19、ction The unrestricted access to internet-based information demanded by the information 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 equipme
20、nt for data processing, data storage and data transport. They are required both by network 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 easil
21、y accommodate the rapidly changing requirements of the market. In addition, energy consumption 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
22、 implementation of data centres varies in terms of: a) purpose (enterprise, co-location, 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
23、service, the provision of security and the objectives for energy efficiency. These needs 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 require
24、d to monitor achievement of the defined needs and objectives. This series of European Standards specifies requirements and recommendations to support the various parties involved in the design, planning, procurement, integration, installation, operation and maintenance of facilities and infrastructu
25、res within data centres. These parties include: 1) owners, facility managers, ICT managers, project managers, main contractors; 2) architects, building designers and builders, system and installation designers; 3) facility and infrastructure integrators, suppliers of equipment; 4) installers, mainta
26、iners. At the time of publication of this European Standard, the EN 50600 series will comprise the following standards: EN 50600-1, Information technology Data centre facilities and infrastructures Part 1: General concepts; EN 50600-2-1, Information technology Data centre facilities and infrastructu

30、r facilities and infrastructures to support the relevant classification for “availability”, “physical security” and “energy efficiency enablement” selected from EN 50600-1. This European Standard addresses the environmental control facilities and infrastructure within data centres together with the
31、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). This series of European Standards does not address the selection of information technology and network telecommunications equipment, softwa
32、re and associated configuration issues. BS EN 50600-2-3:2014 7 EN 50600-2-3:2014 1 Scope This European Standard addresses environmental control within data centres based upon the criteria and classifications for “availability”, “security” and “energy efficiency enablement” within EN 50600-1. This Eu
33、ropean Standard specifies requirements and recommendations for the following: a) temperature control, b) fluid movement control, c) relative humidity control, d) particulate control, e) vibration, f) floor layout and equipment locations, g) energy saving practices, h) physical security of environmen

Excessive variations of temperature or relative humidity c
48、an directly affect the functional capability of the data centre and its infrastructures. The functional elements of the environmental control system are divided into primary and secondary elements. Primary elements relate to the mechanical generation of temperature controlled fluids. Secondary eleme
49、nts relate to the distribution of fluids generated by the primary elements. See Table 1 for examples of these elements. Some environmental systems combine the function of primary and secondary elements.
