What the shared parts are
- Rack PDUs — The power distribution units mounted in or beside a rack that meter and distribute power to individual devices, sitting between facility power and the rack's internal busbar or whips.
- Coolant distribution units — The unit that separates the IT-side (technology) coolant loop from the facility water loop, exchanging heat between them and pumping and filtering the technology-side flow — sized from in-rack and in-row units up to multi-megawatt facility-class units.
- Prefab / modular data centers & power/cooling skids — Factory-built modular data center units and prefabricated power and cooling skids that are assembled off-site and installed as complete, pre-integrated blocks.
