Fan Control program for Dell servers

Another Dell IPMI Fan Control Script, 5 settings, both ESXI and Linux hosts Service scritps for either systemd or SysV

WARNING - Temp ranges are specific to the TDP of my CPU

          Please go to intel ARK for your CPU and check the 

          TDP (Thermal Design Power) 

          then subtract about 20-10 degrees C for returntoauto

          this allows the BIOS to manage high temps

          tested on R630 with e5-2697a V4

          Monitor the temps and speeds to fine tune your system

          on systemd just use journalctl -t fanctl to see what temp changes are triggered

Still in progress - here is what is completed and works

Features

• Two versions, one for running directly on ESXI server and one for any linux host/guest
• Exapnd to 5 temp settings
• Retuturn to BIOS DELL BIOS/IPMI control when a threashold is reached
• ESXI specifc INIT file for stop/start/status/reload
• Output goes to syslog
• aded PID file
• Temp, ID, Server and other parms in a json file
• init script for systemd
• PEP 8 style guide

Requirements

• Must have IPMITOOL installed
  ubuntu/debian apt install ipmitool -y
  ESXI - must find and install ipmitool vib and install. usaly in /opt/ipmitool
  PIP is not required, using standard python libaries

Usage

Modify the use paramters in the .py file

Linux

 Manualy just run fanctl.py to test (python3 ./fancctl.py)

Systemd - Setup as a service

DO NOT USE rc.local if your system is systemd, upgrade to current stack

Install fanctl.service to /etc/systemd/service

Install fanctl.py /root or anywhere you want to place this script

If you chagned the install from /root, then update the fanctl.service to correct location

Reload the service files to include the new service.

    sudo systemctl daemon-reload

Start your service

    sudo systemctl start your-service.service
To check the status of your service

    sudo systemctl status example.service
To enable your service on every reboot

    sudo systemctl enable example.service

Modify the after section to a servcie you want to start after. This is setup for Proxmox ()

ESXI

Put both esxifanctl.py and fanctlinit.sh int the same directory (maybe /opt/fanctl)
chmod +x fanctlinit.sh esxifanctl.py
./fanctl start

SysV - old school

Install fanctlinit.sh to /etc/rc.local

Output of program

All output is directed to syslog or syslog.log (esxi)
