Let's share our farming setup

Hello Threefold farmers :slight_smile:

I created this thread so farmers can share their farm setup.

So you if you have your farm up and running, feel free to share your setup:

  • router
  • switch
  • network configuration
  • pictures of your farms
  • screenshots of management UI from the switch and routers

The idea is to try to cover as much brand, vendor and hardware as possible so future farmers can have a look here and have a good idea how they should configure their farm.

I will keep track of the post here and try to consolidate them into the official documentation of 0-OS.

Few rules to try to keep this organized:

  • Make 1 post per farm. If you have some new info to add, just edit you post.
  • Let’s try to keep the chit-chat to a minimum inside this thread itself so it stay as focus on topic as possible. If you have question on a specific, open a new thread and reference the post you have question about.

Sorry for this huge post sometimes i exaggerate…

ZeroOs V2 Buils is coming soon…

Build with ZeroOs V1 – working well

About the Project

Im a lonely enthusiast who is settled in Lower Austia near Vienna. My Servers are - by now -located in the cellar. I worked hard to have 2 additional Currentcircles as well as a nice Networkconnectivty in this cellar.


Primary 1: Produce capacity to build a better internet in a better world. For the nature for the humanity and for me and my carma as well :smiley:

Primary 2: A lot of fun working in this proejct

Secondary 1: Generate money to live and to finance energycosts as well as to upgrade capacity or to build a service around it

Secondayry 2: Want to offer a service for small business and people who want to set something up on the TF-Grid, without thinking about technical stuff.

Secondary 2.1: want to run my own developed Software on the TF-Grid.



Current i have a connection with static IPv4 Address and also an IPv6 60s Network 150/20 mbs

Planned is a second connection with IPv6 and Upload over 50 mbs

If everything is running great, i will rent a flat in Vienna for better connectivity and room-temperature .

Router / Firewall

I use a OpnSense (opensource BSD-based) all in one router where i can configure everything. I can highly recoment OpnSense! There is a huge community around OpnSense and PfSense.

PfSense and OpenSense uses the same ground architecture.

Configuration of opnSense


WAN Interface IPv6 Settings

DMZ Interface IPv6 Settings

FireWall DMZ Interface (all out allowed, all to LAN blocked)



Current i have 4 Servers reserved for Zero Os.


Each Core has >8GB of RAM.

My plan is to run SSD only servers (for me as small farmer its cheaper than running HDDs)

I have also an HPE-Server and in my opinion DELL and IBM makes better servers in quality and technical-architecture (except Management Software) … but i can only talk about generations in the time of sockets 1567 and 1366… maybe new HPE Servers are better.

2x DELL PowerEdge R910

Each has….

  • CPU: 4x Intel Xeon X7560 L – all together 80 cores
  • RAM: 44x16GB (704GB)
  • SSD: 0TB (current)
  • HDD: 0TB (current)

Pros/Cons of this Server:

++ Well done modularity especially the RAM-Modules, where the RAM-Module with error is highlighted with batterypowered LEDs.

++ Very good Management WebInterface

++ Good quality (no plastic parts like HPE)

++ Huge number of PCI slots

++ Silent (for a server)

++ Drivers and documentations are well preserved

– To switch CPU you have to put all RAMs and FANS out

– The RAID-Module „PERC H700“ is hard to manage and Disks doesnt get recognized by ZeroOs V1.

– It needs 4 Powersupplies with 1100W per each. If you use less it gets errors and downgrade the system.

– The buildin Broadcom 5709C Controller is not supported by ZeroOs V1, an additional NIC was necessary.

2x IBM System X3850 X5

Each has….

  • 4x Intel Xeon E7-8867L – all together 80 cores (Most efficient CPU für Socket 1567)
  • RAM: 44x16GB (704GB)
  • SSD: 1TB (current)
  • HDD: 12TB (current)

Pros/Cons of this Server:

++ Also well done modularity

++ Good quality (no plastic parts like HPE)

++ You can directly change CPUs without removinmg any other part like FANs…

++ Easy do handle HDD-Backplanes and to manage disks

++ 2 big and in quality good Powersupplies with 1200W per each.

– Poor Management WebInterface whitch runs only in IE (but good enought to work with)

– Commands per SSH doesnt work like it should

– Extremely loud by 30° of CPU temperature…

– Drivers and documentations are poor preserved

– The buildin Broadcom 5709C Controller is not supported by ZeroOs V1, an additional NIC was necessary.


Current Zero-Os V1. All Up and running since months


Debian PXE-Server to host Zero-Os Images


All 4 Servers with ~30kg per Unit are lying on tables in the cellar.

A Rack is planned.



  • Farm name: “feorm”
  • Nodes: 1
  • First node online: July 9th, 2020
  • Node hardware: HPE EC200a with aftermarket memory/drives
  • Farm resources: 8 CRU, 63 MRU, 7452 HRU, 1907 SRU
  • Network: 25 mb/s cable internet link, standard consumer modem/router combo, default settings


Here’s my little home farm, with the first node hanging out by my modem/router:

The server is an HPE Proliant EC200a. I chose it for its small form factor, low power consumption, and excellent value. It boots via EFI from a USB stick (provided USB image did not work), and runs Zero OS v2 without issue.

My guess is that this model (and its hard to find add on storage unit) wasn’t a very successful product, given that the current HPE Gen10 lineup favors the microserver design fitting 4 LFF drives as the smallest option. Mine came from a vendor who was liquidating unsold stock. So these are brand new, though slightly outdated (within four years old), machines that were stripped of the original memory and drives to be sold separately. In my opinion, they are great candidates for running DIY nodes at home, so I bought two :stuck_out_tongue: Here’s the other one (backup for now, maybe outfitted later), showing my little terminal station for setting up boot configuration:

They came even smaller than I expected, as you can see next to the monitor. Specs are:

  • Intel Xeon D-1518 SOC with 4 physical cores @ 2.2Ghz
  • Two DIMM slots, up to 64gb memory
  • Two LFF drive bays
  • One M.2 SSD slot
  • Two NICs and one dedicated NIC for ILO
  • 120w external power supply

Here’s what an empty one looks like on the inside, and the M.2 spot on the bottom:

The node I have online is fitted with 2x32gb memory sticks, two 4tb HDDs, and a 2tb M.2 drive:

Total hardware cost for this node (all new, enterprise grade components): USD $686
Monthly energy cost: USD $8
Expected ROI: we’ll see, but I’m guessing pretty darn good :sunglasses:

Downsides to the EC200a as a node are that it cannot be certified and the fan is a little loud to be running in the living room all the time. I’ll be moving my router and node into a closet to help with noise (wish I had a basement, where it would also be cooler). My router is a standard consumer cable modem with a wifi router built in (Arris SURFBoard SBG10), connected to a 25mb/s Comcast cable internet connection here in Eugene, Oregon. Just default settings on the router, which thankfully includes IPv6:

And apparently some DoS protection too:


Future plans in consideration include adding more nodes, upgrading my internet package (more bandwidth and unlimited data will probably be necessary, especially if any more storage capacity is added and actually used), and utilizing the dual NICs on these boxes to expose them directly to the internet via the router’s DMZ (maybe no benefit for me, but sounds like fun).

I am really excited to be helping to grow the ThreeFold Grid as a farmer. It’s been a dream of mine for a while now to have a little box sitting in the corner generating cryptocurrency, but mining rigs have never appealed to me. Getting my node running was surprisingly easy, and I love that it’s part of a movement for evolving both the internet and humanity.
