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.

Figure 1 — Schematic relationship between the EN 50600 series of documents

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 provides a maturity model addressing the facilities, infrastructures and the information

and communication technology (ICT) equipment of the data centre to enable data centre

owners/operators to:
— employ a framework to baseline their data centre design and practices;
— determine the level of maturity applicable to their data centre;

— identify relevant guidance on potential areas of improvement together with the anticipated benefits

to justify the resources required;
— develop an action plan to migrate to higher maturity levels.

The current document focusses on environmental impact (energy management and environmental

sustainability). Other elements might be included in future documents.

NOTE The term “environmental sustainability” is used recognizing that well established treatments of

“sustainability” feature three separate viability objectives (environmental, economic and social). For the purposes

of this document, only elements of environmental viability are considered.

This document supports the wider adoption of recommended practices of other documents in the

EN 50600 series and those of other recognized relevant standards in the area of energy management

and environmental sustainability.

1 Scope

This document provides a maturity model addressing the environmental impact (energy management

and environmental sustainability) of the facilities, infrastructures and the information and communication

technology (ICT) equipment accommodated by the data centre.

NOTE The term “environmental sustainability” is used recognizing that well established treatments of

“sustainability” feature three separate viability objectives (environmental, economic and social). For the purposes

of this document, only elements of environmental viability are considered.

The elements addressed include design, procurement, operation and end-of-life. The achievement of

the Levels of the maturity model are based upon confirmation of the implementation of applicable

practices of CLC/TR 50600-99-1 and CLC/TR 50600-99-2.

4 Concepts of data centre maturity
4.1 Overview

This document describes a 5-level maturity model which separately addresses multiple elements of the

facilities, infrastructures and the information and communication technology (ICT) equipment of the data

centre in relation to their environmental impact (energy management and environmental sustainability).

Other elements may be included in future documents.
It covers design, procurement, operation and end-of-life.
The purpose of the document is to enable data centre owners/operators to:
— employ a framework to baseline their data centre design and practices;
---------------------- Page: 10 ----------------------
SIST-TS CLC/TS 50600-5-1:2022
CLC/TS 50600-5-1:2021 (E)
— determine the level of maturity applicable to their data centre;

— identify relevant guidance on potential areas of improvement together with the anticipated benefits

to justify the resources required;
— develop an action plan to migrate to higher maturity levels.

This document supports the wider adoption of recommended practices of other documents in the

EN 50600 series and those of other recognized relevant standards in the area of energy management

and environmental sustainability.

The maturity model described by this document is applicable to all data centres and recognizes that the

implementation of data centres varies in terms of:

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

b) availability class;
c) security level;
d) physical size;
e) accommodation (mobile, temporary and permanent constructions).

The maturity model also recognizes that the purpose, or business model, of a data centre can prevent

some of the elements to be addressed fully, or in part, by the data centre owner/operator.

For all the above reasons, the maturity model cannot be applied as a comparison of data centres unless

all the factors relating to the data centre were identical.
4.2 Basis of the maturity model

The maturity model is based upon the practices described in CLC/TR 50600-99-1 and

CLC/TR 50600-99-2.
The eight elements addressed by the maturity model are:
a) MANAGEMENT: Management and operational information;
b) INFRASTRUCTURE: Building;
c) INFRASTRUCTURE: Power supply and distribution;
d) INFRASTRUCTURE: Environmental control;
e) ICT: Software;
f) ICT: Compute;
g) ICT: Storage;
h) ICT: Networking.

NOTE Security systems and telecommunications cabling are not addressed in this document.

There are 5 levels applicable to each element with the progression within the model designated Level 1

to Level 5.
4.3 Progress along the Levels of the maturity model
The practices associated with each level are listed in the following clauses.
a) LEVELs 1, 2 and 3: Clause 5;
---------------------- Page: 11 ----------------------
SIST-TS CLC/TS 50600-5-1:2022
CLC/TS 50600-5-1:2021 (E)
b) LEVEL 4: Clause 6;
c) LEVEL 5: Clause 7.

Level 1 for a given element is defined as not meeting 50 % of the applicable practices for that element

specified in Clause 5.

Level 2 for a given element is defined as meeting at least 50 % of the applicable practices for that

element specified in Clause 5.

Level 3 for a given element is defined as meeting 100 % of the applicable practices for that element

specified in Clause 5.

Level 4 for a given element is defined as meeting 100 % of the applicable practices for that element

specified in Clause 6. Level 4 for a specific element cannot be attained unless Level 3 has been

achieved for that element. For elements without practices or applicable practices in Level 4, level 4 is

attained when Level 3 has been achieved for that element.

Level 5 for a given element is defined as meeting the requirements of Clause 7. Level 5 for a specific

element cannot be attained unless Level 3 and Level 4 have been achieved for that element. For

elements without practices or applicable practices in Level 5, Level 5 is attained when Level 3 and Level

4 have been achieved for that element.

For each Level there are practices for data centres in operation and new data centres. New data centres

are those built or refurbished or upgraded from 2021 onwards. For new data centres all practices (new

and operating) are relevant to achieve the Level.
4.4 Reporting of maturity model Levels

The graphical representation shall conform to the layout of Figure 2 (or Figure 3 where certain elements

are of Level 0).

In order for a reported Level to be meaningful, the reporting organization shall provide the following

information:
a) the data centre under inspection
b) the DCMM Level
c) the date of the assessment
4.5 Presentation of the maturity model

For a given data centre, assessment against each element will lead to a documented report which details

the specific items for that element and how they have been accomplished (see 4.4). A graphical

summary of the position of a data centre maturity shall be employed as shown in Figure 2 and Figure 3.

---------------------- Page: 12 ----------------------
SIST-TS CLC/TS 50600-5-1:2022
CLC/TS 50600-5-1:2021 (E)

Figure 2 — Example of the graphical representation of data centre maturity elements

From the information in the example of Figure 2:
a) “Infrastructure: Environmental control” is at Level 5;

b) “Management”, “Infrastructure: Building”, “ICT-Compute” and “ICT: Network” are at Level 4;

c) “Infrastructure: Power supply and distribution” and “ICT: Storage” are at Level 3;

d) “ICT: Software” is at Level 2.

Based upon this information the data centre owner/operator by reference to Clauses 5 and 6 can identify

the practices/actions necessary to improve the elements associated with the lower Levels. An analysis

of the anticipated benefits can then be undertaken and assessed against the resources required to

implement those practices/actions.

However, as indicated in 4.1, certain elements can be beyond the control of the data centre

owner/operator and should be indicated by a Level 0 (meaning not applicable). An example of this is

shown in Figure 3.
---------------------- Page: 13 ----------------------

CLC/TS 50600-5-1:2021 (E)

Figure 3 — Example of the graphical representation of data centre maturity elements

including some of Level 0
From the information in the example of Figure 3:

— "ICT: Network", “Management” and “Infrastructure: Power supply and distribution” are at Level 3;

— “Infrastructure: Building” is at Level 4;
— “Infrastructure: Environmental control” is at Level 5;
— “ICT: Software“, “ICT-Compute” and ”ICT: Storage” are at Level 0.

Level 0 indicates that all the ICT elements are beyond the control of the data centre owner/operator and

no evolution of the maturity model can be expected for these elements.
5 Practices underpinning Levels 1, 2 and 3
5.1 General

Subclause 5.2 contains practices which are relevant to ongoing operation of a data centre.

Subclause 5.3 contains practices which are relevant to the construction of a new build data centre or

the refurbishment or upgrade of an existing data centre.
