eshell is the "Emacs shell" for a reason :-)

Commands like cd interpret file names like somewhere else in Emacs. "/"
is the local root, and "cd /" changes to that directory. You can also
fire commands like "cd /ssh:host:/", even if your current directory is
not related to that host. This works even if your current directory
points to another remote host.

If you want to use the system's cd command, you might use "*cd /". The
leading star disables the eshell builtins.

All of this is described in the eshell manual. Try (info "(eshell) Built-ins")
