Hello @Christian611
I came across your question -- I'm sorry it wasn't answered sooner.
So, what I'd recommend is using Custom Fields. Specifically, use them in Sites (the cloud-based platform). Create the unique custom field(s) that you need for each Datacenter, Rack, Unit, etc.
Then, instead of a "report", use "Custom Views" to create a live view of your datacenter. You can use the "Advanced Filter" feature to narrow down your specific details.
If you are wanting to create a report based on volume/capacity in your datacenter or racks, you'll need to use some other logic. Instead of using the built-in features, you can use the "code" button to reveal the code, modify with the logic you'd like using Mongo.
I'd think that Custom Fields with an Advanced filter will be easier and quicker to create.
I hope this helps give you a little direction.
