Yesterday I visited Data center,There, Many servers are running,Security is very high, they don't allow without capturing our photo.,Server room Temperature is 18 degrees C. It dose not contain any chairs,We need to sit on the floor.
Its a great chance for me to visit the server room as a developer. I stayed 2 hours in that room. Lot of sound will come from servers. Server racks are connected serially.
