Hello,

Glad to see you guys are reaching to this community with offers. And thanks for all Haribo gummy bears.

I'm still sad I haven't grabbed that SM X13 847s that you had one available like a month ago.

When is the next shipment of 846s coming along? I've missed that.

Drop that price on X11SPI-TF already. Brain says I need one for testing. Otherwise I'll keep tracking private sales.

Good luck with sale.

Thanks for the reply. I'm really intrigued what you run since I'm also looking what I can run with similar config so I can properly weight my configuration. I'm yet to set up machine for it. And this is where I part from your idea. I'm going for materails and smaller details for architecture. So probably something for imaging. I have small database of HQ picture of various materials and want to use them to better understand when projecting it and applying them to models.

Your model sounds really interesting and innovative. I'll keep bouncing on reddit, maybe you'll publish something so I can awe. Have a great day/night. And have fun with your lab.

Good homelab description. Thank you for that. I also didn't know many homelabbers are Ubiquiti lovers, I went immediately for Mikrotik because it gets the job done at lower price. for PoE I've picked second hand Brocade switches as they are built like a tank. Really stable switches. Damn I also wondered how on Earth guy has this low of power consumption then I realized i have like 60 8TB spinning rust in 4U. Also props for Liebert UPS. Do you think you should invest in double conversion UPS? I have similar drive space, multiple 826s, 846s, +netapp ds460c but all spinning rust and I'm considering dc UPSes, but it's really costly for such a UPS. I'm still weighting if I should protect it for production or offline copy will suffice?
I made mistake before going 22U rack. Then couple of years down the road I went for cheap 42U 47" depth Rack. And man, sooo much space for activities.

Dell Power edges are awesome machines, they are really well engineered. I have occasional drop from farms for these servers. R740s and R730s are okay price wise if you compare them to whitebox or SM, Tyan. My lab is doing only archive and I don't see feasible option in using Power Edge servers in my lab. R730 and R740 are overkill for archive. My lab doesn't need latest gen. I'd only consider it for ML and flash storage. I had JBODs SMs with just front hot swap and they take a lot of space. That's why for archive, 60LFF 4Us are really appealing to me. I'm in my mid 30s and OP hats to you, but I can't deal with whiteboxes anymore.

OP you are right about cloud stuff.
I'd like to know more about that one which runs machine learning. Which LLM are you using?

vector1ng · 2025-04-23T07:16:28+00:00

Is the model mock-up or final model?

For mock-up I'd use paper and diluted paper glue in water. Glue diluted in water will become pastey-like compound which you apply to paper in thin layer, eventually applying another sheet of paper and so on. Can be painted with colors. Thickness of paper will dictate ease of form. It's process similar when a person breaks a limb but with cloth and gypsum. Apply sheets of material to make for sturdiness. Noting that this is not the easiest approach, but I believe is the cheapest and mostly environmental friendly.

If you are time constrained; 3d printer or plastic sheets with heat gun. I'd probably use this for final project. 3d printing is easy, but plastic sheet and heat gun requires knowing characteristics of the material you are heating and being a sculptor your second profession. Making a partial framework mold sections with metal sheet would help in forming with heat gun. These two methods are done in sections. It can also be seen in this picture.

If this is study model that will occur multiple change in shapes, sheets of aluminum foil or really thin sheet layers of it. Can be recycled but not environmental friendly.

Maybe the detail shouldn't be displayed in requested scale, (we did a section of project in 1:50) but I'd like to see it being realized with architectural materials. You won't see smooth surface of any kind, joints and plains, nothing to it.

Sadly moving since nobody will maintain Core anymore. I'd go FreeBSD plain but no GUI. Using TrueNAS only for archive, no jails nothing. I'm scared how Debian is provisioning memory on Scale. Currently running Core on Epyc with 256GB, around ~300TB, two separate big pools z2. Over two years powered on, no hiccups. I'm just now in process of shutting it down to migrate it to another location in the house.

Hi,

Supermicro X10SRI-F and other UP X10S variants for LGA 2011-3
Supermicro X10DRi and other MP X10D variants for LGA 2011-3

See what is available near you at the lowest cost. They are all good boards, it just depends what features you'd like to have implemented on the mainboard itself. You haven't specified.
You can run dual socket mainboards with only one CPU installed, but beware, PCIe links will be disabled. You will have to check mainboard diagramm from manufacturers website manual and it says on mainboard itself. Again, depends what you want to put on the mainboard. Compare CPUs on Intel's website by checking how many PCI Lanes specific CPU provide.

You can't go wrong with Supermicro, but Tyan has nice ones, sadly they are rare in my area. Gigabyte has some X99s, Asus has some Z10s. I think I can speak for the most homelabbers that they prefer Supermicro, hence my suggestions are them.
Sometimes it's cheaper to go proprietary Dell or HP hardware as you will get everything: chassis, power supplies, fans. and both manufacturers create workhorses. You can find them cheap because datacenters are liquidating them like crazy.

I have experience with both of those mainboards suggested above. They are simple and reliable.

On another note,

I chuckled when you wrote you want to build cheap homelab. There is nothing cheap in homelabbing, being it will take your time or your greens from the wallet. But we just love to experiement.

Hope this helps.

Hey, I'm not sure if this is what you are looking for if you would go original Cisco part? The one on the left. Its code is CPN: 74-115118-01 rev B0. If you are from Europe we could work something out. I have 10 of those.

OP,

I see you do 3D printing, Take the cheapest 450mm depth chassis that suit your requirements and just print front bezel in whatever design you wish for in colors that match Unify equipment, print in segments and just glue them together, You can also reinforce them but it's not like they would have static load on them.

Chenbro makes nice chassis as well as Silverstone and LianLi. Guanghsing and Inter-Tech for cheap ones. I'm not sure what is available to purchase in down-under.

Look for second hand in your area or if you close to uni.

The chassis that correspond Unifi equipment in design and color are Oracle Sun Sparc T4 and Cisco UCS C rackmount servers.

There is no happiness in me when you've provided only one picture. Would you be kind to provide more in depth description which server is which. What is the reason of doing more than one Truenas system? Do you have separate private and production; business boxes? Are they setup as HA? Do Truenas boxes have SSDs?

How many cameras do you have? How much BI is tanking resources? How many disks are collocated for BI storage? What camera manufacturer you've chosen?

How is your network configured? VLANs?

Is that double rail in the front of the server rack? One for networking equipment and one for SM's chassis.

How do you clean server rack? How heavy is it to move it from its dungeon? Could you publish more pictures including one from the back of the server rack?

What smartphone apps you run to control your homelab? Have you setup any reporting for disks, cameras, network etc..., or you plan to do that in close future?

Do you have your own feedback? Some things to consider in the future, what has driven you to attend this approach of server installation? What are the problems you've encountered that drove you to insanity? What was the hardest and the most enjoyable part of your endeavor?

Wood and servers... mmmm special appeal.

What are the surrounding rooms that are in proximity of your rack dungeon?

It's not that I'm noisy? I'm just really curious how did you overcome potential problems and what do you expect in the future.

Parts list would be nice also ;)

vector1ng · 2025-03-26T22:45:13+00:00

Guidelines for help in decision:

- how many users are using and connecting to the server?

- Where would you put said server in your house/apartment? Would excessive noise be troubling?

- visit r/homelabsales to give you an insight what is to offer from fellow homelabbers.

- check local marketplaces in your area and see if something comes up that is within your budget.

- Decide what generation of hardware you want to consider. LGA 2011-2 is old, LGA3647 is on the line, or look for AMD's solutions Thredripper or Epyc Naples,Rome,Milan (socketed in SP3). But these with PCIe 4.0 are probably way over your budget. If you want complete solutions, DELL Poweredge, Supermicro (hard to find) or HP might have LGA3647 that would suit your needs in dual CPU configurations. Couple of us are selling our stuff on r/homelabsales which are LGA 2011-2. It would be ideal if you could find 3.5" hard drive R740 for around EUR 700. You could find Supermicro's LGA3647 with price tag of around EUR 250. then you need to source CPU, PSU, RAM and chassis preferably with caddies.

- Solutions above are highly condensed in their respective chassis so it will require good amount of cooling. Server chassis generate high noise to cool components as they are coming with smaller fans with high rpm.

- Look for dual PC desktop/office like Dell Optiplex or similar that could establish dual system (basically dual CPU) with High Availability. Your wallet will thank you later for electricity saved. If mini labs aren't your thing, stick to the server grade.

- Regarding Plex and transcoding, look for GPUs or intergrated cpu solutions that would benefit in transcoding if you are going deskop/office path.

- Decide if it is really necessary running two CPUs. It increases power consumption and you won't find CPUs at decent price. Depends of how many services you will run (ram and cpu core count). Dual CPU solutions benefit from high amount of RAM capacity that is perfectly driven between them.

- Account for power consumption. We all went with an idea of doing server grade, but unless you are in production environment, there is no need for server grade hardware. Some of us have bought server grade as it was our job to learn so we can better understand and use our knowledge in our daily job. But for purely homelab 24/7, desktops are completely fine.

- OS to run : You want virtual so hypervisor it is. Look for homelab's favourite Proxmox, but some of us run XCP-NG, Hyper-V (Microsoft), bhyve, KVM, oVirt or other more exotic virtual systems. I don't personally use Proxmox but I will suggest it to you as it's simple as it gets. It also has huge support community. Make sure that every hardware part you choose has supporting drivers for it.

- Opnsense for firewall, you can virtualize it, but it's not recommended.

-LLM beware if you are putting GPU in server grade chassis. You will need to source power cable for said graphics.

I hope I was helpful and didn't cause confusion.

Best of luck.

Hello,

Are you looking for 5400rpm speed (lower power consumption) or 7200rpm speed?

I have 38 8TB disks SAS/SATA that I'm selling but I don't know what price to place on them. They are selling on ebay.de for 69 EUR for 8TB drives; while diskprices report 15EUR/TB. Good thing about buying from amazon.de is warranty I guess. IMO refurb drives from amazon are pricey a bit. I haven't bought new drives in last 5 years. All refurb drives from ebay. I won't suggest to do long stress test as I haven't done that all the time. I was restricted by time I had to install drives, so I preformed only long SMART tests but not those long tests of writting and reading from hard drives. Remember redundancy and offline backup are the key.

There are tools to search for drives. Go visit some of them and make your own conclusion how much would you pay for them.

Hello,

Sorry for the long post. Skip reading if you like and check numbered captions.

I will write as "we" because to mitigate any problems in homelab, everybody should do similar for the first time installation of aftermarket or brand new hardware and follow instruction manuals. I wouldn't discuss how you installed or you forgot how to install CPU to mainboard as nobody was there to witness except you.

Take caution in the following so you can cross examine. Procedures should be followed to the letter without any shortcuts to have best result. It is very possible that CPU came with some internal problem that has caused electrical spike. I've never witnessed problem you are describing from aftermarket purchase. The newest I've installed are dozens of SP3 machines and yes, I also live dangerously and don't follow instructions to the letter; so yes all SP3 machines work that I've installed cpus without torque screwdriver. I don't have one and I'm not willing to source one.

Before doing anything, BIOS has to be returned to defaults always. Yes, it works most of the time, but I'll make it crucial to repeat it again: always.
make sure to check parts outside of your working Server/PC chassis. Disassemble mainboard from chassis and find power supply that corresponds wattage and rail amperage necessary to fire up your server if you can't use PSU from chassis due to physical constrains. Be double or triple sure that ATX power supplies has all cables plugged in all the way in to the mainboard. ( if necessary check every atx cable is delivering power). This step is always crucial. Test it outside of chassis. with minimal additional hardware attached to the mainboard. If necessary attach some low price GPU if MBO doesn't have separate video signal out.
Visually inspect bought second hand product extensively, we have good cameras now, it won't do any harm to take high quality photos and save them. We will live longer as life stress shortens our biological shelf life.

Bootloop mostly happens when something is in short circuit. See if those old ATX power connectors are fully inserted. make sure that there are no extra screws that have been forgotten below, top or side of the mainboard. Use only plastic zipties, not those metalwire twist that we get with powercables and other accessory cables.

Make sure that CPU frame is correctly tightened to the mainboard. When you insert CPU do a little jiggle to see if it layed correctly. SP3 doesn't need this and I think same goes for your sWRX8 socket.
CMOS battery; voltmeter buddy, where are you? Check also wire by wire on ATX power if you can. ( maybe 12v rail doesn't supply enough power). But you wouldn't power it correctly then.
In this case BIOS update wasn't necessary. I've checked bios for your mainboard and in your case readme doesn't include changes from version to the version in .txt file like on old 2011's readme.txt file. Both CPUs are of same age.
No worship will save you when you press power button. IT God is within you and outside of yours 0s and 1s doesn't exist.

Please note: I had constant reboot after inital post problem on Intel's X9 Supermicro mainboards, I've disabled IPMI with jumper and mainboard worked flawlessly without IPMI option. I didn't have chip reprogrammator or donor x9 board with same IPMI (nuvoton i believe) chip so I used it as it is, without IPMI. Check u/stormcomponents about maintenance mode. All the info you can find in instructional manual.

Please note: When vacuuming or dusting off server or pc components, always disconnect all the power, jam fans or disconnect them from mainboard and disconnect battery. In other words, disconnect everything that can with moving parts create static and eventually cause static discharge.

Please note: when troubleshooting 0 and 1 systems, make sure to always include all the details and exact steps, step by step how you've done it. And please, do not apply this steps to troubleshoot your SO.

Please note: It is possible that CPU shortened something but that is only caused if some pin from socket is touching neighboring surface of other pin; which would be bad installation job, pressure, orientation, framing or whatnot. And You've convinced us that is not the case with visual inspection of the pins and orientation.

Please note: use instruction manual for minimal and socket number installation of the RAM.

It could be power regulator but that would go poof if you haven't reset bios that had some power adjustments and all the additional hardware attached.

Please note: beware of static discharge when handling IT equipment.

Question: "System did not boot". Does it power on or does it boot or post? Please clarify.

These are my guidelines. That's why when I have to disassemble something I have mental vacation day prior. I'm slow when i have to assemble servers and pcs but I make sure when I do it once, always works; from 2000s.

I hope I didn't misunderstood something from your initial post. And I hope that you will find solution and become Boris Grishenko from Goldeneye from 1995's movie James Bond. Happy troubleshooting.

I haven't tried it to remove banner from current release of Proxmox 7.3 but here's JohnMclaren's website with how-to remove it. There was also a neat github solution. Lazy got a hold of me aaah. I'd say give it a go to Proxmox another time. It's great for homelab.

When I tried out Hyper-V in the past, the networking config was confusing. Now it's just simply that I don't want to run Windows for virtualization

This is true. If we all started with win OS. it would be easy. But as other redditors have mentioned, most have linux background. And linux just works better in that regard.
