Hey,
So I found a new toy to play around with: RackTables.
The purpose of this software is to help you organize your IT equipment, including servers, switches, routers, patch panels into visual racks.

It gives you the option to define objects, where each object has pretty much all the properties there are: hardware, software, NICs, MACs, IPs, ports, KVM and so on. You can define IP pools you have and set the IPs of the servers accordingly. You can connect the ports of the switches/patch panels to the servers, and do the same with KVMs.

Basically, it really gives you the option to enter it all into the database and give you the visual of any of your equipment via the Web GUI.
The software is really simple. And the only hassle is to actually put it all in.
The installation is described on the website and is done in 5 minutes.

The only thing it will not you do is visual diagram of your network, but there are other applications for that.

A must for IT folks.
Have fun!
