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 need to provide modular, scalable and flexible facilities and infrastructures to easily
accommodate the rapidly changing requirements of the market. In addition, energy consumption and
water/resource usage 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
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 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 maturity model for
energy management and environmental sustainability.
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, IT 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.
This document is intended for use by and collaboration between facility managers, ICT managers, and main
contractors.
The inter-relationship of the documents within the EN 50600 series is shown in Figure 1.

Figure 1 — Schematic relationship between the EN 50600 series of documents
EN 50600-1 introduces the general concepts relevant for the design and operation of data centres.
EN 50600-2 documents define the requirements for the data centre design and 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 50600-3-1 specifies requirements and recommendations for data centre operations, processes and
management.
EN 50600-4 documents specify requirements and recommendations for key performance indicators (KPIs)
used to assess and improve the resource usage efficiency and effectiveness, respectively, and criteria of
resilience of a data centre.
CLC/TS 50600-5-1 specifies the maturity model for energy management and environmental sustainability
and refers amongst others to EN 50600-4-X for KPIs as appropriate.
This document addresses the operational and management information (in accordance with the
requirements of EN 50600-1). A data centre’s primary function typically is to house large quantities of
computer and telecommunications hardware which affects the construction, operation, and physical security.
Most of the data centres may impose special security requirements. Therefore, it is important that the
planning of a data centre by the designer and the various engineering disciplines that will assist in the
planning and implementation of the design of the data centre i.e. electrical, mechanical, security, etc. are
carried out in cooperation with the IT and telecommunications personnel, network professionals, the facilities
manager, the IT end users, and any other personnel involved.
Figure 2 shows an overview of the document:
• The organization provides the data centre strategy and resources for data centre management and
operation.
• Data Centre management organizes all process and resources for data centre operation.
• Operational information and documentation support all data centre activities.

Figure 2 — Data centre management overview
The transition from planning and building to operation of a data centre is considered as part of the
acceptance test process in 8.3.
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 specifies processes for the management and operation of data centres. The primary focus of
this document is the processes necessary to deliver the expected level of resilience, availability, risk
management, risk mitigation, capacity planning, security and resource and energy efficiency.
The secondary focus is on organization and data centre management to align the actual and future
demands. Only processes specific for data centres are in the scope of this document.
Business processes like people management, financial management, etc. are out of scope.

d) an environmental control policy (see 8.2);
e) an asset management policy (see 8.4);
f) a monitored PUE KPI (see 9.5);
g) a lifecycle management policy (see 9.6).
5 Data centre strategy
5.1 Purpose
A data centre strategy shall be defined by the owner and reflect the requirements of the stakeholders. The
data centre strategy shall describe the following aspects, but not limited to:
a) availability and resilience;
b) physical security;
c) energy and resource efficiency;
d) maintainability;
e) governance.
At the beginning of the initial planning of a data centre there is a clear idea of the owner about the needs the
data centre shall serve and the identified stakeholders that are relevant to the operation. During the long
lifetime of a data centre, the needs will change and thus the strategy of operation. Power density, cooling
strategy and even the desired level of resilience can change during a data centre’s lifetime due to new
technologies in IT and facility. Also the level of desired operational maturity (see Table A.2) can change
according to the needs of users and owners.
Data centre strategy aims to align the actual capabilities and future demands of data centre’s users and
owners. Actual capabilities are reflected in data centre’s implemented processes and KPI. Future demands
can be derived from a business and IT strategy of the owners or the users. In addition, expectations for the
data centre service market can give input to a strategy alignment. It can be quite a complex process of
customer questionnaire and market observation to create a strategy based on valid assumptions.
Figure 3 shows an example of key elements of a data centre strategy.

5.2 Activities
5.2.1 Assess current capabilities
Current activities shall be evaluated and shall be documented in a report, e.g. Business Organization Report,
Operational Management Report and Environmental Management Plan (see CLC/TS 50600-5-1 for further
details).
For every process implemented a set of KPI or an internal audit should be used to assess the quality of the
process execution. Processes with poor performance shall be inspected for lack of resources, insufficient
interaction with other processes or organizational resistance. Processes with lower management attention
will usually deliver lower results. Operational excellence should be developed by raising attention to new
processes while keeping high process quality at the existing processes.
5.2.2 Implement processes and KPI
Processes shall be implemented and documented for the operation and management of data centres in
accordance with this document. The documentation shall contain a register of all implemented processes
which contains the defined scope, objectives and responsibilities of the processes.
As operational excellence maturity and resources allow, additional processes can be implemented as a part
of the Data Centre Strategy. The organization shall be able to follow the Data Centre Strategy to accept the
value of the new processes; otherwise organizational resistance will be more likely than process quality.
For existing processes it can be useful to step forward in KPI for quality assessment. Once the process is
implemented and delivers an acceptable quality, continuous i
