Data center architecture for Bare Meal servers

[harshadineth]

Which Network Architecture would you recommend to a Data Center with only Bare Meal servers and why?

I got this question in an interview. Can someone tell me the answer for it.

 It is a trick question:  It is not a question of "who" but, rather, a question of "do you know what the meaning of a bare-metal server is and do YOU, the candidate, know what it takes to put it into production".
