I have often diagrammed rack and cabinet layouts and elevations using Visio linked to a database or Excel tables. There is a Rack Diagram template in Visio which is great for manually creating cabinet elevations manually, but there is nothing currently out of the box to automate this process, so it can be a laborious task unless you have some custom code. It is quite simple to draw a computer room layout of the racks and cabinets and to link each one to a row of data. In this article, I have a table of rack equipment in Excel, and used PowerQuery in PowerBI to summarize these rows for each data center, rack and U height position, since there are sometimes more than one item of equipment per U height. In this example, I have color coded the criticality of each equipment such that the most important display as red, and the least important as green. This means that a PowerBI user can quickly see where the critical racks, U heights and equipment are. Of course, I could have used any metric, such as power consumption, heat output or humidity, for the colour-coding. It all depends on the data available, and the audience for the report.
