Rack Level Infrastructure: Power Delivery - Line hint:

Context Before
Since the deployment of GB200, the main theme of the power delivery infrastructure evolution has been about transmission efficiency and power stability.
Evidence
Hyperscalers are developing power delivery infrastructure to address the challenges that comes with high density AI server racks with the roadmap set to 1MW per rack in the next couple of years.
Context After
Hence, HVDC (high voltage direct current) power rack, BBU (battery back up units), CBU (capacitor backup units), liquid cooled busbar, and SST (solid state transformers) are being developed to increase transmission efficiency and power stability. These will be deployed by customers depending on their proprietary infrastructure designs.
② Atomic Claim
Hyperscalers 正在開發 power delivery infrastructure，以因應 high-density AI server racks 的挑戰；roadmap 指向未來幾年每 rack 1MW。
