I’ve never worked with major enterprise or government systems where there’s aging mainframes — the type that get parodied for running COBOL. So, I’m completely ignorant, although fascinated. Are they power hogs? Are they wildly cheap to run? Are they even run as they were back in the day?
Kind of “older”, i guess… the ones I have at work are from 2017. 36 3.5" harddrives being the main power hog. Each server eats around 1.2kW.
