Unifi 2.5Gbps Homelab 9U Mini Rack

# Unifi 2.5Gbps Homelab 9U Mini Rack


## Motivation

This mini rack serves two main purposes:
1. running PoE APs and cameras
2. running the 4x Rpi4 cluster with PoE and M.2 hats.

This has been a long term and ongoing project starting in 2019. An [earlier iteration writeup](https://www.nth.io/luke/projects/raspberrypi-homelab/) is available on my blog explaining more of the motivation and specifics to the Pi cluster. Cluster Ansible roles and provisioning can be browsed here:

## Components

The entire rack is fed from one power cable and one coax cable, excluding the ethernet drops, of course.
