tier 4 datacenter requirement "translation"
Datacenter owner/operator and retired engineering contractor here.
They are not talking about â??mechanicalâ?? systems such as HVAC, they are instead describing a â??Mechanically attached roofing systemâ??. Thatâ??s a specific term, and covers metal roofs of a specific type and construction.
Concrete is a superior substitute. Concrete deck your datacenter and youâ??re done. Itâ??s considered pretty bulletproof. Figuratively and literally.
Our DCs have concrete floors walls and ceilings.
