Introduction
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 equipment 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 usually 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 environmental point of view (reduction of environmental
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) 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 and objectives influence the design of data centres in
terms of building construction, power distribution, environmental control, telecommunications cabling
and physical security as well as the operation of the data centre. Effective management and operational
information is important in order to monitor achievement of the defined needs and objectives.
Recognizing the substantial resource consumption, particularly of energy, of larger data centres, it is
also important to provide tools for the assessment of that consumption both in terms of overall value
and of source mix and to provide Key Performance Indicators (KPIs) to evaluate trends and drive
performance improvements.
At the time of publication of this document, the EN 50600 series is designed as a framework of
standards, technical specifications and technical reports covering the design, the operation and
management, the key performance indicators for energy efficient operation of the data centre as well as
a data centre maturity model.
The EN 50600-2 series defines the requirements for the data centre design.
The EN 50600-3 series defines the requirements for the operation and the management of the data
centre.
The EN 50600-4 series defines the key performance indicators for the data centre.
The CLC/TS 50600-5 series defines the data centre maturity model requirements and
recommendations.
The CLC/TR 50600-99-X Technical Reports cover recommended practices and guidance for specific
topics around data centre operation and design.
This series of documents 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, operators, facility managers, ICT managers, project managers, main contractors;
2) consulting engineers, architects, building designers and builders, system and installation designers,
auditors, test and commissioning agents;
3) facility and infrastructure integrators, suppliers of equipment;
4) installers, maintainers.
At the time of publication of this document, EN 50600 series will comprise the following standards and
documents:
EN 50600-1, Information technology — Data centre facilities and infrastructures — Part 1: General
concepts
EN 50600
