@Fiona At work, we mostly use function + year-entered-service or function + ordinal for things that exist in multiple instances. Our AFS file servers are named after maritime disasters (mostly oil spills these days). We used to use cartoon characters, and there were a series of login servers named after the characters in Scooby-Doo. Personal machines are named after either horses in Robin McKinley's Damar books or swords in Diane Duane's Middle Kingdoms books.
