How many controller is recommended for a 12-nodes cluster

Support
1

Hi Nazar,

Please help to confirm if my cluster configuration is correct or not.
12 nodes:
server 1 runs node, controller, cache(200GB), nats
server 2 runs farmer
the rest 10 servers runs plotters.
Is above configuration OK?
Should I run controller also along with plotters on the 10 server?

There is no such recommendation. It depends on many things like hardware, network links, etc.
Try and let everyone else know how it went for you.

You generally don’t need to run controllers on every machine, but it might be helpful to run more than one for redundancy.
