What the shared parts are
- Enclosures — The rack cabinet frame itself — the enclosure that chassis and trays mount into, sold either as a standalone product or built in-house by the rack ODM.
- 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.
- Rear-door heat exchangers — A heat exchanger mounted on the rear door of a server rack that cools exhaust air with chilled water or refrigerant before it leaves the rack, without cooling the chips directly.
- 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.
