Best advice for scaling to managing a small mining farm

Hey all! I’m looking to scale from a small home mining set up to something much bigger. A new space with a 3-phase set up with the plan to grow to 20-40 machines. A mix of mostly L3’s, S9’s and some S19s. Then over time scale or upgrade. Hopefully it works out!

So what’s the best advice from some of you more experienced with this sort of scale? What advice do you wish someone could have told you?

What’s the best way to manage that many machines (hive, minerstat etc?)

Any tips for cabling / setting up?

Simple things that make life easier (labelling machines, how to organise best for troubleshooting or monitoring so you know which machine is where etc).

Tips for airflow management?

I have tried to look for articles on this but if anyone has useful resources covering this that’s also great.

Thank you !
