I manage hundreds of servers at work. They each have a BMC (remote power on/off, reset, KVM, etc) and we need to use those features frequently. I've been using a Google Docs spreadsheet to track their URLs, what each box is used for, specs, etc but it feels like a dynamic web app would be better for this purpose. Does anyone use anything like this? Did you make your own?
There are inventory programs, many of them, that will handle keeping system information updated.
I am posting to say that I tend to set the IPs to match with a known offset.
For example:
192.168.5.12 is the host.
192.168.105.12 is the BMC.
A wiki is the great for documentation of use, links, and files.
