Informative article..."It's the climate, stupid".
Got a laugh out of: "The server racks are nearly silent, and their internal fans whirr almost imperceptibly. The only exceptions are network switches which, Facebook staff notes, are perversely designed by even the biggest firms to vent air out of their sides. As a result, they run loud and hot-and are openly sworn at."
Which says to me that FB staff has no clue how chassis switches are constructed, or they don't like switches with vertically oriented line cards.
nobody puts a chassis switch at the top of a rack... there are several 1u tors orderable with either ftb or btf airflow but, it is a design consideration.
