This video is a straight forward look at the network that was built for LTX 2023's Whale LAN. Both the video and my interview with Jake from LTT were both filmed prior to any of the LTT drama - I just didn't get it edited quickly because I was out on deployment with the ITDRC for a week helping with the PNW wildfires. I do make a quick statement about the LTT drama - mostly just a 'I hope it all works out' kind of thing...but other than that, this is purely a video about a kick-ass network, and has nothing to do with the drama that happened afterwards. So should I pull the video? Even though it has nothing to do with the current LTT drama, if it's gonna piss too many people off, I'll just trash it...I don't need the headache. Let me know by replying to this pinned comment please! I'll let this sit overnight, but if consensus is that I should pull it, I will.
I'm not the guy who leaves comments often, but please keep the video available. I could very well see novice network administrators learning a lot just from this. Seeing how a large event handles connectivity and what obstacles they face (like having to use the armored fiber optic cables). Thank you so much for taking the time to make this video!
LTT drama aside this is such a cool video considering jakes background. Jake started at LTT years ago and literally learned everything he knows on the job. I think he started as a small role maybe with logistics but learned all the networking stuff from Emily and has grown to be their network lead. Its very impressive how much he knows now and what he's accomplished given the non traditional training and now being a figurehead in the networking and tech community.
Yeah and he has a *TON* of stuff still to learn. I am sure every competent network admin was screaming NOOOO into the screen when he was sticking attenuators into LR optical links. They are absolutely not needed under *ANY* circumstance. LR optics automatically adjust the power levels of the laser to not burn out the photodiode at the receiving end. Oh and the continual storage disasters just want to make a competent storage admin like myself want to cry. They haven't the foggiest clue how to do it properly.
Its a good example of how far you can go with the right opportunity and drive. People forget that a year while it seems short, is a lot of learning if you immerse yourself. Teaching yourself to code, or learn networking, or cloud, or some other cool new thing... a year can bring a WHOLE lot.
Happy to see some love for MikroTik. They're totally underrated in the USA, IMO. Very commonly used for core routers in Europe though. I've got one of their 12 port 10Gbps switches on my home network.
@@ask_carbonyour comment is exactly a demonstration of the overreaction... How is a video on crosstalks channel being delayed or pulled holding LMG accountable?? You're so disingenuous. Do you want everything LMG deleted from the internet to never be heard from again? Will that make you happy? The parasocial relationships people have with online personalities is sad.
Your statement at the beginning was fine, I don’t see how this is affected by what LTT has done or failed to do. Not condoning it in any way but it would be a shame if we didn’t get to see Whale LAN because of bad actions by a few.
In the old days there were frequent "interoperability" demos to connect up different vendors. This over the top network is a great demo of the 100g future! Please have the whole configuration documented and benchmarked somewhere for us to study.
I had the pleasure of being there for whale lan and that network was perfectly stable. The only complaints were with the Wi-Fi but it looks like the convention center was broadcasting 1 million different SS IDs and basically took down their own network as well. Otherwise, it was running amazing and I would have bet money that they had more than a five-gig connection for everyone there just based on how well everything is working.
Cool to see a large bandwidth network at a smaller-than-data-center scale. This is the year when 800G port shipments are projected to overtake 400G ports as #1 in the datacenter, but >= 100G ports outside of the data center are not a common sight.
Hey! I know Kevin (with LANFest!). I am a network admin for another LANFest chapter. It's nice to see what other LANs like Whale LAN are doing. Thanks for the video!
Awesome vid! Keep it up. And well handled at the beginning. I hope LTT handles all the drama well and makes improvements. Whether you like them or not, no need to wish negativity on anyone. There is too much bad stuff happening in the world to wish ill on anyone.
Yeah... Even in our Enterprise - with (2-stacked) 4x100gb/48x25Gb Cisco C9500 switching and PureStorage NVMe, actually utilizing even like 50Gbps is hard. You might get peaks on each line at times, but to have all going at max is just not very common. Plus, a lot of Enterprise traffic won't even hit Layer-3 as it stays in the vlan (i.e. storage and vm motion traffic won't even have gateways) So overkill is true, but it was a cool design - the LANCache I agree was probably incredibly smart.
It's interesting that, although Unifi was the sponsor, they had to use a Mikrotik for the core switch. I wonder if UniFi are looking at that and considering a response product.
For the Proxmox server, he said they had a dual 100G NIC, so I might have used a breakout DAC to the switch and then a peer to peer link at 100G to the lancache.
They have (had?) a few products that would have handled that (well, in the UISP range, not the UniFi range) but as they're early access, I don't know if the terms would allow LMG to use them for the LAN
Overkill being cool aside, how might a venue build a network that meets expectations but is more conservative? The 200GB network wasn't really utilized could you have done it with 25GB? Also, the traffic, if truly maxed out, would be limited by the incoming ISP link, so yes, the catch server takes most of the hit saving that link. Chris, you should get your hands on some of that armored fiber cable and do a video. It looked interesting.
2:30 I'm glad you brought it up but decided not to pick sides or anything (but the tech side). Much better than a lot of hate that I am seeing from community to community. Let's all just stick to tech and give people some time :). Everybody makes mistakes :).
Interesting to watch. Curious how they managed the ip space. How many devices were there online. I was always told big broadcast domains are a no no so assume it was split up?
Two things I would love to have: (1) A link to the armored fiber cables mentioned (yeah I can probably find them, but call me lazy LOL), and (2) A link to the specific rubbermaid tubs that Jake said fit the Ubiquiti switches perfectly!
Cant wait for the Network Gear Showoff! Hope to get some time to Showcase my Offgrid Wifi WLAN/LAN setup for Offline Servers i use in the forest with Links and services with Spectators.
@@BenKickert Jake built out the network, and LTX has nothing to do with the controversy. I think it's fine. The community is WAY overreacting to everything in my opinion. The madison allegations are worrying, but I'm holding off any conclusions until the investigation is complete.
Please keep the video up. This was very entertaining to watch and the network gear is amazing to see in action. Plus it helps remind everyone that we are dealing with real people at LTT who aren’t bad people.
It's stupid you even have to disclaim anything about LTT. Canceling sucks. LTT may need to address some things, but guilt by association is so dumb. Love your videos, Jake is great, loved this video. Great work :)
This is cool and all but I would invite you all to set this sort of event up in Chattanooga TN at our convention center here. There is 25 Gig up and down fiber connection coming into the building. I actually work for the Fiber internet company here and we are on the lead edge of pushing speed to the limit. We even are pushing out quantum network security for our customers. Every customer on our network is able to get 1 Gig, 10 Gig or 25 Gig connections.
Dude! I saw an article about Chattanooga's Internet a couple of years ago and emailed in to see if I could come check it out for a video and no one ever got back to me...get in touch!
Unifi doesn’t fit everywhere, particularly when you get to real networks like this. I thought it was funny he mentioned issues with Ethernet SFP adapters. That’s also a fun problem with Unifi, had they used another brand of switches they probably wouldn’t have had issues. We use copper SFP adapters everyday in MikroTik and white box switches with no problems
Keep the video up I don’t see why you need to be dragged into the LTT drama by just covering their event/setup. If these people want to boycott they could nothing is stopping them but this is ridiculous to want other creators to not post content .
200 Gbps -- they can do that with a single port off of a ConnectX-6 card these days. (Or dual 200 Gbps ports for an aggregated 400 Gbps worth of bandwidth.) But if the peak traffic on the cache server was only about 10-15 Gbps - that's just "because you can" territory and not because there's an actual need for it. (I run 100 Gbps Infiniband in my basement. It's AWESOME!)
@@haxie4516 Fully agree -- especially if you don't have prior/historical data that tells you how much bandwidth you need to provision for. But on the other than, there's also an element to this which is "just because they can" since they already have the hardware available. I remember deploying a Sun Microsystems SunFire X4200 server with quad 73 GB 10rkpm SAS 2.5" drives for my private university's LAN party (ca. 2007) and I was using ZFS in Solaris back then, and to distribute games and game updates, even back then, over the quad GbE NICs that were built into the server -- and we manually assigned different rooms to different IPv4 addresses to manual load balance the NICs (we didn't have affordable managed L3 nor L2 switches back then), and the server didn't even flinch. I think that we peaked at something like 1.4 Gbps on the ZFS striped pool, and a peak of 2% CPU usage on the pair of Socket940 AMD Opteron 254 CPUs that was in the system. So yeah, that turned out to be massive overkill, but oh well.
It's a temp setup for a 2-day event lol, not a full deployment. Besides, with Unifi sponsoring I'm sure they had cold spares on hand, it'd take like 3 minutes to swap a switch. If they were extra cautious, they may have even had a fully configured spare core switch.
@@AgencyNighthawk iirc They were talking about how they had spare hardware back at the office too, so in case their cold spares weren't enough, they'd also be able to go grab that quickly XD
I think its good that you posted this video. You're just doing your thing. Its the histrionic haters that are trying to capitalize on the situation, that I don't like.
People need to Grow up about the LMG "Issiue". The other issiue with ex employees is an internal matter, that unfortunately happens at every work place. It will be dealt with internally and allow people to have some kind of privacy as whatever comes out of it Im sure you wont be privy to personal outcomes unless either someone breaks NDA's to discuss or becomes slanderous.
There are issues with LMG and they need to be fixed. However, that doesn't mean that they are beyond redemption and that the company and especially the individual employees are persona non grata. The video is fine, adressing that there is an issue is fine. Not everything has to revoöve around certain issues and not everything needs to devolve into drama (though linus managed to do that just fine with his post and his half arsed apology segment in the response video).
Leave the LMG shit to the courts, none of us know the facts. I do know that everybody lies sometime, so that makes it hard for outsiders to know the truth. Do not participate in cancel culture.
@markbooth3066 agree but there are people trying too hard and posting negatively about LMG on every single publication that is even remotely link to LMG. I wish we can give them the opportunity to correct and straight up things. We should be cautious but supportive as long as they are addressing this issues.
I already went to their videos and tagged you, so no sense in repeatedly deleting my comment when you can just admit you were wrong@@CrosstalkSolutions
The fact they won't say who helped because they are on probation shows the type of toxic company LTT/LMG is. They put in the work, they did the job; give them the credit.
@@miguelchristopher7234 I didn't say it was illegal. I don't know US labor laws (IANAL). I especially don't know maple syrup labour laws. I do know what is toxic and LTT and LMG have really gone down that path pretty far.
Linus made a mistake? Yes (the biggest it’s to be sometimes stubborn). But the mob likes to points finger like they are perfect. This cancel culture is so bad. Linus has a big quality he show to everyone how he really is, for good and bad. People pretend to be good. He is very opened about his business like no one else, trying to improving every step. and be burned by this. Give the guy a break.
Too many folks complain about accountability as “cancel culture”, the reality is that if people took accountability they would be forgiven. The response to fight is what makes things worse. I am glad Chris is leaving the vid up but I can look at the network from a perspective detached from the LTT allegations.
@@8-n-125 The video title says 200Gbps network, which is misleading. A 200Gbps network has 200Gbps links and this only had 100Gbps links. Aggregating links does not make it a 200Gbps network as any single connection can never go faster than 100Gbps. I don't call my 200Gbps network at work a 400Gbps network because I have bonds of the 200Gbps. I expect better from a channel that is networking orientated.
@@jonathanbuzzard1376 What are you even talking about right now? You can definitely achieve 200Gbps throughput using LACP with two 100Gbps connections as well as 400Gbps with two 200Gbps. 100Gbps connections are technically already doing this with four internal 25Gbps channels. It's just not exposed to you in the interface. 200Gbps connections are 4x50Gbps channels. I think you're getting worked up over the wrong things here.
@@8-n-125 No the maximum speed that you can achieve between any two endpoints using LACP is the speed of a single link. If I get two hosts plug them into the same switch twice setup a bond for each host and then try and transfer files between them you will only get the speed of a single link. That the likes of 40Gbps are internally 4x10Gbps and 100Gbps is 4x25Gbps is utterly irrelevant to this as it is hidden below layer two. If you don't understand this limitation of LACP then you don't have the foggiest clue about networking frankly and you need to shut up before you embarrass yourself further. If you want to get more than the speed of a single link with a "bond" then you need multiple single links and use Multipath TCP. That however requires support from the OS and software stack to work and is not widely supported yet. As such that is *NOT* a 200Gbps network and the title is dishonest clickbait.
@@jonathanbuzzard1376 Throughput is not limited to measuring a single connection. This network was distributing 200Gbps of aggregate bandwidth from the firewall, to the core, to the 2.5Gbps and 10Gbps client switches. "If you want to get more than the speed of a single link with a "bond" then you need multiple single links and use Multipath TCP. That however requires support from the OS and software stack to work and is not widely supported yet." You are literally describing how this content was delivered to you through aggregate web services, load balancers, and regional caching servers. You're consuming content utilizing the "not widely supported yet" process. Please, before you engage in such aruguments and use disrespectful language to attempt to disparage others in discourse -- try to consider your personal perspective and how there might be a different one. Personally, I push far more than 400Gbps of throughput through aggregate links professionally. When you pay an ISP for aggregate traffic through an LACP bonded 800Gbps connection -- it's based (usually) on the 95% for *throughput* for that full 800Gbps not two 400Gbps connections.
WHYYYY? Is the very mention of LMG or LTT just taboo now? I think people need to honestly calm TF down now. Boycott them all you want but with everyone being this sensitive, it's getting a bit much now.
Linus knows whatever he did was wrong no need to beat the man while he down. Remember he’s no better than any of us, we all make mistakes. Own up move forward

It's a temp setup for a 2-day event lol, not a full deployment. Besides, with Unifi sponsoring I'm sure they had cold spares on hand, it'd take like 3 minutes to swap a switch. If they were extra cautious, they may have even had a fully configured spare core switch.
@@AgencyNighthawk iirc They were talking about how they had spare hardware back at the office too, so in case their cold spares weren't enough, they'd also be able to go grab that quickly XD
Leave it. Nothing here has anything to do with the drama and you shouldn't let the vocal minority dictate what you do anyways. :)
I think its good that you posted this video. You're just doing your thing. Its the histrionic haters that are trying to capitalize on the situation, that I don't like.
why doe every one just want to jump in steves drama, cant crfeators just make there owm content
❤❤❤❤❤
People need to Grow up about the LMG "Issiue". The other issiue with ex employees is an internal matter, that unfortunately happens at every work place. It will be dealt with internally and allow people to have some kind of privacy as whatever comes out of it Im sure you wont be privy to personal outcomes unless either someone breaks NDA's to discuss or becomes slanderous.
Grow up about sexual harassment not being taken seriously? Get fucked.
TOTALY AWSOME!!!! REALLY !!! RESPECT LTX and thnx ceosstalk for this video!
There are issues with LMG and they need to be fixed. However, that doesn't mean that they are beyond redemption and that the company and especially the individual employees are persona non grata.
The video is fine, adressing that there is an issue is fine. Not everything has to revoöve around certain issues and not everything needs to devolve into drama (though linus managed to do that just fine with his post and his half arsed apology segment in the response video).
Keep the video up. The video is about networking. If Jake becomes involved in the LMG issues then pull the vid or edit him out.
Leave the LMG shit to the courts, none of us know the facts. I do know that everybody lies sometime, so that makes it hard for outsiders to know the truth. Do not participate in cancel culture.
Lucky you got to go to the last LTX!
Two of my favorite channels. Good stuff!
No, f the cancel culture.
Nobody cancelled LMG, their corporate response was pure damage control, and entirely their own decision.
@markbooth3066 agree but there are people trying too hard and posting negatively about LMG on every single publication that is even remotely link to LMG. I wish we can give them the opportunity to correct and straight up things. We should be cautious but supportive as long as they are addressing this issues.

Incorrect.
So you're saying the Mikrotik incorrectly pronounces their own company name on their own videos?@@CrosstalkSolutions
I already went to their videos and tagged you, so no sense in repeatedly deleting my comment when you can just admit you were wrong@@CrosstalkSolutions

@@phenry5083 Needy much?
The fact they won't say who helped because they are on probation shows the type of toxic company LTT/LMG is. They put in the work, they did the job; give them the credit.
Came to say the same thing. Very belittling behavior, are you even really a person until you're hired at LTT?
@Archeious @technicalthug Canadian labour laws would like to speak to the both of you.
@@miguelchristopher7234 I didn't say it was illegal. I don't know US labor laws (IANAL). I especially don't know maple syrup labour laws. I do know what is toxic and LTT and LMG have really gone down that path pretty far.
@@miguelchristopher7234 Eff Trudeau and his stupid laws.
No, that's a fairly standard rule for Canadian companies.
It's actually done to protect the employee, not the company.
Keep the video, nothing to do with the drama.
Linus made a mistake? Yes (the biggest it’s to be sometimes stubborn). But the mob likes to points finger like they are perfect. This cancel culture is so bad.
Linus has a big quality he show to everyone how he really is, for good and bad. People pretend to be good.
He is very opened about his business like no one else, trying to improving every step. and be burned by this. Give the guy a break.
Too many folks complain about accountability as “cancel culture”, the reality is that if people took accountability they would be forgiven. The response to fight is what makes things worse. I am glad Chris is leaving the vid up but I can look at the network from a perspective detached from the LTT allegations.
Might not be the worst idea to delay this video until things become a bit more clear. Just a heads up. FWIW
No visitors of LTX or the technology have anything to do with drama.
Chris was wrong acknowledging it
@@jeffrydemeyer5433 Hard disagree, I think acknowledging it was the only way to run with this
Tech bros are incels, aka you op.
meh - it was mostly self promotion and we know how that went #cached copy of barbenheimmer #lan counseling session lock
Did.....did you just have a stroke?
Meh so no *actual* 200Gbps links, just bonded 100Gbps. Let me get back to work then with *actual* 200Gbps links.
It was a LAN party, mate XD
@@8-n-125 The video title says 200Gbps network, which is misleading. A 200Gbps network has 200Gbps links and this only had 100Gbps links. Aggregating links does not make it a 200Gbps network as any single connection can never go faster than 100Gbps. I don't call my 200Gbps network at work a 400Gbps network because I have bonds of the 200Gbps. I expect better from a channel that is networking orientated.
@@jonathanbuzzard1376 What are you even talking about right now? You can definitely achieve 200Gbps throughput using LACP with two 100Gbps connections as well as 400Gbps with two 200Gbps.
100Gbps connections are technically already doing this with four internal 25Gbps channels. It's just not exposed to you in the interface. 200Gbps connections are 4x50Gbps channels.
I think you're getting worked up over the wrong things here.
@@8-n-125 No the maximum speed that you can achieve between any two endpoints using LACP is the speed of a single link. If I get two hosts plug them into the same switch twice setup a bond for each host and then try and transfer files between them you will only get the speed of a single link. That the likes of 40Gbps are internally 4x10Gbps and 100Gbps is 4x25Gbps is utterly irrelevant to this as it is hidden below layer two. If you don't understand this limitation of LACP then you don't have the foggiest clue about networking frankly and you need to shut up before you embarrass yourself further. If you want to get more than the speed of a single link with a "bond" then you need multiple single links and use Multipath TCP. That however requires support from the OS and software stack to work and is not widely supported yet.
As such that is *NOT* a 200Gbps network and the title is dishonest clickbait.
@@jonathanbuzzard1376 Throughput is not limited to measuring a single connection.
This network was distributing 200Gbps of aggregate bandwidth from the firewall, to the core, to the 2.5Gbps and 10Gbps client switches.
"If you want to get more than the speed of a single link with a "bond" then you need multiple single links and use Multipath TCP. That however requires support from the OS and software stack to work and is not widely supported yet."
You are literally describing how this content was delivered to you through aggregate web services, load balancers, and regional caching servers. You're consuming content utilizing the "not widely supported yet" process.
Please, before you engage in such aruguments and use disrespectful language to attempt to disparage others in discourse -- try to consider your personal perspective and how there might be a different one.
Personally, I push far more than 400Gbps of throughput through aggregate links professionally.
When you pay an ISP for aggregate traffic through an LACP bonded 800Gbps connection -- it's based (usually) on the 95% for *throughput* for that full 800Gbps not two 400Gbps connections.
Lol, Linus is a Joke. Can't trust this guy.
I was baffled how much Chris thinks highly of that dipshit.
read the room...
Real talk: Given the self-inflicted wounds that LMG has undergone, perhaps it might be worth postponing this video indefinitely?
Or at least avoid obviously cross branding the video with LMG through the thumbnail. Minimize that connection.
WHYYYY? Is the very mention of LMG or LTT just taboo now? I think people need to honestly calm TF down now. Boycott them all you want but with everyone being this sensitive, it's getting a bit much now.
I think acknowledging the issues like Chris did was enough
Linus knows whatever he did was wrong no need to beat the man while he down. Remember he’s no better than any of us, we all make mistakes. Own up move forward
real talk: some need to go and touch grass. this video has nothing to do with what is happening at this point
Chat is going to need to be off for this one and comments disabled. Yikes these LTT sexual harassment liking fainbois are crazy.
Read the room. Linus is toxic.
Way to capitalize on the LTT doom train to get views. That almost makes you worse that Linus himself.
What a stupid opinion to have
The thumbnail is pretty egregious.
That’s an awfully high horse you’ve got there.
@@cricketbatman think he borrowed it from GN, after he just fell of it.
