Pretty much. I do what a lot of ISPs consider t2-t3 support and I get calls from super users all the time accusing us of having problems when all the problems are on their LAN. Yeah having a well-done network with VLANS, a real firewall, POE switches to cameras and APs, a pihole, ect is awesome, but it requires a ton of knowledge to design and maintain. IMO the most your average person should do is a mesh with a wired backhaul, or a Ubiquiti setup with a POE switch to AP's where everything is made easy with a GUI.

Seeing Dan just magically appear in the doorway with a tape measure while Linus is just talking brought up some uncontrollably loud laughter. What is it about Dan that is just so wholesome and yet also hilarious at the same time. The fact that he actually knows his shit is irrelevant! This man needs an Audio and Tech themed Stand up show ASAP!
Dan has impeccable comedic timing. I second the Dan show, but feel like maybe being a sporadic guest is the best for him. Either way, we all love seeing him on camera!
Dan's entire reaction as he goes "But... I told Gary 20 minutes....." is gold, I just can't help but feel sorry for him having to suffer through this and realizing he gave a promise he couldn't deliver on
I think Gary partially knew what he was getting himself into when he signed up for this job, It was never going to be actual equipment failure that would limit him. It was always going to be Linus and Jake

Technology is important, and information is power. I'm a farmer too, in the United States, and I have a server rack. Nothing as big as this, with as much hardware as this, but a lot of my farm is data-driven and I have a lot of machines all across my property sending data to a central location with software I run to give me a high level view of what's going on currently and historically, so I can make good management decisions and maximize productivity of my plants and animals. Every bit of passively and actively collected data I can think to gather, I plug into the system, and I write programs to help me make sense of it with statistical analysis and alerts for anything unusual that I might want to take a closer look at. Then I also have my home network on the same rack, back-ups for personal and professional data, etc. Next PC I build I'll put on the rack as well, and keep the noise and heat away from my desk.

interesting until you have to do it and nothing has been labeled by the previous person who worked on it, which more often than not nothing is documented.

It's really makes you wonder why they don't have a pro at this point. You know that they are really not networking or design professionals the moment they decide to move the switch from the back of the rack to to the front and don't think about whether the flow is front to back or back to front.. Either they didn't actually pay attention to airflow direction or they don't understand it plays a part in rack design. This type of thing makes for better videos, but their lack of real knowledge and cost effectiveness is painful.
I have to say, they got a custom extralarge rack...and it's utter sh*** compared to the ones I just put in that were off the shelf Rittal - those had space on both sides for cables, PDUs, and none of the issues they had with this. (Also, the way they moved it gave me serious anxiety as well).
I love that its clearly visible how enthusiastic Jake is about all the Network stuff and how its set up, to the point that even as someone who doesn't neet any of that goes "Hell yeah thats sick!"
Small but important detail when moving switches from the rear to the front of a rack: pay attention to the airflow direction! Notice that when Linus pulls out the fan module it has an arrow pointing inwards. I.e. this switch is configured to pull in air on the PSU side and blow it out the port side, hence it's intended for installation in the rear of the rack. Probably not a huge problem in their server/network rooms; but when you have a hot/cold side setup it can really mess up cooling.
18:30 Hi Jake! I work in underground utilities. If a building's internet goes down, it's either a cut service or a cut backbone. If ya'll get both services from the same ISP, there's a good chance a disruption to one service will be a disruption to both.
Rogers and Bell both had outages in the past 20 years where they had one cable somewhere, and a backhoe cut the line or someone applied a software update and ooops! Nothing works suddenly. Test labs are expensive, that gear is expensive, and it's a bit like insurance, right? What are the odds something catastrophic will happen? Aah, I think we can delay buying this piece or that piece the lab keeps pestering us about... Who cares right? The MBAs just want their next promotion somewhere else, right? While things run well no one notices but when services vanish suddenly everyone wants to talk to the IT staff.
I visited a major satellite ground station once that was supposed to absolutely never fail or have interruptions. The infrastructure was really interesting, their power came from two separate high voltage grids and they had three internet connections, two classical fiber optic links (different providers) as well as a free-space radio link to a station on a hill several kilometers away. Of course there were backup diesels to provide power in case of outages, but the generators would take some time to get up to speed and they didn't trust battery backups. Instead they had two flywheels with several tons each constantly spinning in case they had to bridge the gap between both grid connections failing and the generators coming online (with some of the big dishes drawing a few 100kW). They've been running for a few decades and never had any downtime so far. Simply insane engineering
@gnarflord4547 that's incredible, I love that one of the best ways we have of storing energy for emergencies is a big hunk metal spinning very fast lol
Absolutely fascinated by the rack and network videos! As a network engineer, watching the Guys evolve step by step is a joy. It'd be amazing to see a CCIE or another senior network engeneer take on the challenge of designing the network.

Simple 3 tier architecture. Multi chassis core and layer 2 down to the access layer. No need to over complicate it. I’d start with getting rid of the unifi shite

I have wondered every time they do a networking/server video what 'obvious' things they're missing due to not having an actual network engineer having contributed to their infrastructure.
@@billyashworth3944Jake is honestly impressively accurate on a ton of the stuff they build out given a lack of formal training or experience. All the redundancy stuff feels pretty quaint with my experience in the Enterprise Cisco world. Without digging into the particulars of the Dell setup they installed it basically seems like stackable layer 3 switches.
@@billyashworth3944The VLT could have been explained better. LACP is not the "combining" of two links into one, it is a control protocol for the underlying tech (ether channel, lag, etc) and bridging it between two distinct switches is typically called MC-LAG (Multi-chassis LAG), but for the target audience I think they explain everything appropriately. I am sure there are other "issues" but this I think is meant to be more high level and getting to the nuts and bolts isn't required.
As a network engineer its cool see you folks try to build a proper network. Not a bad idea Jake with redundant comms from either building thats how it should be done.
I remember setting up redundant backbone switches back when 1gbe was used for your backbone and server links, and drops were 100mbps. Good old purple Extreme Networking switches. So each server had 2x LAN cards, with each card connected to a separate gigabit backbone switch. The there were 2x gigabit links to each IDF. The final switches for drops in the IDF were 2x gbe (one going to each backbone switch) and 48x 100mbps - so the drops weren't redundant, but we had cold spares and having 48 drops down for an hour wasn't a big deal compared to the whole network going down. Also we had a SAN with 120x 15,000 rpm Fibre Channel drives that rivaled the size & performance of a modern SATA SSD but cost as much as a house. Back when EMC was still it's own company. Finally, remember that the point of cable management is to make work easy, not to look pretty. Sometime those align, but there's nothing worse than spending 20 minutes moving a single patch cord because someone used cable wraps every 3 inches. THAT is how you end up with a bunch of patches in your rack connected to nothing - "screw this, I'll just run a new one and unplug the old one". It's interesting to see how much some things have changed, and how little others have.
I appreciate all of you at LMG for making these types of videos. I love, not only the very in depth projects like this, but the fact that you make networking equipment fairly easy to understand. As an IT student these types of videos really help my understanding of network equipment and funnily enough, I am currently in my introduction to networking course. You all are the reason I am into computers and network equipment and I can't wait to get my degree to work on actual networking equipment and computers in general. Keep up the great work, you will always mean so much to me, in a not weird way lol edit: I guess I should add that I have been watching this channel and the other channels from back when the studio/office was a house and all of your equipment and cebles were running from room to room throughout the house. There were absolutely no cares for design and it was great. You had a background for filming and the equipment was adequate enough for the, I believe, two channels at the time LTT and ChannelSuperFun I believe were the two OG ones.
It's been fun studying for the CCNA and going back and watching all the old networking videos to see what stuff I didn't really understand while watching them the first time
I'm a mechanical engineer from Australia. I've been watching for years.. and can confidently say. I still have no idea what you're talking about, but kinda understand maybe.. networking is definitely a beast on its own and you guys are almost brilliant at explanation and use of what you're showing in these vids. Lol
I mean, they also have no idea what they're doing so that might help :P While entertaining, it is also often quite jarring to see how they still haven't hired an actual network engineer.
My network brings all the boys to the yard And they're like, it's bigger than yours Damn right, it's bigger than yours I can teach you, but the sponsor pays
As a former datacenter guy, it's always cute watching you guys ooh and ahh over enterprise equipment. Having worked with it so long, I sometimes forget how cool it is to everyone else.
I get that with my camera kit. To me it’s just a camera, but a lot of people haven’t seen a full-frame DSLR with a 2.8 70-200 on the front. I always get ‘how do you know what all the buttons do?’ I don’t.
Absolutely agree, always entertaining for the Linus crew to discover enterprise items that are minimums like the MLAG (I believe invented in 2010ish) but Dell...gross 😂
Worst part is trying to get that second Internet connection and having it on a completely separate circuit only to find out your local ISP’s all lease from the same parent company on the same cables
@@CheapSushi Or Starlink. I'm surprised they didn't consider that as an option. It's faster than 5G/4G LTE in theory and definitely on a different last mile link.
@@ky5666 starlink has the potential to work great, especially if they get the business plan. It would be a bit slower than they are used to, but the connection would be from Seattle; so its less likely both connections could go down at the same time.
@@ky5666 Considering the leaks from SpaceX, and Musks future prospects, I would probably avoid investing in infrastructure that is reliant on them. Not to mention the V1 vs V2 debacle
19:00 This is a game with sysadmins called: "I will propose something that is high availability, you'll say NO (which is fine), but I get to say HAHA why didn't we, at a later point in time." 😆

I'm happy to see real good looking cable management on network infrastructure on LTT, impressed from network rack size and features, redundancy feature and 100g
IT Mgr here for a very large automotive manufacture where we build everything with HA to keep the lines running, this is the step in the right direction for LTT. Some mistakes were made but overall good job guys.
@@votdfakThe company is making millions sure. Large automotive corporate entity is making millions an hour. Bear in mind that LTT's growth is significant over the last few years and that's why they hired an infrastructure specialist to help them tame this beast.
Very true but they're like Volkswagens. They just don't quit. I have several Dell switches at our Data Center and Corporate office. Alof them are 10+ years old and still running like a champ.
Love that you dropped "canyonero" in there. The song instantly started playing in my head and I haven't seen that episode in maybe a decade or so. Just waiting for you to drop a Mr plow reference now
Great steps in the right direction. We (the IT department I manage) embark on this project every five years at my company. We replace firewalls and switches if they're end of life/end or support. Good cable management and staying disciplined with routing and tagging cables saves you hours of work and headaches in the future, especially when transplanting/swapping hardware. I've dealt with the space limitations and cramming everything into a single rack. Undoing that 15 years ago was a nightmare. Never again, not on my watch. Good stuff. 👍
+1 for cable tagging - and double check that the tag is accurate, and then get another tech to check as well. A wrongly tagged cable is sometimes worse than a cable that isn't tagged at all.
Jokes on you Linus, I have 64 ports at 40 gigabit, plus 48 ports at 10 gig, and 48 ports at 1 gig. I mean it's all in my head, but you never said if the network had to be real Edit: nvm didn't see the 100 gig switch till now
@@LinusTechTips don't you guys consider building own game dev department? I think you can make some fun games. If you consider it please consider me as one of employees
Having installed many server cabinets into small rooms, nowadays I always take off the doors and side panels before moving it into a small room like that. Just taking off those will lower the weight by around 100 pounds.
That was an awesome blast! I for one look forward when Dan and Shawn are finished in the original server room with the cable management! Their cable management looks awesome!
I love the networking videos. Been keeping my eye out for the infrastructure updates ever since the first whonnock died. Love how you guys make the videos crystal clear and educational on each step. Also Dan and Shaun are legends! We need to see more of them 👌
Your ISP should be able to provide you with a second connection on an alternate path for your redundancy. You’ll be missing carrier redundancy but if the alternate path goes to a different POP you’re likely hood of downtime will be very small. Have the second path delivered to the lab.
If memory serves, they actually have a special agreement with their provider (shown in another video) where they are almost a peer, rather than a subscriber.
It's really cool to see how you add more and more failsafes and we see the entire thing develop over time. Thank you and the whole team very much for creating these videos!
I never get tired of seeing them work on their infrastructure. It's super cool to see what they were working with before and how much better it is after it's done. Of course since technology is forever progressing there's always upgrading and improvements to be had.
My house was similar. Built my networking rack under the stairs, eventually bought a taller one, then that's mostly filled, and now I have a second rack in my HVAC room to fit my Storinators because they're so deep, and that's mostly filled now too.
Linus, you are where my learning journey of redundancy started (and actually PC building entirely, largely from you). Banking all your operations on one switch! You know better! lol.
What Jake is really looking for is the deployment of VXLAN-EVPN, turn the building link into a 100G DCI (data center interconnect), internet in each building and VLAN can exist at both sites without old school stretching of Layer 2.
I know this’ll be random but seeing Jake go from the sorta disrespectful annoying younger guy at the office INTO an actual professional in relation to a variety of different technical and media style positions is awesome. I still remember that one video where Linus made a sassy quip about Jake and the comment section. I genuinely enjoy seeing these dorks grow over the years :)
Except Jake isn't an actual professional. Anyone with *actual* network knowledge wouldn't let him near a production network, even as a simple cable monkey.
@@AC-cg4be you’re misunderstanding licensed/certified for professional. If we’d like to be pedantic, I’m a qualified/licensed professional (graduate degree with state licensure) in relation to English, education, and counseling so I tend to go by the denotative meaning as opposed to the connotative in my writing. Jake engages these particulars with a level of competency that is above an amateur while being paid… the definition of a professional. If you’d like to argue that’s not the case then I’d contend you’re being disingenuous. You further narrowed the scope of my original comment into only networking. Is he as knowledgeable as others when it comes to that? Perhaps not. Or perhaps the way in which these videos are edited doesn’t allow for the full scope of his understanding to be shown. Anywho, I hope you have a good rest of your day :)
This is the content I subscribe for 😎 I’m a network engineer and trust me, you don’t get much content like this on UA-cam! With these speeds, make sure your Opnsense box doesn’t become a bottleneck. From experience these x86 firewalls can struggle at 10g+ when you start enabling some of the bells and whistles. Look into something like a Juniper SRX or Fortigate, those dedicated ASICs will let you go 25g+ intervlan no problem. Obviously if you’re doing intervlan just on the switch and not pushing it to the firewall then you all good 😊
I flippin' love the server videos! Not just to see Jake nerd out and Dan cry, but also because "enterprise" tech is an interesting niche that's not talked about very often compared to consumer stuff 😊 Also, welcome to the chaos-in-front-of-the-camera team Shawn!
As a network engineer... Dell Switches? Oh... Oh God Linus, why? Edit: Hearing the insanely stupid idea of paying for 4 Internet connections and then going into multiple routers for 2 buildings makes me wonder why on God's Green Earth that Linus has not heard of SDWAN.
He is making this switch an aggregation switch with the goal of doing intervlan routing so now there is basically zero network security and all vlans can talk with each other
Seems like your server room is pretty important to you :-) I always wondered why you don’t have a fire suppression system installed, like the one they have in colocation and server farms. Is it that you prefer water based sprinkler system instead of the gaseous systems we use in Europe?
I love that Dan just immediately backs up Jake on messing with Linus about there being a second rack. Doesn't even question it, total bro.
that is just what you do.
if you see a colleague messing with an higher up and they (kinda) believe them, you step in to confirm it and keep the ball rolling.
Just some fun things to do at work
I would pay a lot more for my networking racks too if they came with Dan.
And a good boss plays along so the company doesn't realize their boss is an android
True
Also jake is looking a lot better now I can tell he's lost a lot of weight, keep up the good work bro
The tech nerd in me has been trying to justify a server rack of network gear for years but really my ISP provided modem is everything I need

Yeah, I'm in the same boat. I've been looking at a layer 3 switch, but besides that, I really have no use for a crazy homelab (...yet)
Homelabs are not about need. Go for it, have fun.
Well 99% of people don’t need this but it’s cool to have plus you can learn about everything while building

I have wondered every time they do a networking/server video what 'obvious' things they're missing due to not having an actual network engineer having contributed to their infrastructure.
@@billyashworth3944Jake is honestly impressively accurate on a ton of the stuff they build out given a lack of formal training or experience.
All the redundancy stuff feels pretty quaint with my experience in the Enterprise Cisco world. Without digging into the particulars of the Dell setup they installed it basically seems like stackable layer 3 switches.
@@billyashworth3944The VLT could have been explained better. LACP is not the "combining" of two links into one, it is a control protocol for the underlying tech (ether channel, lag, etc) and bridging it between two distinct switches is typically called MC-LAG (Multi-chassis LAG), but for the target audience I think they explain everything appropriately.
I am sure there are other "issues" but this I think is meant to be more high level and getting to the nuts and bolts isn't required.
I won't lie...I've kind of started building out my home lab...and just depth of everything that there is, is insane lmao
As a network engineer its cool see you folks try to build a proper network. Not a bad idea Jake with redundant comms from either building thats how it should be done.
Greg and Dan really got some father-son energy going on, love it lol

As stated in every video he's in, WE WANT MORE DAN! GIVE HIM HIS OWN SEGMENTS! MOAR DANNNNNN!
I remember setting up redundant backbone switches back when 1gbe was used for your backbone and server links, and drops were 100mbps. Good old purple Extreme Networking switches.
So each server had 2x LAN cards, with each card connected to a separate gigabit backbone switch. The there were 2x gigabit links to each IDF.
The final switches for drops in the IDF were 2x gbe (one going to each backbone switch) and 48x 100mbps - so the drops weren't redundant, but we had cold spares and having 48 drops down for an hour wasn't a big deal compared to the whole network going down.
Also we had a SAN with 120x 15,000 rpm Fibre Channel drives that rivaled the size & performance of a modern SATA SSD but cost as much as a house. Back when EMC was still it's own company.
Finally, remember that the point of cable management is to make work easy, not to look pretty. Sometime those align, but there's nothing worse than spending 20 minutes moving a single patch cord because someone used cable wraps every 3 inches. THAT is how you end up with a bunch of patches in your rack connected to nothing - "screw this, I'll just run a new one and unplug the old one".
It's interesting to see how much some things have changed, and how little others have.
I appreciate all of you at LMG for making these types of videos. I love, not only the very in depth projects like this, but the fact that you make networking equipment fairly easy to understand. As an IT student these types of videos really help my understanding of network equipment and funnily enough, I am currently in my introduction to networking course. You all are the reason I am into computers and network equipment and I can't wait to get my degree to work on actual networking equipment and computers in general. Keep up the great work, you will always mean so much to me, in a not weird way lol
edit: I guess I should add that I have been watching this channel and the other channels from back when the studio/office was a house and all of your equipment and cebles were running from room to room throughout the house. There were absolutely no cares for design and it was great. You had a background for filming and the equipment was adequate enough for the, I believe, two channels at the time LTT and ChannelSuperFun I believe were the two OG ones.
Haha, Dan measuring the doorway and making that face was hilarious
Jake is looking in much better shape. Good on him
Gary's the best lol would love to see him on camera more but I'm sure labs going non-stop hopefully we'll get to see more of him soon.
It's been fun studying for the CCNA and going back and watching all the old networking videos to see what stuff I didn't really understand while watching them the first time
I'm a mechanical engineer from Australia. I've been watching for years.. and can confidently say. I still have no idea what you're talking about, but kinda understand maybe.. networking is definitely a beast on its own and you guys are almost brilliant at explanation and use of what you're showing in these vids. Lol
I mean, they also have no idea what they're doing so that might help :P While entertaining, it is also often quite jarring to see how they still haven't hired an actual network engineer.
My network is much bigger than yours
My network can walk right through the door

It's got you screaming back for more

So, you noticed too. Cool… In denial.

Mine's like sticking a banana between two oranges
I was not expecting a SOAD reference, amazing.
I was about to say the same thing@@NocturneXIII
As a former datacenter guy, it's always cute watching you guys ooh and ahh over enterprise equipment. Having worked with it so long, I sometimes forget how cool it is to everyone else.
I get that with my camera kit. To me it’s just a camera, but a lot of people haven’t seen a full-frame DSLR with a 2.8 70-200 on the front. I always get ‘how do you know what all the buttons do?’
I don’t.
Yep, same feeling, I use similar grade tools on similar grade hardware daily.
Absolutely agree, always entertaining for the Linus crew to discover enterprise items that are minimums like the MLAG (I believe invented in 2010ish) but Dell...gross 😂
Worst part is trying to get that second Internet connection and having it on a completely separate circuit only to find out your local ISP’s all lease from the same parent company on the same cables
It’s all fun and games until you find out that both providers use the same last mile provider… sadly I know that feeling at work
@@CheapSushi Or Starlink. I'm surprised they didn't consider that as an option. It's faster than 5G/4G LTE in theory and definitely on a different last mile link.
@@ky5666 starlink has the potential to work great, especially if they get the business plan. It would be a bit slower than they are used to, but the connection would be from Seattle; so its less likely both connections could go down at the same time.
@@ky5666 Considering the leaks from SpaceX, and Musks future prospects, I would probably avoid investing in infrastructure that is reliant on them. Not to mention the V1 vs V2 debacle
Glad you finally decided to get redundancy. I work for Dell and install and configure these switches just about every day.
19:00 This is a game with sysadmins called: "I will propose something that is high availability, you'll say NO (which is fine), but I get to say HAHA why didn't we, at a later point in time." 😆
The graphic at 26:25 was a lifesaver! Kudos, I was kind of lost until then
Garry very casually and "very stealthy" preparing a First Aid kit is hilarious! 😇😏
Time stamp?
@@the_undeadit's at the beginning, when the editor put the text on screen introducing him, I don't have a timestamp.
3:55
at 2:59 the amount of confusion on Sammi's face. The kind of "I need to prepare for something to happen which is going to be inconvinient! Just nod and play along until they leave."
I'm happy to see real good looking cable management on network infrastructure on LTT, impressed from network rack size and features, redundancy feature and 100g
More of this whole dynamic please, it's just fantastic for understanding how networking really works.
IT Mgr here for a very large automotive manufacture where we build everything with HA to keep the lines running, this is the step in the right direction for LTT. Some mistakes were made but overall good job guys.
but that's common knowledge for any corporate business... this dude is making millions and it took this long to setup HA...
So clearly HA isn't the key to profitability...@@votdfak
@@votdfakThe company is making millions sure. Large automotive corporate entity is making millions an hour.
Bear in mind that LTT's growth is significant over the last few years and that's why they hired an infrastructure specialist to help them tame this beast.
Dell rails are definitely the best. The worst part is that all the internel components are Dell proprietary.
Very true but they're like Volkswagens. They just don't quit. I have several Dell switches at our Data Center and Corporate office. Alof them are 10+ years old and still running like a champ.
Tbh preferred HP rails but as HP cares only for language not actual good hardware now we had to switch (pun intended)
Arista switch rails are really nice and really easy to install. racked about 400 arista switches super nice.
Love that you dropped "canyonero" in there. The song instantly started playing in my head and I haven't seen that episode in maybe a decade or so. Just waiting for you to drop a Mr plow reference now
So I work for Dell, and it's nice to see you guys make a video where you're not completely ripping Dell.
As a data center cable tech all I can say is "MY EYES" to that one rack.
Great steps in the right direction. We (the IT department I manage) embark on this project every five years at my company. We replace firewalls and switches if they're end of life/end or support. Good cable management and staying disciplined with routing and tagging cables saves you hours of work and headaches in the future, especially when transplanting/swapping hardware. I've dealt with the space limitations and cramming everything into a single rack. Undoing that 15 years ago was a nightmare. Never again, not on my watch. Good stuff. 👍
+1 for cable tagging - and double check that the tag is accurate, and then get another tech to check as well.
A wrongly tagged cable is sometimes worse than a cable that isn't tagged at all.
you struck gold with Dan. He's great.
I love that at 25:50 Linus actually wants his employees to go home and stop working. Props for encouraging a balance
Overtime pay is a bitch.
Im a networking dummy but i always really enjoy these videos, the kaos and dynamics between jake and linus is gold
Would love to see more network upgrade and management stuff, will be great to see the main studio rack so much cleaner compared to the last 8 years :)
Jokes on you Linus, I have 64 ports at 40 gigabit, plus 48 ports at 10 gig, and 48 ports at 1 gig. I mean it's all in my head, but you never said if the network had to be real
Edit: nvm didn't see the 100 gig switch till now
got 'im! -LS
@@LinusTechTips don't you guys consider building own game dev department? I think you can make some fun games. If you consider it please consider me as one of employees
Ye and those 100G ports can breakout to 10x10g ports etc , cool stuff :) And then you look at top of line stuff like z9664f , with 64x400gig ports :D

Having installed many server cabinets into small rooms, nowadays I always take off the doors and side panels before moving it into a small room like that. Just taking off those will lower the weight by around 100 pounds.
That was an awesome blast!
I for one look forward when Dan and Shawn are finished in the original server room with the cable management! Their cable management looks awesome!
me watching this video in 1mb/s
How that even works
I love the networking videos. Been keeping my eye out for the infrastructure updates ever since the first whonnock died. Love how you guys make the videos crystal clear and educational on each step.
Also Dan and Shaun are legends! We need to see more of them 👌
My server can walk right through the door with a feeling so pure it's got you screaming back for more!

Your ISP should be able to provide you with a second connection on an alternate path for your redundancy. You’ll be missing carrier redundancy but if the alternate path goes to a different POP you’re likely hood of downtime will be very small. Have the second path delivered to the lab.
If memory serves, they actually have a special agreement with their provider (shown in another video) where they are almost a peer, rather than a subscriber.
most company has two ISP
@@WilliamHaggerty All the better, they just need the additional leg and a bit of BGP to get some site diversity running.
@@zhen86 Linus said he was to cheap in this video to pony up for a second ISP. 😂
Always love the server videos despite understanding maybe 10% of what you talk about
Complete respect to anyone that is so fluent in networking and to LTT team
It's really cool to see how you add more and more failsafes and we see the entire thing develop over time. Thank you and the whole team very much for creating these videos!
With four more Dell ON switches you can build yourself a speedy, redundant and easy to manage Spine & Leaf fabric just like the hyperscalers.
I love watching Linus and Jake working together, they totally have that bro vibe
I'm of the same mindset networking my house, Linus. Get it going, set it up and unless it breaks, never touch it.
This is very similar to something we did around 10 years ago at a Michelin plant. I never get tired of watching infrastructure videos!
one of my all time LTT favorite videos so far. So much fun to view, but really high end networking expertise going on. BRAVO !
“We didn’t think this through” defines every Startup IT department 😂
I never get tired of seeing them work on their infrastructure. It's super cool to see what they were working with before and how much better it is after it's done. Of course since technology is forever progressing there's always upgrading and improvements to be had.
Loved watching Gary & Dan the calm n collected duo in contrast to these 2 chaotic ones 😁
My house was similar. Built my networking rack under the stairs, eventually bought a taller one, then that's mostly filled, and now I have a second rack in my HVAC room to fit my Storinators because they're so deep, and that's mostly filled now too.
Linus, you are where my learning journey of redundancy started (and actually PC building entirely, largely from you). Banking all your operations on one switch! You know better! lol.
I saw that title and my Inner millennial went to system of a down "My server walks right through the door,
With a feeling so pure!"
Rofl😂
What Jake is really looking for is the deployment of VXLAN-EVPN, turn the building link into a 100G DCI (data center interconnect), internet in each building and VLAN can exist at both sites without old school stretching of Layer 2.
You know too much to be watching this channel.
@@BDBD16 their channel(s) is only for people who are less knowledgeable about computing or Enterprise IT infrastructure?
Hammond Manufacturing makes really nice racks. All of the racks I have at work are from them!
Thanks @asphere8
These networking videos are my absolute favorite videos you guys do.
Working in infrastructure, these are my favorite videos. Dan and Shawn do nice work.
I know this’ll be random but seeing Jake go from the sorta disrespectful annoying younger guy at the office INTO an actual professional in relation to a variety of different technical and media style positions is awesome. I still remember that one video where Linus made a sassy quip about Jake and the comment section. I genuinely enjoy seeing these dorks grow over the years :)
Except Jake isn't an actual professional.
Anyone with *actual* network knowledge wouldn't let him near a production network, even as a simple cable monkey.
@@AC-cg4be you’re misunderstanding licensed/certified for professional. If we’d like to be pedantic, I’m a qualified/licensed professional (graduate degree with state licensure) in relation to English, education, and counseling so I tend to go by the denotative meaning as opposed to the connotative in my writing. Jake engages these particulars with a level of competency that is above an amateur while being paid… the definition of a professional. If you’d like to argue that’s not the case then I’d contend you’re being disingenuous. You further narrowed the scope of my original comment into only networking. Is he as knowledgeable as others when it comes to that? Perhaps not. Or perhaps the way in which these videos are edited doesn’t allow for the full scope of his understanding to be shown. Anywho, I hope you have a good rest of your day :)
My network can walk right though the door.

Lucky that Linus is the owner/CxO. A fairly reasonable CIO would never let him near any server/network room. Ever.

I just nerd out over the Hammond enclosure. Quality choice there.
Thanks Ghost!
This is the content I subscribe for 😎 I’m a network engineer and trust me, you don’t get much content like this on UA-cam!
With these speeds, make sure your Opnsense box doesn’t become a bottleneck. From experience these x86 firewalls can struggle at 10g+ when you start enabling some of the bells and whistles. Look into something like a Juniper SRX or Fortigate, those dedicated ASICs will let you go 25g+ intervlan no problem.
Obviously if you’re doing intervlan just on the switch and not pushing it to the firewall then you all good 😊
Its a shame these videos are so short. Great content still
It's not about the length of the content, it's about quality
Like linus
@@p_serdiuk i know its about quality. But still, this is my favorite kind of content
I flippin' love the server videos! Not just to see Jake nerd out and Dan cry, but also because "enterprise" tech is an interesting niche that's not talked about very often compared to consumer stuff 😊
Also, welcome to the chaos-in-front-of-the-camera team Shawn!
As a network engineer the response “oh is it actually working?” Is a very accurate one in our trade 😂
As a network engineer... Dell Switches? Oh... Oh God Linus, why?
Edit: Hearing the insanely stupid idea of paying for 4 Internet connections and then going into multiple routers for 2 buildings makes me wonder why on God's Green Earth that Linus has not heard of SDWAN.
My exact thought lol
He is making this switch an aggregation switch with the goal of doing intervlan routing so now there is basically zero network security and all vlans can talk with each other
If you really are one, can you give me some info on the company Cisco?
@@hamzix6599I almost ask: Why even have VLANs if your passing traffic between them freely...

Redundancy as a Backup of a backup. Welcome to some Datacentre tech. Im dealing with those on daily basis. Great explained !!!
With the kind of operations you're running, you actually should have 2 internet connections, ideally from 2 different ISPs.
"in February it would have been 8 years" Bro counting the days 😭
Seems like your server room is pretty important to you :-) I always wondered why you don’t have a fire suppression system installed, like the one they have in colocation and server farms. Is it that you prefer water based sprinkler system instead of the gaseous systems we use in Europe?
Well, I sell them and they are cheaper than one might think. We use argon or nitrogen, since halon is banned since 2000
an older IT guy that isnt depressed working on a helpdesk! Nice to see
It's got to be nice having a company of tech people. Every single person is IT support - wonderful
