In our previous post, we started a conversation about the topic of DC power distribution and 48v DC power in the data center.  The struggle to improve efficiency within computing facilities began long before the chipset had been invented, back in the ‘war of the currents’ in the 1880s.

While we touched on the topic in this 2017 blog, we wanted to spend a little more time exploring the concept of DC (or direct current) power distribution in the data center.  For years, it has been an esoteric blip on the radar of critical power distribution, hovering just outside the realm of ‘interested, just not today.’  We would like to revisit the topic because a strange thing has been happening—quietly, mind you--over the last couple of years:  designers and large data center operators are actually starting to implement solutions that utilize DC power.
