Dell PowerEdge R730XD FanSpeed Controls via IPMI
R730XD can auto control the fan speed by default, but when plug in a PCIe device which is not in the iDRAC database, the fan speed will boost almost max.
Formerly, with ESXi installed on the server, the sensor readings can not be easily got neither in vm nor in host just use sensors.
To automatically adjust the speed, I use ipmitools to get sensor readings.
After Broadcom acquired VMware, I uninstalled all VMware products. I use Proxmox VE on my server now. then I can directly get sensor readings from host without network. It is much safer to prevent the server get overheat when the network is down.
I use cron to exec this script every minute.
install ipmitool use your package manager such as apt-get install ipmitool -y
upload the script such as /root/autospeed.sh
chmod +x /root/autospeed.sh
echo "* * * * * root /root/autospeed.sh" | sudo tee -a /etc/crontab
systemctl restart cron
use autospeed.sh, and set variables in the script to make connection.
just use autospeed-host.sh.
