What is the minimal system that would be suitable for this task? What kind of system and OS would you recommend for this?

Requirements for a Full Node


OS

I have found macOS to be the easiest to get up and running in the smallest number of steps. Your mileage may vary though.

Linux/macOS/Windows and anything else that can execute the iri jar.

GPU

Not required

CPU

At least 2 or more cores with 64-bit architecture

RAM

At least 4 GB or more

HDD

At least 50 GB of free space

Internet Connection

2 Mbps or better should suffice

Uptime

24/7 (or close to it)

Static IP Address

Required, visit here to setup

Notes

  • These requirements will change as more and more people adopt IOTA.

  • If you've ever configured a Bittorrent tracker it has similar system requirements to one of those.

  • What about Raspberry PI? The best model available right now would likely under perform. The CPU and RAM is a little too weak for the java implementation. There are other implementations in work requiring less ressources, through

    CPU needs to be 64-bit (at least on Windows) and Java Runtime Environment needs to be 64-bit too. – mihi Nov 28 '17 at 21:30
  • @mihi is that for the headless full node only or does the GUI also require 64-bit? I thought that Windows and Linux GUI builds supported 32-bit but I could be wrong. – vinnymac Nov 28 '17 at 22:11
  • The full node (iri) uses a database implementation (rocksdb) that cannot run on 32-bit JREs due to missing shared libraries for that platform. The light wallet should not be affected by this, although I have read that some people have trouble with GPU-accelerated PoW on 32-bit Windows 7. – mihi Nov 28 '17 at 22:14
  • What is the RAM used for? Could the node software not be adjusted to use less RAM? – w00t Dec 13 '17 at 13:35
  • I think the number of the Cores does not matter much. could 1. Mine is working great as 1 core, 4GB ram. – tawago Dec 29 '17 at 0:05

My personal recommendation:

Operation System: Linux (generally better for server)

RAM: At least 4GB. Better 8GB.

CPU: Quad-Core x86, ARM is not supported at the moment (I hope it will be in the future)

HDD: 150GB - 200GB, not necessary (just to have big buffer for the transaction database)

Internet Connection: 100Mbit/s or more

Why all these recommendations? If you want to have a secure full-node, you need some more neighbors. These neighbors put pressure on your node. If you want to share your full-node with friends, family, you get also more traffic/pressure because of the light-nodes. But: Just try it with the minimal settings and find your perfect setup :)

So the topic with your Raspberry:

There is a list of supported ARM devices.

Some Raspberry boards are supported. I haven't tested them yet. I have other ARM-boards and I cannot compile IRI on them. Probably the list is outdated (2016). The issue is the RocksDB database not IRI itself.

There are two discussions about this topic on the IRI github: the first one and the second one

At the moment 28.12.2017: A node should have at least 8 GB RAM. It's better to have more, because the machine, operating system and other services need some memory for themselves. The Java Memory settings should therefore be set one or two GB below the RAM-Size for 8GB e.g. to -Xmx7G

The node shoud have 4 cores.

The node should have a SSD with around 40GB space. The mainnet DB has around 9GB today, but is growing.
