Provided that whatever mechanisms needed are in place for the actual code in a system to be deployed to, live on, connect to, and use the various physical components that relate to the logical components, and that any physical architecture constraints are accounted for, little more information is generally needed, so where any given component lives just isn't as important from that perspective. That often means that a physical architecture breakdown is at best a nice-to-have item, or maybe a should-have at most.
