Zimaboards do not need RAM. They include it (do not confuse it with the Zimablade).

I just use the default hardware with the Zimaboards. Zimaboard 832s for the masters and nodes, and I recently added a couple of Zimaboard 2s for larger nodes as those have 16gb.

I like the boards, they perform well and the intel cpus in them have internal GPUs so for light transcoding or GPU loads they can be leveraged without need for GPU cards. After trying several other x86 based options, Zimaboards are my preferred option.

I used Zimaboards. They are affordable and all you need if you couple the cluster with a TrueNAS Scale box and setup Democratic CSI.

Kube makes it easy to have a lot, as a lot of things you need to deploy on every node just deploy on every node. As odd as it sounds, the number of containers provides redundancy that makes the hobby easy. If a Zimaboard dies or messes up, I just nuke it, and I don’t care whats on it.

Uh… Probably somewhere around 150?

Was super interested right up until the AI recommendations bit.
