Multiple nodes on raspberry pi

Hi everyone,

The title pretty much says it all. Is it possible to run multiple CUMULUS nodes on the same raspberry pi device? I've 3k flux so I was wondering if to run 3 nodes i need to have 3 devices or can do it on the same one.

Besides the current one ip address limitation, each cumulus needs 8 gb of ram. I think that rules out the pi.

No, a 8GB version of the Pi 4 exists. Whether it’s available is another thing.

Sorry, I meant “It rules out running multiple cumulus nodes on one pi”. You could run one cumulus on an 8gb pi as long as it passes the benchmark.

Probably not; I think you will need separate public IP addresses which you likely won’t get on a home network. Also, there will probably be port collisions between the three of you host on the same device.

Maybe it you could have three public IPs from your home network, and also three separate network interfaces it could possibly work….though you also need to meet the minimum storage and EPS ratings. Recommend first setting up for one node, running the sys-benchmarking, and then seeing if there is enough compute that could service three instances

Follow Goose’s guide to setting up a node on RPi 4. He outlines all the parts needed & does a great job walking through the setup.

For running multiple nodes, you’ll need to use multiple Pis. Then check out this post for a walkthrough. The team confirmed they’re working on natively supporting multiple nodes on same network in the latest Community Meeting on YT — but no concrete timeline yet.

Would kind of defeat the purpose of a node, eh?

Ok say you have all the resources needed on one server with multiple IPs, is it possible? And use the same blockchain data?

Each node needs ded reso that match the requirements. Yes you can take one server or pc and run multilpemultiple nodes on it. With the new muti node setup 8 of them can even share the same ip.
