"Don't offer $50 below asking." Dude, you asking $500, i'm going to offer $350, you counter with what your bottom dollar is. If you get offended, hey, i'll take my money elsewhere. If you select the option to accept offers, you better be prepared for that.

“Nobody would be crazy enough to have one of these in their homeland” Me with 2 of these, and 3 of the 2 node variant 😂 (all running Nutanix AHV of course, so Ping me if you need any help getting Nutanix working) Also, you got sent the wrong rails entirely. These 4 node chassis are intended to use a rail set nearly identical to your l brackets as the chassis is intended to be installed, and not slide in and out, just slide out the nodes

U crazy ;) I was considering similar old server HW, but maybe I just enjoy your suffering while buying new regular HW instead.

I used to run fat stacks of Xeons in my lab, but I've been replacing them with single socket AMD Epyc systems, and in some cases mini PCs, because newer CPU architectures are dramatically faster and more power efficient than old Xeons, and having only one socket means far fewer SMP/NUMA speedbumps. And the noise... just one of my old Xeon Supermicros, even with the optimized fan setting, is louder than my other 5 nodes and all the switches combined. I don't wanna go back to the jet engines.

It sounds like you have reservations about Hyper-V, but Hyper-V does have an interesting advantage when using a quad node system like you have. As far as I'm aware VMware, Proxmox, and Nutanix all need a minimum of 5 nodes if you want the cluster to be able to take any two storage failures (Such as a failed disk, a failed host, or even a host being rebooted). VMware for example will make 3 copies of the VM and place them on 3 different hosts and then a "witness" component on 2 more hosts (A small files used to vote for control of the VM). This way if the cluster is split and say 3 nodes can talk to each other, but not the other 2, they can use the fact they own 3 of 5 parts of each VM to know they can safely bring up the VM's and the other two nodes are not elsewhere doing the same. It probably sounds a bit complicated in a 5-node setup, but in a larger setup when a split cluster could have whole VM's it each half, it allows each half to operate independently starting only the VM's they have majority control over. Hyper-V handles this a bit differently by electing a master node based on a cluster vote and that node decides who can run what. If the master node fails, the remaining 3 of 4 nodes will vote to elect a new one. The tricky bit is the 2nd failure. If 2 nodes fail, the remaining two nodes have no way to know if failed nodes are actually offline or if they just lost communication with them. In this situation 2 of 4 nodes can't obtain a majority vote to run the cluster, as that would allow a 2-2 split cluster to each start a copy of all the VM's. To avoid this, we need a 5th vote. Rather than a 5th node, which is kind of a pain when running with a quad node chassis, Hyper-V can use an external witness. VMware has an external witness as well, but in their case the witness is a whole VM that has to be ran off cluster. Hyper-V just needs an SMB2 compliant share the hosts can read and write to. In face the requirements are so low that in Microsoft's own documentation, they advise even a flash drive shares out from a SOHO router is enough. No need to worry about router reboots as well, as this share is only needed when there are not more than 50% of the cluster hosts available. I'm not 100% sure about Proxmox/Ceph yet, but both VMware and Nutanix are limited to one host fault at 4 nodes. This is likely fine for a homelab, but I run clusters at work and home and it's something to keep in mind.

maybe cloudstack apache?

cluster PLEX. would love to see the scalability. just not sure that those cpus have Intel QS

I know it's bin a while now but is there and update part list if you were to build a new pc with what is available now?

Thanks. Just bought this for this very purpose- a cruise. But why not make a video showing step by step just how one would use this on a cruise as if you were on that cruise? A video that my mom could follow. This was waaaaay too technical for anyone not familiar with routers.

Wow awesome new server! I'd love to see you try RedHat OpenShift virtualization + RH Data Foundation (k8s + KubeVirt + Ceph). Installing and managing OpenShift is really easy and I'm really interested on a VM operator pov. I have a k8s and OpenStack background and I'm really interested in your opinion. If that's not your thing I'd like to see some coverage of Harvester. I really am interested in solutions that have strong Kubernetes integrations like CAPI providers and csi drivers.

Why nobody mentions where the OS is going to be installed, or where it is already installed? Some internal component? SSD? Where is it?

Anyone transitioned from normal alice to Q10? I find this keyboard hard to use because the macro keys messes up my typing. Its 2 days now and im still not used to typing on this keyboard. Anyone have suggestion? how long for you did you get used to this keyboard?

Great interview Rich ! That would be very interesting to have an interview with other big players, such as Promox, XCP-NG, Nutanix, etc. While they don't really need that much exposure, it would be interesting to hear about the way they envision the future of virtualization.

It would have been a better video if exactly what the product does compared to the industry standard, ESXi before going into the details after bragging.

Alright, the video is quite misleading. Windows Server 2022 Hyper-V Server Role supports up to 1024 logical processors, not 512 as you mentioned. Regarding memory support, it can handle up to 4 PB for hosts that support 5-level paging and 256 TB for hosts that support 4-level paging. The maximum limit for VMs on a single virtualization host is 1024 active VMs. The maximum count of clustered nodes is 64 physical systems, with a maximum count of 8000 VMs per cluster. More about VMs: - Virtual Machines can have up to 50 checkpoints (for the VMware team, checkpoints are known as snapshots). - In terms of memory, a single Gen 2 VM can support a maximum of 240 TB of RAM, while a Gen 1 VM can support up to 1 TB. - Each VM can have a maximum of 4 Virtual Fibre Channel adapters. - Up to 2 Serial COM ports. - A single Virtual floppy device. - The maximum virtual hard disk capacity is 64 TB for the VHDX format and 2040 GB for the VHD format. - Up to 4 Virtual IDE disks. - Up to 1024 virtual processors for a Gen 2 VM and 64 virtual processors for a Gen 1 VM. - Up to 4 Virtual SCSI controllers. - Up to 256 Virtual SCSI disks. - Up to 68 Virtual network adapters (64 Hyper-V specific network adapters and 4 legacy network adapters). Hyper-V offers multiple management options, and it's incorrect to say there is no alternative to vCenter. The Microsoft alternative to vCenter is called System Center Virtual Machine Manager (SCVMM), which even allows you to manage multiple vCenter Appliances, including Hyper-V hosts, from a single administration point. Additionally, Hyper-V can be managed in various ways, including Hyper-V Manager (Microsoft Management Console Snap-In), System Center Virtual Machine Manager, Windows Admin Center (an HTML5-based web client), Azure Arc, PowerShell Hyper-V cmdlets, Failover Clustering (Microsoft Management Console Snap-In), and WMIC.

Can you please also cover the HPE KVM player in the horizon?

Any one know how to downloaded the community version there website doesn’t accept regular email domain to register

Are there any that run on windows and do hardware passthrough? Not looking to make a server for a single use case.

Wait, so you need a whole other machine with a whole other OS? Pass. I'm just looking to pass a single card to a single VM, I'm not looking to build a fricking server.

Great interview!

I still mainly use XCP-ng Center and the command line. But i look forward to XO Lite. One day I'll deploy my k8s cluster, and then I'll run full XOCE

Wow. I had no idea i was an early adopter of XCP-ng. lol It came around when i needed it, just as I got tired of ESXi back then.

We switched to Thirdlane (from 3CX). It's a highly underrated company with excellent support, and we've saved a significant amount of money.

Ok so i am setting now my new truenas server just for 4k movies backup and streaming,., since i am having 2x 12 TB HDDs with 4k remuxes... Should i mirror then or raidz2?? Also what should be my ram?32gb? Thanks!! Should i mirror

Thanks for a great interview. It would be really great to be able to try out the HCI and VDI solution in a Home Lab environment, perhaps even run it as a nested solution for testing purpouses (Like a Community Edition).

I’ve seen the Scale Computing sales pitch a few times over the years, but getting hands-on with the software has been difficult. They seem really interesting but are incredibly b2b focused which has been off putting. They try to sell to C levels rather than infra managers. I’d love to see more about the product by getting hands-on. They need to work on making the software not look so much like vaporware. They talk a lot about how it’s HCI, how it was the first, etc. but they get cagey about demoing it to technical folks, in my experience.

great piece also for linux users ;)

It would really be great if you tried out Harvester HCI from SUSE. I am a huge of this open source project and this kind of sizing is perfect as a Harvester use case.

nice work! Now build an "absurd" home AI server 😀

Great vid! Thanks for the share, I honestly never had heard of them either. Gonna take a look!

I would love to get my hands on the homelab version.

I'd love to see a proxmox cluster with Ceph and a bunch of VDI VM's running off of it with gpu passthrough. Would make 16 or even 32 very high performance workstations if you can slice up the GPU's enough. Proxmox templates would help build all of those instances.

I wouldn't mind the homelab version, but I also don't want a fully restricted model. I have one customer where we provide co-managed IT services, and it's been a significant learning curve.

Me Second !! Love this !!

Wooot love the content. Thanks!!! First!!!

Can you say something about power consumption?

head shaft are down... need to buy new heads or try with old drives..

Noctua recomments the 5 dot pattern for LGA 1700 and AM4/AM5, but you have to add more paste in the center than you did. A 3-4mm pea in the center and 4x 1-2mm dots near the edges Works just fine.

That beast has afterburners!

This is good content: A topic I'm both interested and invested in. Punchy, succinct and impartial with a smattering of opinion with clear justification but not shoved down your throat. And less of an onus on brand and glitzy video editing than the last time I watched one of your vids all the way through. I think you guys will get closer to the subscriber count you probably deserve with this sort of focus. Just my opinion based on my content consumption preferences. Good job, look forward to the next relevant video with non-sensationalist thumbnail 🙂

Thank you so much for taking the time to put this video together.

xcp-ng with XOSTOR!!!

500Gb seagate with 41880 hrs Lenovo laptop 4621 starts /stops the one I am typing right now.

Now do Scale Computing

It’s curious that you and many of the other home lab developers question placing some of the items behind paywalls that you’re complaining about. Especially when you can compile from source and build whatever you want, the compile from source does not include support. At least it's not official support. Suppose you’re going to run this in business, or you’re going to run this on something that is mission-dependent or mission-essential. In that case, you will undoubtedly want support and wish all of these features were available and running and supported by the developer. This is why the walls are where they are. It is to slightly nudge the more minor, slightly cheaper businesses that they would if they could get away with paying absolutely nothing. Still, if you tell them that they have to pay a token amount, they may consider at least paying the token amount to continue paying for the entire system's development. As far as a home build version is concerned, it is accessible on the Internet. Be done with it, enjoy yourself, and learn. But if you want to put this into a business where it’s essential for the service to be running, reliable, and supported by the developer, then make sure that the company buys the correct licensing or at least some form of licensing.

Getting wrong rails from ebay sellers is super common. I have several boxes full of useless rails I've gotten. Only twice have I gotten a server that either didn't have rails or the wrong rails, and the box-o-rails delivered. I don't know what is with SuperMicro, but their rails kits seem to be hyper specific to single models.

Thank you for this series and this episode. I was highly dismayed to learn about the restrictions on ESXi. I had dabbled with it but never had the resources to get serious with it until recently. I also must thank you for acknowledging your dislike of Microsoft products. You did a fair job of comparing the Hyper-V. I was even happy when you acknowledged that "Windows Environments" may already deal with the complexities of Windows and may not see them as a disadvantage. PowerShell will set you free. 😇 I would point out two things. Windows Server 2019 Hyper-V is free. I would point out that Hyper-V 2022 is just the cost of Windows 11. The kernel of Windows 11 is the same one in the Server edition. It includes Hyper-V 2022. I would also note, there are several ways to install Windows without the Hardware tests, including one switch called "server". It does make the semi-annual updates more of a manual process. Lastly, if this is a bit too much, I would point out that both Server editions come with a 180-day "all features enabled" trial. Not free but as you pointed out, everyone deserves to be paid for their work. If you choose to do some more reviews, I would ask for QEMU/Virt-Manager and maybe Citrix Xen? Thank you again for your time. Keep up the excellent work.

Okay, before i insert the comment: I would like to see a massive Kubernetes cluster on those 4 Nodes! The amount of containers would be absurd. But you can stack them in Namespaces, the auto-heal capabilities lets you easy pull out the nodes live when the Kubernetes cluster pulls up the containers elsewhere. And Containers are the god king to effective use every last of resources on servers on a massive scale. And the core concepts of Kubernetes are fantastic made, because it’s declarative: Say via YAML what you want and let the automations take care of the rest. Would be nice to have such a big server, so much more power and ressources, hosted on prem. But the energy costs 😅 that lower my excitement, not gonna lie. Back to my initial comment: I‘m at 8:56 and what surprises me the most is the price for the cpus, i was sitting here like DOE?! The Chassis is a very good deal, the RAM, yeah ECC that always costs a ton of money but the upgrade capabilities means you won‘t get out of ram in the next 50 years. But what gives me a headache are the wd blues, i had issues with the HDD SATA ones of those, until i grabbed some more cash and when to the WD Red SATA HDD, and what i can say: My initial stupidity was thinking „well, I exchange them in my NAS when they going down“ but FFS they don‘t go down. On the current level of degeneration they will survive me and my dad 😅 i went lately one my server trio after the NVMe SSD begun to fail also to a WD RED NVMe SSD, currently on Amazon for 87 Bucks each and a PCIe to M.2 Card for 17 Bucks each. Will test it out on my first server, to put them in RAID 1 as the boot disk for my proxmox instance after migration the existing installation of the failing NVMe SSD to the RAID Array. When they degrade as slow as the SATA HDDs then if will have a lot of time with them 😊 and i will begin to switch out the main NVMe SSD on the other 2 servers to the same setup. And add an RAID 5 for data to each server on the long run. Currently my HA is degraded but still functional, that was the initial reason to buy 3 servers for HA Subscribed and Like already for a fellow server geek like me 😇 But one constructive tip: Please reduce the bass on the „building music“ that hurts a bit for headphone users

After your video series for the hypervisors, I'd love some to compare the full management stack of VMware alternatives (vCenter vs... x) and their potential administration overhead. Have a good time with this beast! 😉

Can you do Sangfor? Only if you can.
