> When we started Oxide, the DC bus bar stood as one of the most glaring differences between the rack-scale machines at the hyperscalers and the rack-and-stack servers that the rest of the market was stuck with. That a relatively simple piece of copper was unavailable to commercial buyers

It seems that 0xide was founded in 2019 and Open Compute Project had been specifying dc bus bars for 6 years at that point. People could purchase racks if they wanted, but it seems like, by large, people didn't care enough to go whole hog in on it.

Wonder if the economics have changed or if it's still just neat but won't move the needle.

HP BladeSystem p-series chassis were all DC bus bar powered back in the mid 2000s. You had a power enclosure which provided DC output to one or more chassis in a rack over the bus bar. We were glad to be rid of those blades but it wasn't because of their power configuration.
