What the shared parts are
- 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.
- 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.
- Floor PDUs, RPPs, static transfer switches, ATS — Floor-mounted power distribution units, remote power panels, and the static and automatic transfer switches that route power between utility, UPS, and generator sources down to the rack level.
- UPS (static, modular, rotary/DRUPS) & UPS power semis — Uninterruptible power supplies that bridge the gap between a utility outage and generator start, built as static (battery-based), modular, or rotary/diesel-rotary (DRUPS) designs, plus the power semiconductors inside them.
