All the Rasbperry Pi Nodes are equipped with Waveshare PoE HATs. The PoE HATs fans are enabled manually since the auto RPM control by software depending on the Raspberry Pi CPU temperature is not working correctly on Raspian 64Bit OS. Each cluster Node runs a single BOINC pod which has 3 CPU cores attached. The BOINC-client itself is allowed to use 100% of the CPUs and 90% of CPU time (to prevent throttling). So each node is about 85% used by BOINC-client. There is still some capacity left for Kubernetes or OS tasks.
Each Raspberry Pi Node currently draws about ~6 Watt from the switch in the current setup. I will try other configurations in future and compare them here.
[…] Btw Power consumption of each Raspberry Pi is now slightly increased with ~7W each. Information about default power consumption can be found here. […]
