Interesting read, on a subject I know pretty well. We will likley have to institute power surchages to our colocation customers soon.
I liked this interesting tidbit from the comments section:
Also the street price for a 20A circuit in a datacenter is $200-$300, while the cost of a megabit is $100 or less. So a rack of servers that requires two power circuits and pushes 3Mbps (not an unusual scenario) costs twice as much in power than in bandwidth.
I’ll write more about this subject soon.
