Glad you went for it despite our poor documentation cb22! That sounds like a great setup. I think the only defensible way to describe our "Requirements" page is that we wanted to make the safest suggestion for the widest range of users. Obviously it's wildly inaccurate for a wide range use cases, and we should fix that.

Nomad servers could start with 300mhz, 100mb of memory, and eMMC storage and run a RaspberryPI cluster just fine. Our most important resource guidance is all the way over in our Monitoring docs!

> Nomad servers' memory, CPU, disk, and network usage all scales linearly with cluster size and scheduling throughput.

Any cluster can start with 300mhz and 100mb as long as they monitor usage and scale appropriately.

We're going to try to update our Requirements docs to add this nuance and guidance on how to calculate requirements based on projected load. We recently spent some time improving our heartbeat docs, and I think the approach we took there will serve us well for system requirements: https://developer.hashicorp.com/nomad/docs/configuration/ser...

See this is the sort of information that they should have posted on the requirements page. Not some arbitrary sized high water mark needing gigs of disk and memory. I'll have to give using Nomad (and Consul) another go next time, and test it on physical hardware to see.

Thanks for the info! and for doing what Hashicorp seemed too busy to do themselves.
