An anonymous reader wonders: "I'm curious as to what tools Slashdot readers use to inventory and document their networks? What got me thinking about this is the part VMWare has been taking in data centers. You've got your SAN, various physical and logical networks, various VMs, and so forth. It just adds a new layer of complexity in terms of documentation. I'm curious as to what people have been using as for doing things like documenting how their backups work, LAN settings, FW settings, where and what runs what services, and so forth. How do you blueprint your entire IT infrastructure so that someone brand new could start and figure out what does what?"
