alt Hacker NewsThe datacenter I built in 2007 was DC.
Many datacenters I'd been to at that point were already DC.
Didn't think this was that new of a trend in 2026, but also acknowledge I did not visit more than a handful of datacenters since 2007.
It just seemed like a undenyably logical thing to do.
It's obviously not new. ±400VDC architecture was presented at Open Compute last year, which is a fair indicator that the presenter had put it into practice at least 5 years prior to disclosing it. 48VDC distribution within a rack, and 48-to-1V direct regulators for CPUs, were both contributed to OCP 7 years ago, at which point they were both old hat. And 48VDC telco junk is, of course, totally ancient.
