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 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 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:

purpose (enterprise, co-location, co-hosting or network operator facilities);
security level;
physical size;
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 required 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 European Standard, EN 50600 series is designed as a framework of standards and technical reports covering the design, the operation and management as well as the key performance indicators for energy efficient operation of the data centre.

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/TR 50600‑99‑X Technical Reports cover recommended practices and guidance for specific topics around data centre operation and design.

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 infrastructures within data centres. These parties include:

owners, operators, facility managers, IT managers, project managers, main contractors;
consulting engineers, architects, building designers and builders, system and installation designers, auditors, test and commissioning agents;
facility and infrastructure integrators, suppliers of equipment;
installers, maintainers.

At the time of publication of this European Standard, the EN 50600‑2 series comprises the following standards:

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 supply and distribution;

EN 50600‑2‑3, Information technology — Data centre facilities and infrastructures — Part 2-3: Environmental control;

EN 50600‑2‑4, Information technology — Data centre facilities and infrastructures — Part 2-4: Telecommunications cabling infrastructure;

EN 50600‑2‑5, Information technology — Data centre facilities and infrastructures — Part 2-5: Security systems;

The inter-relationship of the standards within the EN 50600 series is shown in Figure 1.

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.

EN 50600‑3‑X documents specify requirements and recommendations for data centre operations, processes and management.

EN 50600‑4‑X documents specify requirements and recommendations for key performance indicators (KPIs) used to assess and improve the resource usage efficiency and effectiveness, respectively, of a data centre.

This European Standard addresses the environmental control facilities and infrastructure within data centres together with the interfaces for monitoring the performance of those facilities and infrastructures in line with EN 50600‑3‑1 (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 address the selection of information technology and network telecommunications equipment, software and associated configuration issues.

1 Scope

This document addresses environmental control within data centres based upon the criteria and classifications for “availability”, “security” and “energy efficiency enablement” within EN 50600‑1.

This document specifies requirements and recommendations for the following:

temperature control;
fluid movement control;
relative humidity control;
particulate control;
vibration;
physical security of environmental control systems.

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.
