What is the difference between the construction standard of Class A engine room and the construction of Class B engine room?

The construction of the computer room is a systematic project. It must be based on the needs of the work, people-oriented, meet the functional needs, take into account the beauty and practicality, provide a safe and safe space for the equipment, and create a good working environment for the staff engaged in computer operation.
Class A standard
Class A is fault-tolerant. The equipment in the equipment room of Class A electronic information system shall be configured according to the fault-tolerant system. During the operation of the electronic information system, the equipment of the site shall not be caused by operational errors, equipment failure, external power interruption, maintenance and overhaul. The information system was interrupted.
Application case: National Meteorological Observatory, National Information Center, Computing Center: important military command department, airport, radio station, TV station, emergency command center of large and medium-sized cities: bank head office, national and regional power dispatch center, etc. Important control room.
Class B standard
Class B is redundant. The equipment in the equipment room of the Class B electronic information system shall be configured according to the redundancy requirements. During the operation of the system, the equipment of the site shall be within the redundancy capability, and the operation of the electronic information system shall not be interrupted due to equipment failure. .
Application case: Research institutes: institutions of higher learning, tertiary hospitals: Meteorological observatories, information centers, disease prevention and control centers, power dispatch centers, traffic (rail, highway, water transport) command and dispatch centers in large and medium-sized cities: International Conference Center: Large museums, archives, convention centers, international sports competition venues: government office buildings at the provincial and ministerial level; electronic information system rooms and important control rooms for large industrial and mining enterprises.


According to China's "Electronic Information System Computer Room Design Specification" (GB 50174-2008), the data center can be economically and socially damaged or affected according to the nature of use, management requirements and the interruption of the operation of the electronic information system due to site equipment failure. It is the third level of A, B and C.
Class A is fault-tolerant. During the operation of the system, the equipment of the site should not be interrupted due to operational errors, equipment failure, external power interruption, maintenance and overhaul.
Class B is redundant. During the period when the system needs to operate, its site equipment is within the redundancy capability, and the electronic information system should not be interrupted due to equipment failure.
Class C is the basic type. Under the normal operation of the site equipment, the operation of the electronic information system should be guaranteed.
Internationally, the data center is divided into four levels according to the uptime supported by the data center. According to different levels, the requirements for the facilities in the data center will also be different. The higher the level requirements, the stricter the level 1 is the most basic configuration, there is no redundancy, and the level 4 provides the fault tolerance rate of the high level of Zui. The four different levels of definition include different requirements for building structure, telecommunications infrastructure, safety, electrical, grounding, mechanical and fire protection.

RDP

Re-dispersible Polymer Powder, based on vinyl acetate-ethylene(EVA)emulsion, produced by-spray drying to obtain a free flowing organic polymer powder. it can re-disperse in water and form a film after water evaporation by coalescence of individual polymer particles. The film acts as an organic binder to glue together different substrates, reinforce mortar structure and provide excellent adhesion at cement or gypsum based dry mixed mortar substrate interface.
