About The Project

This project allows you to automatically control your Dell PowerEdge fan speeds using IPMI tools determined by a customisable temperature range.

Getting Started

Prerequisites

Python 3.8
Python pip3
IPMI Tools (https://github.com/ipmitool/ipmitool)

Installation (local)

After installing the projects prerequisites, you will need to install the projects python dependencies using pip3

Install Python dependencies using pip3
```
pip3 install -r requirements.txt
```

Environment variables

This project depends on several environment variables being available to the script, these are described below

Variable	Default	Description
`IDRAC_HOST`	`null`	IP address of your iDRAC host
`IDRAC_USERNAME`	`null`	Username of your iDRAC host
`IDRAC_PASSWORD`	`null`	Password of your iDRAC host
`TEMP_RANGES`	`null`	Pipe-separated list of temperature ranges, see below for more details

Temperature ranges

The temperature ranges environment variable allows you to define a range of temperatures and your desired fan speed (as a percentage). This is set using a pipe-separated string provided as an environment variable (TEMP_RANGES).

Format:
[start of range], [end of range], [fan speed percentage]|[start of range], [end of range], [fan speed percentage]

For example:
30, 40, 5|40, 45, 8|45, 50, 10|50, 55, 20|55, 100, static

This will be parsed as:

Temperature	Fan speed
30c to 40c	5%
40c to 45c	8%
45c to 50c	10%
50c to 55c	20%
55c to 100c	static

static fan speed mode will turn off manual fan control and allow iDRAC to determine what speed the fans should be for the current temperature (default behaviour).

If there isn't a temperature range configured, this tool will use the closest temperature range based on the highest temperature sensor.

Usage (local)

To run the project locally, execute the controller.py file

python3 controller.py

Usage (Docker)

You can run this project using docker by pulling and running the pre-build image using the following command

docker run -d \
  --name iDRAC_IPMI_fan_controller \
  --restart=unless-stopped \
  -e IDRAC_HOST=<iDRAC host> \
  -e IDRAC_USERNAME=<iDRAC username> \
  -e IDRAC_PASSWORD=<iDRAC password> \
  -e TEMP_RANGES=<pipe seperated list of temp ranges> \
