I created crypto mining farm from zero as part of mini Data-center project.
Building the miners with specialized motherboards, server power supplies.
Running with ubuntu linux and yp to 12 GPUs per miner, all provisioned and configured with Foreman, puppet and ansible.
Additionally it was developed custom stratum proxy for all miners with custom control web ui and terminal ui with watchdog capabilities, auto restart, auto algorithm and pool change.
Monitoring with node-exporter and custom prometheus exporters for rigs and gpu performance, power draw, room and gpu temperatures.
