What the shared parts are
- Power shelves & PSUs — The rack-mounted power shelves that convert facility AC or DC input into the regulated rail distributed to trays across the rack, built to the Open Rack V3 33 kW-class spec used in rack-scale AI systems.
- Direct-to-chip cold plates — A metal plate with internal microchannels, bonded or clamped directly onto a GPU, CPU, or switch package, that carries coolant across the die to remove heat by conduction rather than airflow.
- 800 V DC architecture & solid-state transformers — An emerging DC power distribution architecture, using 800 V DC in place of the AC busbar and power-shelf approach current racks use, paired with solid-state transformers (SSTs) that could replace multiple stages of conventional AC transformation.
