What the shared parts are
- DCIM, digital twins, capacity planning — Software that models a data center's power, cooling, space, and asset capacity in a live digital twin, giving operators visibility into what a facility can still support.
- Building management, controls, environmental sensors — The building management system, PLCs, and environmental sensors that monitor and automatically control chillers, air handlers, pumps, and dampers across the facility.
- MV switchgear, E-houses, power skids — Medium-voltage switchgear packaged into pre-fabricated electrical houses (E-houses) or skids that distribute power across a campus and can be factory-built and shipped as modules.
- Busway / busbar trunking — Rigid, modular busbar systems that carry power along a data hall's overhead or perimeter path with tap-off points, used as an alternative to running individual cables to each row.
