1, four points must be considered in data center construction.
One is the availability and timeliness of data; The second is the size of the data center; Third, the power density of the cabinet (KW/ cabinet); Fourth, meteorological conditions, network and hydropower resources. The selection of any data center system design scheme must be based on the investigation of these contents.
2. Different industries have different design requirements for data center construction.
Such as financial industry and military system, all problems should give way to availability and timeliness; In BAT or telecom room, the attention to energy saving and investment cost is much higher; In supercomputing system, more attention is paid to the high power density of cabinets and the economy of computer room operation. And so on, the design and planning of data center in the future should meet diversified technical requirements, rather than a single model, which puts forward clear directional requirements for designers.
3. Based on this demand, the future data center construction can be designed and planned from four dimensions: reliability, energy saving, economy and maintainability. He believes that the two concepts of energy conservation and environmental protection cannot be confused. From the actual cases he observed, it is found that there is a "disharmony" between energy saving and environmental protection in the construction of data centers in some areas, such as the utilization of water resources in some water-deficient northwest areas.
4. Key indicators for evaluating data center availability.
Including whether there are hidden dangers caused by power outage/flashover of power supply system, air conditioning system failure, battery pack detection failure, input master switch misoperation caused by output short circuit, lightning protection improper design, IGBT rectifier UPS damage caused by power outage of input power grid or switching operation of main ATS switch of power supply system, Whether there are hidden dangers of generator with capacitive load and step load, whether there are hidden dangers of "large earth circulation", "high zero ground voltage" and "corrosive gas" leading to damage of IT equipment or shortened service life.
