BS EN 50600-2-2:2014 EN 50600-2-2:2014Introduction The unrestricted access to internet-based information demanded by the information society has led to an exponential growth of both interne
21、t 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 network operators (delivering those services to customer prem
22、ises) 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 consumption of data centres has become critical both from an
23、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, co-hosting, or network operator facilities); b) securit
24、y 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 and objectives influence the design of data centres in
25、 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 Standards specifies requirements and recommendations to s
26、upport 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 managers, project managers, main contractors; 2) consultants,
27、 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 comprise the following standards: EN 50600-1: In
28、formation technology Data centre facilities and infrastructures Part 1: General concepts; EN 50600-2-1: Information technology Data centre facilities and infrastructures Part 2-1: Building construction; EN 50600-2-2: Information technology Data centre facilities and infrastructures Part 2-2: Power d

32、tionship between the EN 50600 standards EN 50600-2-X standards specify requirements and recommendations for particular facilities and infrastructures to support the relevant classification for “availability”, “physical security” and “energy efficiency enablement” selected from EN 50600-1. This Europ
33、ean Standard addresses facilities and infrastructures for power supplies to, and power distribution within, data centres together with the interfaces for monitoring the performance of those facilities and infrastructures in line with EN 50600-2-6 (in accordance with the requirements of EN 50600-1).
34、The line diagrams used in certain figures are not intended to replace the more familiar electrical circuit diagrams associated with power supply and distribution systems which are included where relevant. This European Standard is intended for use by and collaboration between architects, building de
35、signers and builders, system and installation designers. This series of European Standards does not address the selection of information technology and network telecommunications equipment, software and associated configuration issues. BS EN 50600-2-2:2014 EN 50600-2-2:20141 Scope This European Stan
36、dard addresses power supplies to, and power distribution within, data centres based upon the criteria and classifications for “availability”, “physical security” and “energy efficiency enablement” within EN 50600-1. This European Standard specifies requirements and recommendations for the following:
37、 a) power supplies to data centres; b) power distribution systems within data centres; c) facilities for both normal and emergency lighting; d) equipotential bonding and earthing; e) lightning protection; f) devices for the measurement of the power consumption characteristics at points along the pow
38、er distribution system and their integration within management tools. 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 assista
39、nce in meeting these standards and regulations. Conformance of data centres to the present document is covered in Clause 4. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
