> > 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.

Look very carefully at the picture of the rack at https://oxide.computer/ :) there are two power shelves in the middle, not one.

We're absolutely aware of the tradeoffs here and have made quite considered decisions!
