It's also great for businesses that want to test run a software before committing the full price, companies will do everything possible to stick to "if it ain't broken don't fix it", even when it means having to deal with extremely outdated and annoying (but technically functional) software, but if they can test it for free before spending big bucks to upgrade, they are more likely to do it.

I've been running an HA cluster at home for a year or two now. The downside is Proxmox doesn't understand "Hey! We have a power outage and there's only 5 minutes left of the UPS." It really doesn't shut down nicely---the cluster will keep migrating VMs as you try to do clean power-off in the dark. For server-down maintenance, it's fantastic though.
Yes, because other than stated in this video, the purpose of this tech is not to help you with hardware failures, it's for load balancing. Won't do shit to keep your system running. It's useless for most people, who do not run a datacenter.
NUT is your best friend, i have it running on a PI hooked to a UPS, when it looses power it monitors runtime, if it gets too low, SAFE shutdown all VM's and then host.
0:01 That chair needs to be replaced before it sheds all over the office. Faux leather gets EVERYWHERE when it starts flaking off and once it starts flaking, it accelerates fast.
This was my senior thesis for university! I designed a distributed fault coincidence avoidance solution using Proxmox VE with DRBD as VM backing storage. It bounced the virtual machine across the machine cluster randomly to reduce the odds of a fault coinciding with the critical process. It technically outperforms VSphere FT (But is not technically a full tolerance solution so it's not necessarily comparable.)
That's so cool. Can I get the link to your paper or your LinkedIn? Lmao this seems so random, but I am also a graduate searching for good thesis topics to study.
The thing about docker containers that can resolve the issue that Jake mentioned: A: run a Virtual Machine just to host these docker containers and the that VM will migrate around the hosts as needed. B: run that container in Kubernetes. Then you can configure load balancing, scaling and other cool features.
Came here to make the Kubernetes comment. If you run everything in containers, you get all this shit for free with very little effort, especially if you run managed k8s like Rancher or one of the cloud managed k8s services.
I just wanted to comment to say that Jake you’re looking good, my dude! You mentioned before about losing weight and it’s clear you’ve lost some more :) keep up the amazing work!
I think yayIHaveAUserName mentioned this in the disussion forum you linked, but unplugging your server and having whatever VMs are on there going down actually means that those VMs have to be rebooted on other servers. So technically...those VMs are failing, they're just being rebooted automatically. This matters if you're running a program that does not save state before it crashes because you might lose all your progress. It might also matter because you could mess up your filesystem if there were important write operations happening at the time of the crash. Very cool technology, but the video title is not 100% achieved, in my opinion. Also, the clustering section goes really quickly over fault-tolerance (i.e. "quorum"), but I don't feel like it was very well motivated other than just saying having two computers is not safe. Unless I misunderstood, the piece that seems like its missing is that this clustering program seems to be trying to handle Byzantine fault tolerance, where a computer could have a malicious user giving false data, which although is out of scope with your video, is the reason 2 computers with one fault is not safe for knowing what is the current, valid state of the system. Otherwise, why not trust the other computer to have the correct data? Simple redundancy would let you trust the one working computer with the source of truth.
Three things: 1) I'm already running this at home with three OASLOA Mini PCs (which sports an Intel N95 processor (4-core/4-thread)) in each node, along with 16 GB of RAM, and a 512 NVMe SSD. The system itself has dual GbE NICs, so I was able to use one of them for the clustering backend, and then present the other interface as the front end. (Each node, at the time, was only like $154.) 2) My 3-node Proxmox HA cluster was actually set up in December 2023, specifically with Windows AD DC, DNS, and Pi-Hole in mind, but then ended up changing to AdGuard Home, after getting lots of DNS overlimit warnings/errors. (Sidebar: I just migrated my Ubuntu VM from one node to another over GbE. It had to move/copy 10.8 GiB of RAM over, so that took the most time. Downtime was in the sub-300ms range. Total time was about 160 seconds.) 3) 100 Gbps isn't *that* expensive anymore. The most expensive part will likely be the switch, if you're using a switch. (There are lower cost switches, in terms of absolute price, but if you can and are willing to spend quite a bit more, you can end up with a much bigger switch where you'd be able to put a LOT more systems on 100 Gbps network vs. getting a cheaper switch, but with fewer number of ports overall. I run a 36-port 100 Gbps Infiniband switch in my basement. I have, I think, either 6 or 7 systems hooked up to it right now, but I can hook up to 29-30 more, if I need to.) On a $/Gbps basis, 100 Gbps ends up being cheaper, overall.
Having spent as much time as I have in my career troubleshooting DRBD issues, getting calls in the middle of the night about dreaded split brain, etc. I would gladly trade some level of performance in order to not use DRBD. Realistically you should have a cluster for storage and a cluster for compute, and therefore not have to worry about using something like DRBD to keep things in sync. With that being said, it's nice to finally see LMG moving closer to enterprise level infrastructure!
I was tasked with setting up a redundant storage cluster for an existing vm computer cluster. Literally got stuck for months back and forth with drbd support trying to get it working. They have a small team amd their support is good. But I seemingly managed to stumble over every bug and problem with their software just setting it up. Gave up in the end and decided to try with Microsoft hypervisor...
Good for two virtual desktops basically doing nothing. I wonder if there was a couple of hundred task worker / devs or heavy users doing there things. Not so sure.
@@glaucorodrigues6400 in reality, those couple of hundred Devs would be spread across the Hypervisor hosts already, so you'd only get "up-to" 2 minutes of disruption on 1/4th, 1/5th etc of them (depending how many hypervisor hosts you have, probably a lot more than 4 for a couple hundred heavy users)
Yeah that kinda made me laugh - "We made a thing that can migrate VMs real fast... But we wait 2 minutes to do it"... Kinda undermines the whole point of the system...
@@glaucorodrigues6400 If you have a couple hundred task workers on 4 machines... you are already expecting to have a bad day. While VM's are voodoo... thin provision at your own risk I guess.
From experience 1) that is not enough RAM, I'd recommend at least twice as much. If you have memory heavy workloads, I'd recommend even more. 2) You should really use a dedicated NIC for management and coro sync. 3) If you use network storage, you want jumbo frames and therefore a dedicated network. 4) if you have heavy guest traffic, you should definitely use a dedicated NIC for that as well.
It's funny to watch LTT slowly work through the last 50 years of server & DC innovation, as they grow and run into every issue that originally spawned those innovations to begin with. Eventually they might actually arrive in the present best practices.
The weird thing the most times on LTT nearly every video there is a windows machine that is in the blue upgrading screen when you actually want to use it. I think this is a bigger problem especially with the recent crowd strike failure taking out the worlds computers.
@@colinstu In a modern server system you typically have not just redundant hardware or the ability to migrate or restart a single VM, since that only protects you against failure of the hardware. What you do instead, is to have multiple instances of the same software running across multiple hardware. In comparison to this VM based redundancy that additionally protects you from random failures in OS, libraries or the application code, which VM migration does nothing against. Additionally it also unlocks the potential for scale out autoscaling, and zero downtime upgrade strategies. On a single VM your best option for upgrades is to do a snapshot to return to, but the application will still be down for the length of the update. When you have multiple instances of the software however, you can upgrade them at different times preserving overall availability, only update a few and check on feedback first (canary deployment), etc. Of course details vary a bit depending on how your software works exactly.
@@autarchprinceps You know you could've said "clustering" or "CARP" in the first post and avoid all this pussyfooting around. Yeah no crap. That also involves at least 3x the hardware (usually can't just cluster between two machines). I don't see them spending that kind of money, especially not for a goofy media company.
A video sponsored by intel about a PC that can't fail with its current reliability issues is so funny. I know these deals are sometimes a long process but wow intel did not gain much out of this particular video's sponsorship.
I know LTT has never been very 'enterprise-y', but I find it hilarious that the example 'perfect use case' of a hyper-converged HA cluster of hosts is DNS and Active Directory DCs. Some of the most fault-tolerant systems, which are specifically designed in a way for multiple VMs to be used.
Yeah, I wouldn't even necessarily include the DCs in the failover. Leaves more resources for other VMs. Just make sure you have enough of them and don't have them running on the same node. Linus seemed so excited for AD, I wonder why they did not implement it yet. It's not that hard compared to other stuff they did
@@timcappell71 He had said it in some video, but I don't quite remember it right, but I think it was due to not having a dedicated IT team to manged it. Of course, they can manged it themselves, but it would take time from other stuff.
@@michaelkreitzer1369no need to. Have a VRRP/keepalived IP in front of multiple servers. DNS is literally the worst possible example. It has good caching and replication built in, with it being (mostly) UDP you won’t even have a TCP stream disrupted if it changes machines during a failover. It’s the one thing that just works in a replicated fashion. (Also I guess AD also offers some HA replicated setup…)
Very cool tech. I’ve used HA (High Availability - this tech in the VMWare world) for years and it’s amazing. Even more amazing is FT (Fault Tolerance) where a complete mirror VM is already running on a second host and no “migrating” occurs. Packets just redirect and it’s very magical. Shared storage is usually involved though, so this storage sync method is very cool if you don’t have shared storage. One nitpick though. Your thumbnail implied this would help with blue screens, but any issue at the software/OS level would not be prevented with this setup at all. If you add watchdog tools to reboot or migrate a VM if a heartbeat is lost, that’s completely different than the host becoming unavailable from a hardware issue and doesn’t need this “fancy” of a setup to just address a software glitch. If this setup has a heartbeat watchdog feature, I don’t see it mentioned here, but again, software glitches like a blue screen are an entirely different problem with entirely different solutions than hardware failures.
I was already planning a very expensive upgrade to my home lab that will take a while to save up for and you show me this really cool stuff that I would also love to do. Please stop.
"beginners should start with Ceph" said no one ever. Ceph has gotten easier to setup and maintain over the years, but that doesn't make it less of a complex distributed application with surprisingly strict requirements on certain aspects of the setup like network stability. It's easy to get it to e.g. dead lock all your vms because mons failed over due to some packetloss in an overloaded switch. Been there, debugged that.
Having run some large Ceph clusters (multi PB), I usually find as long as the network is stable, and performant enough, Ceph is rock solid. Proxmox does a great job of deploying Ceph for you. DRDB on the other hand, I ran out of performance pretty quickly on some database servers.
I've had a three node CEPH cluster at home for about 9 years. My only Linux experience before that was using ZFS for a file server. I've never used Proxmox or 45Drives' Houston UI, but it seems like they make CEPH a lot simpler. Just don't expect very many IOPS out of CEPH.
Before everyone’s like “sponsored by Intel on a reliability video”, this isn’t blonde Linus, this was probably filmed like 30 years ago As for that unplugging PC bit, one of my old teammates was part of Live Migration in AWS, which is that “carry over an instance from server to server without noticing a difference”

I have a Proxmox cluster at home that runs off of 3 mini PCs: AMD Ryzen 7 5800Us, 32GB of RAM, 2.5GB ethernet, and shared storage via NFS on my NAS. Those mini PCs give me 48 vCores and 96GB of RAM in my cluster, which is plenty for my home lab. Also was relatively cheap, got those all running for about $1000 (NAS not included, would be about $1000 more for my RAID1 36TB NAS). Also because the Ryzen 7 5800Us are laptop chips, this thing sips power and has great efficiency.
@@BoraHorzaGobuchul it looks like if I mention any links or brands I get deleted, but if you search "5800u mini PC dual LAN" you'll likely find something very similar to what I have.
I have a somewhat mini version of this hardware in a way with two laptops of Ryzen PRO 2300U, 8 GB RAM, 512 GB drive, plus a NAS with 20 TB usable (1 Gbps network tho). I'm now considering getting a third of such a laptop and configuring it into a cluster too... (currently only one of them has Proxmox and the other just Debian) But not sure if it's worth it with such cheap machines, plus they could use some RAM upgrade perhaps. But hey, at least they were cheap (~50$) and have built-in battery backup...
I have the same but with 4 intel N100's half the price, 1/4 the power usage, but also 1/4 the performance. But still, it's plenty to run everything I need. however, I'm gonna look at those ryzen 9000 series laptop chips.
This is great, your PC blue-screens and proxmox moves the VM to another server where it will continue to blue-screen. It's perfect. VMware have had this functionality for a decade, they even have HA VMs where the memory is constantly synced giving an instant failover that is several hundred times faster.
Yeah, most of the time a BSOD has got nothing to do with hardware failure an thus this entire stupidly expensive sponsor/PR-money video is useless as a method of avoiding bluescreens.
I mean I've known about live migration for years and it still impresses me :P It's particularly cool seeing it done open source with custom HCI nodes, I am curious why they didn't go with OpenStack though.
@@almc8445 IIRC they have experience with Proxmox VE. Also Proxmox seems way easier to manage on this small scale, while still providing all necessary features.
2004 actually, so 20 by now. But yes, what I thought as well. It has come as far as being removed or at least deprecated by many newer DC/Hypervisors/-scalers in one way or another, as it's main flaw is, that it only protects you against things failing below the VM level. If the OS or the App fails, you're still just as screwed. A more modern design, e.g. putting DNS in multiple autoscaling containers or even just VMs on similar hardware cluster, would also allow you to 1. have a failure in any level of application or below, 2. scale and distribute load with demand, and 3. if you do it right, even allow you to be protected against failure do to changes/updates, as you can do various forms of rolling, blue green, or more complex etc. deployments, and still have both older and newer version available to fall back to. With a single VM with live migration, you only option then would be to restore to a snapshot, assuming you have one recent enough. Still causes downtime and potentially significant data loss though, which a modern system wouldn't need to risk. That's also why the container doesn't have live migration capability unlike the VM in their example as well. It assumes you have moved beyond that, if you have implemented containers into your architecture. Nothing theoretically preventing you from implementing the same things on a container level, just nobody cares anymore. Also more resource hungry to implement, as you need constant memory duplication synchronised with I/O activity, if you really want it to work for failure and not just planned migrations. It wouldn't work seamlessly if your memory was restored to a state before you send a network or disk request after all, as it would cause potentially catastrophic inconsistencies.
@@almc8445 why would they prefer OpenStack? Proxmox is much more integrated and easier to learn/understand. OpenStack might have been a good option if they were doing this for clients.
13:29 are you telling me LMG has been around for as long as it has, with as many employees as it has, with as many severs as it has... and you haven't been using AD up to this point...?
Dude, I was just about to ask the same question. And aswell, they just NOW started a virtualisation Cluster, huuuuh? I work in it consulting and at a certain size, everyone of our customers has a virtualisation cluster.
At a certain scale it's not worth the overhead/cost and if I'm being honest, if you have a Greenfield estate I would just bang everyone on azure directory and side step on-prem AD. Current company is around 800 users with a decent chunk of infra and no AD in sight. Currently looking to implement it for a product as it will provide a better user experience to the workers if a certain bit of kit.

For my work, the production environment runs on Solaris clusters for HA. It was interesting to the differences between the configuration and management tools and interfaces.

I know you all have those big Eaton UPS systems there.

Probably RAM or Power supply. Check your reliability history to try diagnose what is causing it, it will tell you weather it was a hardware issue and give you some info that might help diagnose the source.

Fault tolerance in Cloud Computing is basically the same thing. We just use multiple servers which we don't own and have no physical access to. We rent them in a way which reduces the costs a lot. Seeing this being done on physical hardware was a great experience and a good demonstration of how it is done. Knowing the theory behind it and seeing it happen was fun. It is kind of uninteresting when you use an interface to do it and have no contact with the actual hardware. Gonna do this one day when I create my own server.
I build this setup with 10 year old servers, 1gbe between them and Proxmox and linstor a few years ago. This served the production traffic for a not so small professional webhosting scenario. It needed some finetuning but linstor works quite well with not so fast bandwith.

I've been running an HA cluster at home for a year or two now. The downside is Proxmox doesn't understand "Hey! We have a power outage and there's only 5 minutes left of the UPS."

It bounced the virtual machine across the machine cluster randomly to reduce the odds of a fault coinciding with the critical process.

I think yayIHaveAUserName mentioned this in the disussion forum you linked, but unplugging your server and having whatever VMs are on there going down actually means that those VMs have to be rebooted on other servers. So technically...those VMs are failing, they're just being rebooted automatically. This matters if you're running a program that does not save state before it crashes because you might lose all your progress. It might also matter because you could mess up your filesystem if there were important write operations happening at the time of the crash. Very cool technology, but the video title is not 100% achieved, in my opinion.
Also, the clustering section goes really quickly over fault-tolerance (i.e. "quorum"), but I don't feel like it was very well motivated other than just saying having two computers is not safe. Unless I misunderstood, the piece that seems like its missing is that this clustering program seems to be trying to handle Byzantine fault tolerance, where a computer could have a malicious user giving false data, which although is out of scope with your video, is the reason 2 computers with one fault is not safe for knowing what is the current, valid state of the system. Otherwise, why not trust the other computer to have the correct data? Simple redundancy would let you trust the one working computer with the source of truth.
Three things:
1) I'm already running this at home with three OASLOA Mini PCs (which sports an Intel N95 processor (4-core/4-thread)) in each node, along with 16 GB of RAM, and a 512 NVMe SSD. The system itself has dual GbE NICs, so I was able to use one of them for the clustering backend, and then present the other interface as the front end. (Each node, at the time, was only like $154.)
2) My 3-node Proxmox HA cluster was actually set up in December 2023, specifically with Windows AD DC, DNS, and Pi-Hole in mind, but then ended up changing to AdGuard Home, after getting lots of DNS overlimit warnings/errors.
(Sidebar: I just migrated my Ubuntu VM from one node to another over GbE. It had to move/copy 10.8 GiB of RAM over, so that took the most time. Downtime was in the sub-300ms range. Total time was about 160 seconds.)
3) 100 Gbps isn't *that* expensive anymore. The most expensive part will likely be the switch, if you're using a switch. (There are lower cost switches, in terms of absolute price, but if you can and are willing to spend quite a bit more, you can end up with a much bigger switch where you'd be able to put a LOT more systems on 100 Gbps network vs. getting a cheaper switch, but with fewer number of ports overall. I run a 36-port 100 Gbps Infiniband switch in my basement. I have, I think, either 6 or 7 systems hooked up to it right now, but I can hook up to 29-30 more, if I need to.) On a $/Gbps basis, 100 Gbps ends up being cheaper, overall.

Having spent as much time as I have in my career troubleshooting DRBD issues, getting calls in the middle of the night about dreaded split brain, etc. I would gladly trade some level of performance in order to not use DRBD.
Realistically you should have a cluster for storage and a cluster for compute, and therefore not have to worry about using something like DRBD to keep things in sync. With that being said, it's nice to finally see LMG moving closer to enterprise level infrastructure!

I was tasked with setting up a redundant storage cluster for an existing vm computer cluster.
Literally got stuck for months back and forth with drbd support trying to get it working. They have a small team amd their support is good. But I seemingly managed to stumble over every bug and problem with their software just setting it up. Gave up in the end and decided to try with Microsoft hypervisor...
16:45 - Yes. Proxmox VE's High Availability full failover window is hard-coded at 120 seconds.
Good for two virtual desktops basically doing nothing. I wonder if there was a couple of hundred task worker / devs or heavy users doing there things.
Not so sure.
@@glaucorodrigues6400 in reality, those couple of hundred Devs would be spread across the Hypervisor hosts already, so you'd only get "up-to" 2 minutes of disruption on 1/4th, 1/5th etc of them (depending how many hypervisor hosts you have, probably a lot more than 4 for a couple hundred heavy users)
Yeah that kinda made me laugh - "We made a thing that can migrate VMs real fast... But we wait 2 minutes to do it"... Kinda undermines the whole point of the system...

@@almc8445 maybe not optimal, but still faster than having a user go to IT, having them figure out why the server is down, and having them restart it
From experience
1) that is not enough RAM, I'd recommend at least twice as much. If you have memory heavy workloads, I'd recommend even more.
2) You should really use a dedicated NIC for management and coro sync.
3) If you use network storage, you want jumbo frames and therefore a dedicated network.
4) if you have heavy guest traffic, you should definitely use a dedicated NIC for that as well.
All of this is true.
It's funny to watch LTT slowly work through the last 50 years of server & DC innovation, as they grow and run into every issue that originally spawned those innovations to begin with. Eventually they might actually arrive in the present best practices.
Do anything, turn it into content
The weird thing the most times on LTT nearly every video there is a windows machine that is in the blue upgrading screen when you actually want to use it. I think this is a bigger problem especially with the recent crowd strike failure taking out the worlds computers.
and what's that? don't tell me it's some cloud bullshit
@@colinstu In a modern server system you typically have not just redundant hardware or the ability to migrate or restart a single VM, since that only protects you against failure of the hardware. What you do instead, is to have multiple instances of the same software running across multiple hardware. In comparison to this VM based redundancy that additionally protects you from random failures in OS, libraries or the application code, which VM migration does nothing against. Additionally it also unlocks the potential for scale out autoscaling, and zero downtime upgrade strategies. On a single VM your best option for upgrades is to do a snapshot to return to, but the application will still be down for the length of the update. When you have multiple instances of the software however, you can upgrade them at different times preserving overall availability, only update a few and check on feedback first (canary deployment), etc.
Of course details vary a bit depending on how your software works exactly.
@@autarchprinceps You know you could've said "clustering" or "CARP" in the first post and avoid all this pussyfooting around. Yeah no crap. That also involves at least 3x the hardware (usually can't just cluster between two machines). I don't see them spending that kind of money, especially not for a goofy media company.

I know LTT has never been very 'enterprise-y', but I find it hilarious that the example 'perfect use case' of a hyper-converged HA cluster of hosts is DNS and Active Directory DCs. Some of the most fault-tolerant systems, which are specifically designed in a way for multiple VMs to be used.
That's a pretty good point. However, it's surprisingly hard to get Linux or Windows to actually _use_ their secondary DNS servers!
Yeah, I wouldn't even necessarily include the DCs in the failover. Leaves more resources for other VMs. Just make sure you have enough of them and don't have them running on the same node. Linus seemed so excited for AD, I wonder why they did not implement it yet. It's not that hard compared to other stuff they did
@@timcappell71 He had said it in some video, but I don't quite remember it right, but I think it was due to not having a dedicated IT team to manged it. Of course, they can manged it themselves, but it would take time from other stuff.
@@michaelkreitzer1369no need to. Have a VRRP/keepalived IP in front of multiple servers. DNS is literally the worst possible example. It has good caching and replication built in, with it being (mostly) UDP you won’t even have a TCP stream disrupted if it changes machines during a failover. It’s the one thing that just works in a replicated fashion. (Also I guess AD also offers some HA replicated setup…)
@@tmbchwldt3508 Ya but these features are basically free. Once you have a N+# failover cluster it's more work to not apply it to all VM's.
Very cool tech. I’ve used HA (High Availability - this tech in the VMWare world) for years and it’s amazing. Even more amazing is FT (Fault Tolerance) where a complete mirror VM is already running on a second host and no “migrating” occurs. Packets just redirect and it’s very magical. Shared storage is usually involved though, so this storage sync method is very cool if you don’t have shared storage.
One nitpick though. Your thumbnail implied this would help with blue screens, but any issue at the software/OS level would not be prevented with this setup at all. If you add watchdog tools to reboot or migrate a VM if a heartbeat is lost, that’s completely different than the host becoming unavailable from a hardware issue and doesn’t need this “fancy” of a setup to just address a software glitch.
If this setup has a heartbeat watchdog feature, I don’t see it mentioned here, but again, software glitches like a blue screen are an entirely different problem with entirely different solutions than hardware failures.
I was already planning a very expensive upgrade to my home lab that will take a while to save up for and you show me this really cool stuff that I would also love to do. Please stop.
I love it when Jake is showing us more and more network/server functionality. I would love to see Jake host videos like these!
"beginners should start with Ceph" said no one ever. Ceph has gotten easier to setup and maintain over the years, but that doesn't make it less of a complex distributed application with surprisingly strict requirements on certain aspects of the setup like network stability. It's easy to get it to e.g. dead lock all your vms because mons failed over due to some packetloss in an overloaded switch. Been there, debugged that.
Sounds oof
Having run some large Ceph clusters (multi PB), I usually find as long as the network is stable, and performant enough, Ceph is rock solid. Proxmox does a great job of deploying Ceph for you. DRDB on the other hand, I ran out of performance pretty quickly on some database servers.
Oh yes. And the upgrades. And rebalances. Perfect software for a curious beginner
I've had a three node CEPH cluster at home for about 9 years. My only Linux experience before that was using ZFS for a file server. I've never used Proxmox or 45Drives' Houston UI, but it seems like they make CEPH a lot simpler. Just don't expect very many IOPS out of CEPH.
Why would they use old DRDB over the builtin ceph

I have a Proxmox cluster at home that runs off of 3 mini PCs: AMD Ryzen 7 5800Us, 32GB of RAM, 2.5GB ethernet, and shared storage via NFS on my NAS. Those mini PCs give me 48 vCores and 96GB of RAM in my cluster, which is plenty for my home lab. Also was relatively cheap, got those all running for about $1000 (NAS not included, would be about $1000 more for my RAID1 36TB NAS). Also because the Ryzen 7 5800Us are laptop chips, this thing sips power and has great efficiency.
Which minipcs did you use?
@@BoraHorzaGobuchul it looks like if I mention any links or brands I get deleted, but if you search "5800u mini PC dual LAN" you'll likely find something very similar to what I have.

I'm now considering getting a third of such a laptop and configuring it into a cluster too... (currently only one of them has Proxmox and the other just Debian) But not sure if it's worth it with such cheap machines, plus they could use some RAM upgrade perhaps. But hey, at least they were cheap (~50$) and have built-in battery backup...

You just made the project I have at work significantly easier, because you literally made a guide on how to do it. Thanks, guys!
This is great, your PC blue-screens and proxmox moves the VM to another server where it will continue to blue-screen. It's perfect.
VMware have had this functionality for a decade, they even have HA VMs where the memory is constantly synced giving an instant failover that is several hundred times faster.
Yeah, most of the time a BSOD has got nothing to do with hardware failure an thus this entire stupidly expensive sponsor/PR-money video is useless as a method of avoiding bluescreens.

@@almc8445 openstack always smelt like weird enterprise software - "better buy our mainframe with support license, if you want to properly use it..."
2004 actually, so 20 by now. But yes, what I thought as well. It has come as far as being removed or at least deprecated by many newer DC/Hypervisors/-scalers in one way or another, as it's main flaw is, that it only protects you against things failing below the VM level. If the OS or the App fails, you're still just as screwed. A more modern design, e.g. putting DNS in multiple autoscaling containers or even just VMs on similar hardware cluster, would also allow you to 1. have a failure in any level of application or below, 2. scale and distribute load with demand, and 3. if you do it right, even allow you to be protected against failure do to changes/updates, as you can do various forms of rolling, blue green, or more complex etc. deployments, and still have both older and newer version available to fall back to. With a single VM with live migration, you only option then would be to restore to a snapshot, assuming you have one recent enough. Still causes downtime and potentially significant data loss though, which a modern system wouldn't need to risk.
That's also why the container doesn't have live migration capability unlike the VM in their example as well. It assumes you have moved beyond that, if you have implemented containers into your architecture. Nothing theoretically preventing you from implementing the same things on a container level, just nobody cares anymore.
Also more resource hungry to implement, as you need constant memory duplication synchronised with I/O activity, if you really want it to work for failure and not just planned migrations. It wouldn't work seamlessly if your memory was restored to a state before you send a network or disk request after all, as it would cause potentially catastrophic inconsistencies.
@@almc8445 why would they prefer OpenStack? Proxmox is much more integrated and easier to learn/understand. OpenStack might have been a good option if they were doing this for clients.
13:29 are you telling me LMG has been around for as long as it has, with as many employees as it has, with as many severs as it has... and you haven't been using AD up to this point...?

My mind was damn blown too!
I'm not in context of Windows server ecosystem, why is AD desirable other than SSO?
At a certain scale it's not worth the overhead/cost and if I'm being honest, if you have a Greenfield estate I would just bang everyone on azure directory and side step on-prem AD.
Current company is around 800 users with a decent chunk of infra and no AD in sight. Currently looking to implement it for a product as it will provide a better user experience to the workers if a certain bit of kit.

For my work, the production environment runs on Solaris clusters for HA. It was interesting to the differences between the configuration and management tools and interfaces.

Probably RAM or Power supply. Check your reliability history to try diagnose what is causing it, it will tell you weather it was a hardware issue and give you some info that might help diagnose the source.
If on Windows:
In the search bar: Control panel
In control panel: go to security and maintenance -> reliability monitor
On top of the other recommendations, wipe your GPU driver and possibly chipset too. Both of those have caused BSODs for me in the past
0:10 i hope he eats you're lunch Linus
@@michaelgetty3602 I hope he eats you are lunch Linus
he obviously meant to say "i hope he eats; you're lunch, Linus"
Why is he lunch?
"Linus, I am going to eat you're... *Lunch* "
Lunch tech tips
What's stable today can become unstable tomorrow...
Thanks Intel 😂
can i use remote desktop for daily use in uni `via laptop in class , pc in hostel room?
Great video guys! Great to see Proxmox getting some love.
I love this! i am really enjoying toying with VMs and server infrastructure on my spare time. While I won't be able to deploy something like this atm from home. It was still very entertaining!
1:53 *Mutahar enters the chat*
"and you can too"
I can fail?
I mean yes, and we have a whole profession around trying to turn you off and on again when that happens.
Truly inspirational
I'm not going to lie, I winced when he shoved that pc off the table at 2:13
It probably fell onto a cushion, but yea same
I expected a video that was more to the tune of setting up a RAID array, installing ECC memory, downclocking and installing huge tower coolers without fans. But this works too I suppose :D
live migration is super cool, a while back I tried it on a small 2 host proxmox cluster and I was just AMAZED to see it migrate a VM from one host to another with only a few 100 ms of actual downtime
0:45 More Servers!

time to install cloudstrike too
$100K worth of equipment to be able to fail over a DNS server.
Or...
...you could have two $100 DNS servers.
jakes work and knowledge of corpo nets is quite impressive at this point.. they grow up so fast.
Good on Jake, he's looking good. Proud of your journey dude.
Had nothing but slow performance and trouble with those Patriot drives. Also considering the recent issues with Intel CPUS... that title is funny
They're perfectly fine as a hypervisor boot/os drive though.
Ah yes Intel, the company renowned for its reliability.
Sapphire Rapids is pretty reliable since it’s based on the old Alder Lake micro architecture, its performance is inferior to EPYC but it’s easier to get your hands on entry level XEON.
It was believed so for years!
Just more proof that nothing is forever
Oh.. the ironic one.
Seeing how linus is not yet blonde in the video, we know they unironicly made this.
No, this is him now, he just dyed his hair brown on top of the blond, you can see where he missed the blond on the back of his head. LOL
@@nicesmile3125 nah, they did a test spot on the back of his head before bleaching the rest. So this was maybe the day before he bleached the rest of it
I think it's very cool that I learned all of this in some college classes and literally got a degree for putting this kind of technology to use. I appreciate the refresher course Linus!
Running infrastructure management using virtualization on a server has a huge impact.
As a rule of thumb, any component that is a few years old is more-or-less absolutely reliable.
I've still got a system running on a Ryzen 1700; though that was solid when it released, let alone 5 or whatever-years on from now.
My unraid server is runing on a first gen i5 760 14 years old still going strong ha
It's not the age of the component, it's the run time. Some people will only notice the degradation in their years old Intel 14th gen CPUs in a few years if they only use it lightly and don't update their bios
New meme 17:34
18:48 - me when i look at my vape after not using it for 10 seconds.
Fault tolerance in Cloud Computing is basically the same thing. We just use multiple servers which we don't own and have no physical access to. We rent them in a way which reduces the costs a lot. Seeing this being done on physical hardware was a great experience and a good demonstration of how it is done. Knowing the theory behind it and seeing it happen was fun. It is kind of uninteresting when you use an interface to do it and have no contact with the actual hardware. Gonna do this one day when I create my own server.
I remember labbing up proxmox and ceph a few years ago. It sure has come a long way in a short time.
Wait 0:40 you have a boss.
he said before he was stepping down from ceo to have more time
LMG does not run Active Directory Domain Services with a company with 100+ employees!? How do they deem this acceptable?
Won't be Surprised if one of the employees at LMG has a bottle of Whiskey🥃 in his drawer

I build this setup with 10 year old servers, 1gbe between them and Proxmox and linstor a few years ago. This served the production traffic for a not so small professional webhosting scenario. It needed some finetuning but linstor works quite well with not so fast bandwith.
"Get your mind out of the description!!" LOL Awesome Video Guys!!
3:35 Funny how that 32 core CPU uses less power than Intel’s current lineup…
Filmed pre-bleaching, but post doing the patch of test bleaching.

"all at a modest 300W TDP"? Are you freaking kidding me? C'mon guys, yes it's more efficient then a bloody 14900KS, but this thing is designed to run 24/7, you can get much more efficient 32 Core Processors. Just not from Intel lol.
you say that, and then I look at my EPYC 7402P pulling 200W at idle 😭
@@insu_na This lmao. AMDs server CPUs were dog thrash early on. They're just now getting to the point where you could consider them for your next deployment. AMD is legendarily awful in the server space.
@@Pipsispite ehh, I think Milan and Genoa are already pretty good.
@@Pipsispite They've been undefeated in performance for many years now. Sure idle wattage may not be great but datacenters don't leave their hardware idle most of the time
@@Pipsispite So... if the EPYCs are so awful, then explain to me why AMD is gaining market share in the server space for years now?
Love the homelab focused content!!
Props on the dechubbification, Jake!
5:24 What is 6.9? A very good thing ruined by a period.
69 is overrated. It looks fun but it's hard enjoying it while you're concentrating on making it enjoyable for the other party. I find that doing those in sequence as opposed to in parallel is much preferable
0:02 Simgot EW200!?
yeah it seems , wonder what dac he use
That’s a crazy notice! Great value too!
Ironic that Intel sponsors a video about a computer that can't fail. Fix your CPUs first.
Just wanted to say I love the way Jake describes stuff. I have almost no idea about any of this stuff, but listening to Jake talk about it, I just kind of 'get the idea' enough to follow along. Sometimes hearing people talk about super technical stuff outside of my sphere, I get extremely lost very quickly.
Not saying I understood everything, but I understood *enough* to follow along with the video. Y'know?
I watched, delete
