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:

purpose (enterprise, co-location, co-hosting, or network operator);
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 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:

owners, operators, facility managers, ICT 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 document, the EN 50600‑2 series comprises the following documents:

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;

CLC/TS 50600‑2‑10, Information technology — Data centre facilities and infrastructures — Part 2-10: Earthquake risk and impact analysis;

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

EN 50600‑2‑X documents 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 document addresses the physical security of 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 document is intended for use by and collaboration between architects, building designers and builders, system and installation designers and security managers among others.

This series of documents does not address the selection of information technology and network telecommunications equipment, software and associated configuration issues.

1 Scope

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

This document provides designations for the data centres spaces defined in EN 50600‑1.

This document specifies requirements and recommendations for those data centre spaces, and the systems employed within those spaces, in relation to protection against:

unauthorized access addressing organizational and technological solutions;
intrusion;
fire events igniting within data centres spaces;
environmental events (other than fire) within the data centre spaces which would affect the defined level of protection;
environmental events outside the data centre spaces which would affect the defined level of protection.
NOTE Constructional requirements and recommendations are provided by reference to EN 50600‑2‑1.

Safety and electromagnetic compatibility (EMC) requirements are outside the scope of this document and are covered by other standards and regulations. However, the information given in this document can be of assistance in meeting these standards and regulations.
