It's not about Open-MPI but I know of only one book on the internals of MPI: "Inside the Message Passing Interface: Creating Fast Communication Libraries" by Alexander Supalov.
I found it useful for understanding how MPI libraries are implemented. It is no substitute for spending hours reading source code or discussing implementation details over coffee, but I think it is a useful guide to understand what one sees in the source code of MPICH and Open-MPI.
