Concept Managing server fan speed is crucial for maintaining an optimal balance between cooling efficiency and noise levels, especially in environments where temperature control and acoustics are important. Dell servers, like many other enterprise-grade hardware, come equipped with Intelligent Platform Management Interface (IPMI) capabilities. With the help of ipmi-tools, we can access and control various hardware components of the server, including fan speed, remotely or locally, without needing direct access to the operating system. ...

Context This project has been a culmination of a few projects coalescing together at the same time: I’ve been wanting to play with Cloud-Init in a local environment for a little while now, and I’ve been finding myself spinning up more and more VMs to test some networking automation.
