I really envy folk that love DC for networking gear :-).Work in 2007 was an all-DC network. I rebuilt it into AC, considering the ISP also owned the data centre (most of whose customers bought AC). The space we freed up and the ease of deployment was night & day.
Currently, we obviously need DC for the terrestrial Transport and wet plants (because that's just how classic telco rolls), but I also switched all IP/MPLS gear to AC soon as I arrived. Heck, even the Arbor (now Netscout) gear, as well as the HP server rack, was loaded with DC power supplies. Those things just had to go.
There is an avenue of pleasure in not having to spend inordinate amounts of time adding major electrical planning to deploying/decommissioning a router, switch or server.
But yeah, I know the AC vs. DC discussion can become a rat hole.I'm aware of data centre operators now providing DC as an option for their expansion projects, when they previously had it as the norm, FWIW.
