Mot clear to me what "data center compatibility" for a PDP-11 means.

Anyhow, the BeagleBone runs Debian Linux, has an Ethernet port and the 
emulation software is a plain Linux application.
So all emulator binaries and all PDP-11 disk images or other data can 
reside anwhere in the world and are not bound to the UniBone SDcard.
