How oxide cuts data center power consumption in half

> > The power shelf distributes DC power up and down the rack via a bus bar. This eliminates the 70 total AC power supplies found in an equivalent legacy server rack within 32 servers, two top-of-rack switches, and one out-of-band switch, each with two AC power supplies

This creates a single point of failure, trading robustness for efficiency. There's nothing wrong with that, but software/ops might have to accommodate by making the opposite tradeoff. In general, the cost savings advertised by cloud infrastructure should be more holistic.

This isn't even remotely close. Unless all 32 servers have redundant AC power feeds present, you've traded one single point of failure for another single point of failure.

In the event that all 32 servers had redundant AC power feeds, you could just install a pair of redundant DC power feeds.

Is this not standard? I vaguely remember that rack severs typically have two PSUs for this reason.
