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?
Look into getting a CMDB and keep track of all of your hardware. That can store the hostname / IPs of your KVM / OS or virtualization layer, vkernels, storage adapter IPs, your vCenters and so on and so forth. If your data is getting so big that spreadsheets are getting tough to manage, then you probable need a more enterprise method of storing it.
