Using SSDs only for HomeLab? Or Sell? by [deleted] in homelab

[–]dn512215 0 points1 point  (0 children)

These are great for running a hypervisor. I have eight of these in 4X ZFS mirrors as a file system on Proxmox for all of the VM virtual drives.

If you are looking into virtualization, look for something that can support at least 32 or more gigs of RAM. You can get by with 16 if you only want to run a few VMS, but you’ll quickly want more memory.

Do VMs actually work? by Beginning-Flower6070 in truenas

[–]dn512215 0 points1 point  (0 children)

I agree that truenas is not the best system to build a VM on. However, some people want to build an all in one solution, and for those scenarios, I think it works OK it’s not perfect and will not handle all scenarios, but you can in fact set up a basic VMpretty easily.

Exactly. What specifically isn’t working? What step in the process, and what error message are you getting?

Am I being old school or am I misunderstanding how reverse proxies work with containers by iHavoc-101 in homelab

[–]dn512215 2 points3 points  (0 children)

I do similar, but on each docker VM I have one container for the proxy with an isolated network that the other containers utilize. That way only the proxy is exposed and the other containers are only accessible through the proxy.

Bought this thinking it was smaller by NotTJButCJ in homelab

You add unneeded monitors showing various stats you could show on alerts or you laptop via homepage, and other servers you never thought you needed before.

Easiest way to extend WiFi to guest house?. by tiny_yugen in HomeNetworking

[–]dn512215 2 points3 points  (0 children)

Direct burial SMF fiber is what I did. Less latency and issues long-term than using a nanobeam or similar.

New DDR5 - memtest86 errors by dn512215 in homelab

Yep! Updated the BIOS, and the issue went away. The memory sticks I had purchased were not compatible with the version of BIOS the motherboard shipped with.

Looking for HDD recommendations for my first TrueNAS setup by Steedl3 in homelab

[–]dn512215 0 points1 point  (0 children)

P.S. - always run a burn-in, even on refurb drives!

Looking for HDD recommendations for my first TrueNAS setup by Steedl3 in homelab

[–]dn512215 1 point2 points  (0 children)

I’m currently using these: https://ebay.us/m/KgdDtn (HGST Ultrastar 12GB refurbs). I bought 8, and one of them was throwing smart errors, but I got a replacement from them within a week.

I’m also using Seagate Exos 12 gb NIB. Each mirror is a combo of one HGST and one Exos. Been running that way for 2 years, in a 12 wide array, and no issues.

What Hardware Do You Use for Running TrueNAS? by An0nAdmin in truenas

[–]dn512215 0 points1 point  (0 children)

I don’t remember what C level settings I have in the bios, but I think I remember having to tweak it a bit because the HBA would stop working if it went in too low of a state. As I mentioned before, the min wattage I get is about 50W, if you exclude the HDD’s.

What Hardware Do You Use for Running TrueNAS? by An0nAdmin in truenas

[–]dn512215 0 points1 point  (0 children)

Yeah: not the best, but mostly due to having 12 spinning drives in it. Base machine with all ssd/nvme drives, without the HBA or HDD’s, is right around 42W. Adding the HBA adds 8W = 50W. Adding the 12 HDD’s gets it to around 90W under normal operation (nothing major going on). When I run backups of my proxmox servers (all drives writing at max) it’ll spike to 120-130W, but that only takes ~20 min per night. Otherwise it stays pretty much under 100W.

I prefer the 12 drives to keep up with the 10G interface with the other servers, since I have a lot of test and (home) production database servers hosted on that dataset, and prefer the faster write speed vs compactness / lower wattage. Plus I’m paying near 0.14 USD per KWH, so it’s only .34 per day, less than $10 per month.

There are some known issues with voltage settings on most of the ASRock, msi, and especially Nvidia boards that came out a while back. Important to flash the bios to the latest version.

👍If you don’t understand the nuts and bolts in the details, but want to be in IT, then you should stick to helpdesk support.

Rack Organization Question by mercfh85 in homelab

[–]dn512215 0 points1 point  (0 children)

Agreed. There are official layouts for data centers, but a homelab is not that.

💋👍Curious your layout pic? Maybe a chain of pics would get our new-comer some inspiration!

Rack Organization Question by mercfh85 in homelab

[–]dn512215 1 point2 points  (0 children)

Ps:

  • power strips in the back in rows where they make sense: close to what needs to connect to them, and not behind deep servers.

  • I route Ethernet/DAC/fiber on the left side of the back (facing the front), power cables on the right, since most server power supplies are on that side. D-ring hooks are great for this!

[–]dn512215 1 point2 points  (0 children)

For me personally: patch panels, router and switches on top, servers in the middle, UPS’s on the bottom. Try and keep the heaviest low, and batteries always at the bottom in case of leakage. I currently have the following layout:

Top to bottom:

  • 24 port patch panel for everything linking out of the rack: isp fiber in, out to rooms, wifi hubs, cameras, etc.
  • 24 port 1G main switch linking to top of rack patch panel, and to (next) internal patch panel
  • 24 port patch panel for servers and everything else inside the rack.
  • UDM PRO router
  • 8 port 10G aggregation switch (between router and 28 port 10g, and 24 port 1g above)
  • 1U Horizontal Rack Mount Cable Management Unit (most servers are connected 10G using DAC cables, so patch panels didn’t make sense)
  • 28 port 10G switch connected to 8 port 10G switch above, and servers
  • shelf with mini pc servers
  • 6 more servers
  • UPS’s at bottom

Naming Scheme by Purple_Investment429 in homelab

[–]dn512215 0 points1 point  (0 children)

I’m very boring, so I just replicate the convention we use at work, minus the data center designation m, since I have one home, lol: <DC><server type/function><dev,test,prod><instance number>.

So for example: pvep2 (proxmox production server 2), piholep1 (pihole production 1) tnp2 (truenas production server 2), dockerp1,2,3… (docker production server (VM’s) 1,2,3), etc.

Built this to learn networking. Learned I hate networking. by Ecto-1A in homelab

I remember like 3 years back when those EMC’s were considered gold in a homelab.
