The generic bill of materials
Whatever the vendor list, a facility like this contains the same part categories:rack-scale systems, direct-to-chip cold plates, coolant distribution units, large power transformers (345–765 kV) & substations, UPS (static, modular, rotary/DRUPS) & UPS power semis, backup generation: gensets, fuel systems, HVO, chillers & compressors — the full set is in the scales matrix.
