As others have mentioned, hiring a few actually competent tech workers and not just KZread personalities who like tech would make these jobs much easier, but then it wouldn't triple as an upgrade, BC tax depreciation benefits, and free content I guess... They can claim 30% of the cost for these upgrades a year through depreciation, so basically they don't need to pay much if any business taxes as long as the upgrades cost enough, and they get free content. Better still, the more expensive it is, and the less competent they are in setting it up, the more content they get out of it. And if it's jank enough, even more content when it brakes, and a documented excuse to do another upgrade and repeat the cycle

But to start with a clean sheet in the new building and instantly have a complete mess is just unforgivable. Big bundles of mostly loose network cables coming in through the side of the cabinet? check (should have been in a cable tray and entered through the cabinet roof) Vertical mounting profiles too far forward so switches are almost right up against the front door? check (fiber and thick copper cables have quite large bend radius' and the front door may impinge on that) Narrow server type cabinet instead of network cabinet? check (extra 3 or 4 inches each side = much much easier to route and tidy cables) Network gear and server in same cabinet? check (lots of reasons to seperate them out - except for a few top of rack switches in server cabinets)

Hey Linus and team, it's nice to see Eaton playing the grease the palms game with you. But keep in mind the following. What might be there end game. Free sponsering, direct control of the most critical aspect of your infrastructure. It might be a good thing to occasionally look at how others do stuff. Just to be sure you don't get stuck on one thing.

It's really fun watching this particular video when I work for a major Data Center operator.

Good to see Linus actually knows what's going on and how all his hardware works. It really makes a difference when the people in charge understand the technology too.

Just deployed ceph myself, and other than performance being a bit difficult to achieve(but a fun challenge), it's basically been a distributed ZFS to run so far, highly recommend it, just make sure it's aware of your rack/building layout so data is distributed across failure domains and you don't have two copies in the same blade chassis!

I know you will never read this, Linus. But seeing where you came from and what you have done with your business, is just unreal to fathom to someone like me.

They went downhill since their move from the ltt house. It was such an interesting and innovative channel then. Nowadays it's just another dumbed down tech review channel, like literally dozens or hundreds on youtube. I wish they went back to the style of content they had 5-8 years ago.

Daisy chained switches, while not ideal, can be made to work if you at least loop it back in on itself and allow spanning tree to block on one of the ports. The fact that this was done in the first place does indicate a possible lack of understanding of the spanning tree protocol (STP), as well as the hierarchical design. Might I suggest starting with the Cisco CCNA 200-301 premium eBook! Also, make sure you have STP enabled, and preferable rapid spanning tree, to help reduce convergence times. And if you have the ability to configure it on the root bridge, make sure the main switch is a priority of 0, or at least lower than the default 32768, so that your downstream switches don't become the root bridge. And consider adjusting your hello timers from 2 seconds to 1 second, etc. Otherwise, looks amazing!

I have absolutely no idea what are you guys talking about but awesome!

adding a doorknob and weather stripping to the door to improve the seal between rooms will have 100x more impact on sound isolation than installing panels on the wall

I think you should consider some sort of physical security for those patch panels. even if it's an enclosure.

Here's a tech tip for ya: If you leave an air gap between materials, you'll get better sound isolation; you won't have sound transferring through the wall as much if there's an air gap.

Love it. Also great to see some large rollouts of U6 Enterprise. I have 130 rolled out at once campus, great wireless coverage!

I would recommend using STP or variant for the core networking switches. That way if there is a port failure your networking device can take a different path instead of having all the connections drop.

As an Enterprise/Infrastructure architect.. who loves Linus Tech tips PC builds.. don't do what they do.. High availability (HA) using Link aggregation and port channels. Building a core business system with no HA even for a small business makes it completely clear how they had a devastating outage recently and lost a lot of their data. Also nothing on their backups as of yet.. be interested to see how they are addressing that with 2PB of storage to deal with.

I'm happy to adopt these sad little server bays along with their content if you don't like them...

Good stuff LTT, love the infrastructure update videos

That Eaton 9pxm is insane, would love to have those at all the country schools with power issues, theyre sooo much lighter than the older lead acid ones my gosh so light and so much longer lifetime on the batteries drives me nuts when people buy the lead acid ones when lithium ion is available 😂

Anything behind the scenes is like the most interesting thing you guys do tbh it is definitely my favorite type of content

One of my top comments on a LTT video was about how bad their cable management was in one of their videos. It still ain't perfect but at the very least they've made a considerable effort to tidy it up. Well done!

Wow! I so would love to see a dedicated video on that high-availability server! (the 2u, 4 server box) That is sick. And I am so wondering how failover works between cpu and cpu, ram and ram, and how they stay in sync efficiently.

That's not how it works. Storage can be made highly available via various methods including the ones they mentioned (Ceph etc). There's no redundancy or interaction between the servers in terms of sharing CPU and RAM. They are independent machines, and if one blows up then whatever was running on it will have to restart on another machine. If the storage is still available via the other nodes then that's just the case of rebooting a VM (or whatever they're running), which is still much faster than replacing a physical machine.

As someone that's been doing networking for 15 years professionally and holds several industry recognized certs, you're getting better with the network stuff. I can't count how many videos I've watched where networking is involved, like VLANs and how much you guys struggle to do basic networking. I get you're a small shop, but the benefit of having an actual architect and engineer available to you for the projects where networking is critical, would save y'all a TON of headaches. I cringe anytime networking is involved, cuz y'all are gamers and systems guys. But the one thing that is central to all of the cool stuff you deploy is the network and you've put the least amount of effort in needed to get where you need to be. Hate to be harsh, but it's the truth. I doubt this comment will be seen, but there's WAY better ways to do stuff than you piecemealing your network together. Just my .02 cents worth.

Switched PDUs are amazing in a lights-out data center and agreed, 208 is the way to go for efficiency and density. Thanks for the Infra update. Speaking of servers, has LTT thought of doing a video on cloud computing, going over the main players. Oracle OCI, Amazon AWS, Google Cloud and Microsoft Azure. Talk about the strengths and weaknesses of cloud computing vs bare metal. And how one can get started in experimenting with cloud computing.

@calebkz

Жыл бұрын

Bare metal = you own the content and are solely responsible for storage. The main talking points of cloud are: scalability, built-in redundancy and a 3rd party to defer liability to. Linus has outlined his "anti-cloud" stance several times. It's also important to note the servers are for the employee and internal functions of what we see, we are watching on a cloud-based platform called you-tube. All of LTT sites and services are 'cloud' based in the sense that they are hosted off-prem. Experimentation is easy, Amazon AWS has free tiers to try stuff out.

There's no way you'd want to publish that type of information, there would be bad actors keen to knock out LTT. To be honest though, it would be a push over, there's no way they have got good controls at this point, Luke only just started.

First off we need some cable management across the rack - panduit makes some good stuff. By doing this you are able to remove and upgrade hardware easily since the wires are not in the way of removing the equipment. Next I would try to utilize servers that are identical as much as possible this allows stock piling of spare parts such as power supplies, drives, fans. Lastly use larger racks this allows more space for cable along the sides and room for server cable management arms and power cord routing. Also a keyboard management tray in the middle of the rack with kvm to all servers makes it fast and easy for any management that needs to be done locally.

Just put mine together last night. I wish I’d watched your video first as I spent longer than I’d like to admit looking for that bracket on the back of the handle. I had my kids helping me and yelling at them because I thought they may have thrown it out. lol. Did you ever replace the fan and if so white one did you use?

At this scale, I think it would serve your well to have a backup generator instead of chaining UPS

Probably due to noise, but UPS with fail-over generator would generally be the route most would take. Battery systems have gotten substantially cheaper over the last few years though, so if can guarantee that power will come back within a few hours, the maintenance etc. often makes it worth going that route instead. Generator of course if heavy machinery.

It’s been a while since we saw a server video for the office. Does this mean that the home server will also be upgraded?

Was very surprised (pleasently) to see a Mikrotik router. I usually work with CCR1009 and RB3011 and i love them!

It’s always fun to see these types of videos because I make many different types of cables and panels for my job. 😅

I appreciate that you show how cable management looks like in real life prod environment. I've been in companies that either demand unrealistic hyper clean cable management even for temp installments to ones that just dgaf and use a giant gordian knot of cables and tell you "you'll figure it out".

Same here, except I don't have a server room, but could definitely use one. I have a handful of VMs, lots of backups scattered on hard drives and USB drives that could definitely live on a NAS instead, and I also need a Tailscale exit node and subnet router (which is currently accomplished by a mini PC in my bedroom drawer), but zero cash to actually make it real. I'll also need a couple of web servers soon... yay

Are you guys using a UDM for the new location or a different management router/switch for that site? I havenn't had a good time using the UDM-Pro at our workplace and am getting it replaced with something not Unifi (Still keeping unifi infrustructure though)
