secure the basket tray to the wall control and ceiling suspended just above the cabinet? I installed a 4" wide x 2" tall white basket tray while back that worked out really well. #2 It looked like your Philips Hue lines may be breaking one of my personal DC rules. Never "bundle" 110/220 and UTP together. I have many sad networking stories and A/B test results that inform this opinion. You have done an excellent job of separating out the two cable types otherwise!

[@TechnoTim]

Thank you so much! I had no idea what to do with the umbilical cord! This is a great idea! I am just trying to figure this all out with little to no experience besides the internet 😀

[@brentelieson1527]

@@TechnoTim Your server room is amazing. I've never seen a server room or data center that was perfect (especially the ones I've done). ha ha. You have zero to be apologetic about.

[@TechnoTim]

Thanks man! Haha! I am sure your wiring job would be much better than mine!

[@drumer2142]

I loved your tour and you Inspire the homelabers to improve or iterate ideas and try new things. What I would change in your setup as a next upgrade is to have layer "Core-Distribution-Access" without the complexity of a data center.

[@travisaugustine7264]

I just ordered a UDM SE. I'm slowing building a few new systems to replace what my OpnSense powered router/firewall can do (like local DNS override -- hello PiHole) before the UDM arrives at which point my entire infrastructure is getting nuked (from space) and I am starting over. I would love a walk through of your current config and setup, firewall rules, etc if you're looking for a video idea before sometime next week when my UDM arrives. Thanks for what you do, I've implemented a lot of your ideas. Now if only I could get my wife to get an RGB server rack LOL. Merry Christmas and Happy 2023!

[@Nur__]

it'd be great to see you add solar to make the lab green. Maybe add some batteries as time goes on.

[@hw2508]

Looks great and is always work in progress. If you ever touch the cables running to the rack, consider to 'mount' them to the ceiling. That would give you clearance to walk around the rack.

[@Feed9Will]

Very nice. Yeah enclosed rack does trap that heat - one way to turn it into a positive is to duct heat out of room. My summer temps are high. On my 24u open frame I got thick grow plastic + magnetic tape to create rear side "panels" to help contain heat right at servers' exhaust. Then picked up inexpensive infinity booster fan + duct to exhaust heat outside with AC window kit. Sits right behind 3x 2u servers. Works well to not keep recirculating heat. That and a 20' king air house exhaust fan sitting in window 5ft away from rack to cool at night. :) Not sure your heat situation in summer but perhaps outside exhaust solution could help with enclosed rack. AC works too. On another note - slim CAT6 cables patch work making me want to spend $.

[@TechnoTim]

Great idea! I wish I could fine a clean way to seal a duct to my block window vent! Any ideas?

[@acubley]

Scared to ask: what's the power bill? :-) Also, what's the music @ 0:52 ?

[@popquizzz]

Tim, very nice setup for a home network rack. I'm not much different but definitely less compute and storage. I am somewhat lucky to be able to do my home lab in an area where the cost for power is the second cheapest in nation at 2.6 cents per kilowatt hour. Where and how are you forcing the hot air out too? Are you having to install any active cooling?

Great video. I like the organization/labeling. Something I’d recommend is a labeled. I really like the brother p-touch. Can print wire labels as well as larger labels.

[@Jak835t]

I did not check if you use homeassistant yet, but wouldn't it be better to have your zigbee antenna, connect directly your hue/zigbee lights to your server (through zigbee2mqtt) not use the philips hue hub? So you don't rely on philips network, don't need 2 hubs, your lights work without internet and turning them on doesn't need to rely on the speed of internet connection?

[@nilocray]

Love your setup, I have just one question on average how much power dose this setup pull. I did have two dell severs running proxmox but had to retire one due to rising electricity prices. Have a lovely Christmas.

With the release of K8s 1.26 it is now possible to have a service of type loadbalancer and mixed tcp and udp protocols. That allows me to have a 3 node Pi4 K3s HA cluster (thanks to your ansible playbook) and PiHole finally inside the k3s. Longhorn has currently in the version 1.3.2 some breaking changes with k8s 1.25 and up. I had to use the master branch of longhorn to get it to work in k8s 1.26. They plan to have it fixed in the release 1.4.0.

Awesome set up Tim

[@ajma]

Can you post a graph of your rack's power usage over a 24 hour period?

[@ahmedifhaam7266]

Hi, how did you ground your patch panels, they seem to have shielded keystones and you are running PoE through them? This sometimes causes leaks into the rack, have you dealt with that or? Also, why not a single node with dual socket? Doing separate 1U servers is going to draw more power, more components etc. Lastly, in your previous video talking about UPS, you showed they had numerous sockets on it themselves, producing simulated or true sine waves and have grouped outlets on them as well. So, by using separate PDU, does that take away the advantage of that? I thought there were PDU's where you can get dedicated inlet for each outlet? So, to make full use of the UPS. Last question.. as a software engineer do you feel like homelab takes away too much time from your actual career or it feels like an addition? Thank you, Just asking, nice video man.

[@latticelinux]

I have been racking gear for years through my IT travels including in corporate data centers. The networking and cabling is usually done in the back as all the connections for the servers are in the back. Most people need all the U's in their rack and cannot justify the cost or the loss of the U's to do everything in the front. You lost two U's for the keystone pass through and then the cost of that setup. Some gear you can share U's by putting one in the front and one in the back. Assuming that is possible here you also lose U's for that. Doing this in the home is fine but you will not see this in an actual data center or corporate setup.

[@jonathan.sullivan]

Great update and upgrades. I'm slowly moving away from Ubiquiti as an edge device option and back to Pfsense/OPNsense. Ubiquiti just lacks creature comforts like HAproxy and other simple services. I will miss the pretty UI graphs but I just dump everything into grafana. Currently have a UDM-PRO that I'll be selling to cover the UNVR to run my cameras and protect. I'll virtualize the controller to manage my AP's and SSID's. Got a killer dream on a Netgate XG-7100 that will be running Pfsense/OPNsense, it'll handle my vlans and dhcp duties as well as the previously mentioned HAproxy.

This is an excellent video. I'm looking at moving my home equipment from a bookshelf into a rack soon. I'd be very interested in a video on the PDU Pro, particularly with failover with multiple UDM Pros. Thanks for addressing the RGB lighting as well. I've definitely fumbled around in a few racks that were a bit too dim or had areas that fell into shadow. Lighting strips seem like a great way to solve that problem. Perhaps the RGB color could be tied to rack temp for added utility???

[@coletraintechgames2932]

Tim. You the man. This is all very nice. I think the cabling looks great. If Tom Lawrence or Mac Telecom redid the wires, I would wonder what could be done better! I hate to be "that guy" but my only concern and I couldn't quite see, is the umbilical cord coming in on the top, is that going to rub on that metal edge? Won't happen overnight, but that is my only thought. And part of the reason it's my only thought is I am leaning from you! Lol I have no idea what I'm doing. Lol Thanks for everything.

The Amazon listing for your rack says it is 42U - but unless you are a giant, there's somethign fishy going on. My 42U rack here is significantly taller than I am, and I'm not short. I'm not sure how tall you are - but I would guess your rack is only about 36U. The rest looks really good - better than most of the racks at work. The only thing that would get you in trouble is your "umbilical" - that needs to be suspended up high enough to walk under. Best would be to have a little piece of cable-tray stick out from the wall, and just have a round on the end to control bend-radius and let it all drop to the rack. Easy to just drop new cables into the tray as needed in the future then.

Holy patch cables batman. Looks great but what all do you have hooked up that you need ~48 ethernet cables throughout your house?

[@HunterGeophysicsAustralia]

The brush that covers the hole at the top of the cabinet where all the CAT cables enter the cabinet - what's that called? I've just bought a Serveredge cabinet and it has the same slot for CAT cables to enter the cabinet, but it's just a rectangular hole without the brushes so dust and insects can easily get in. I'm hoping I'll be able to buy something I can use to help cover the hole around the CAT cables. (Sadly this is my first ever cabinet so I have no idea what the correct terminology is) Thanks in advance.
