BS EN 50600-2-4:2015EN 50600-2-4:2015 6 Introduction The unrestricted access to internet-based information demanded by the information

26、society has led to an exponential growth of both internet traffic and the volume of stored/retrieved data. Data centres are housing and supporting the information technology and network telecommunications equipment for data processing, data storage and data transport. They are required both by netwo

27、rk operators (delivering those services to customer premises) and by enterprises within those customer premises. Data centres need to provide modular, scalable and flexible facilities and infrastructures to easily accommodate the rapidly changing requirements of the market. In addition, energy consu

28、mption of data centres has become critical both from an environmental point of view (reduction of carbon footprint) and with respect to economical considerations (cost of energy) for the data centre operator. The implementation of data centres varies in terms of: a) purpose (enterprise, co-location,

29、 co-hosting or network operator facilities); b) security level; c) physical size; d) accommodation (mobile, temporary and permanent constructions). The needs of data centres also vary in terms of availability of service, the provision of security and the objectives for energy efficiency. These needs

30、 and objectives influence the design of data centres in terms of building construction, power distribution, environmental control and physical security. Effective management and operational information is required to monitor achievement of the defined needs and objectives. This series of European St

31、andards specifies requirements and recommendations to support the various parties involved in the design, planning, procurement, integration, installation, operation and maintenance of facilities and infrastructures within data centres. These parties include: 1) owners, facility managers, ICT manage

32、rs, project managers, main contractors; 2) architects, building designers and builders, system and installation designers; 3) facility and infrastructure integrators, suppliers of equipment; 4) installers, maintainers. At the time of publication of this European Standard, EN 50600 series will compri

This European Standard addresses the specific requirements for the telecommunications cabling infrastructure in data centres used for

39、 the purpose of IT networking and building services (in accordance with the requirements of EN 50600-1). This European Standard is intended for use by and collaboration between architects, building designers and builders, system and installation designers. This series of European Standards does not

41、sed upon the criteria and classifications for “availability” within EN 50600-1. This European Standard specifies requirements and recommendations for the following: a) information technology and network telecommunications cabling (e.g. SAN and LAN); b) general information technology cabling to suppo

42、rt the operation of the data centre; c) telecommunications cabling to monitor and control, as appropriate, power distribution, environmental control and physical security of the data centre; d) other building automation cabling; e) pathways, spaces and enclosures for the telecommunications cabling i

43、nfrastructures. Safety and electromagnetic compatibility (EMC) requirements are outside the scope of this European Standard and are covered by other standards and regulations. However, information given in this European Standard may be of assistance in meeting these standards and regulations. 2 Norm
