Introduction
Energy costs continue to rise, a trend that will continue in the future, while broadband penetration is introducing new
active equipment to the network architecture. In this context, and to reflect other environmental aspects of
sustainability, it is vital that the main telecommunication actors implement effective general engineering of fixed and
mobile broadband networks and sites provisioning, managing or using those networks (i.e. operator sites, operator data
centres and customer data centres) in order to respond to critical issues of energy consumption while proposing essential
solutions to true broadband deployment.
These issues are of particular importance in data centres - both of operators and customers. To guide this process, it is
essential that metrics are defined, termed Global Key Performance Indicators (KPI ) that enable energy usage to be
EM
managed more efficiently.
The ES 205 200 series of standards comprises:
• ES 205 200-1: a generic requirements document addressing Global KPIs for operational infrastructures.
NOTE: Global KPIs do not address design/operation of components or subsystems of broadband deployment
networks.
• A sub-series ES 205 200-2 that defines the Global KPIs, and drives energy management targets, for specific
operational networks and sites and which describes how the Global KPIs are to be applied (which may be used
to support future regulatory objectives):
- ES 205 200-2-1: Data centres;
- ES 205 200-2-3: Mobile access networks.
These documents do not define KPI limits or targets (which is outside the scope of the ES 205 200 series of
standards).
These documents will accelerate:
• availability of operational infrastructure architectures and network implementations that use energy more
efficiently;
• the definition and attainment of sustainability objectives for operational broadband networks.
Within the present document:
• clause 4 explains the definition of a data centre in terms of the systems it comprises and the boundaries that
apply and shows that the present document is equally applicable to operator data centres, operator sites and
customers data centres;
• clause 5 describes how the Objective KPIs of the present document meet the requirements of
ES 205 200-1 [2];
• clause 6 describes the specific requirements of the Global KPI and the supporting Objective KPIs for data
centres;
• annex A discusses the roles of different types of Key Performance Indicators i.e. Technical, Objective and
Global in relation to the overall energy management concepts of the present document.

NOTE: Not all the terms and abbreviations of Figure 1 are included in clause 3 of the present document.
Figure 1: Schematic of core network together with fixed and mobile access infrastructures
With reference to Figure 1:
• an operator data centre (ODC) accommodates a mixture of information technology equipment (ITE) and
network telecommunication equipment (NTE);
• an operator site (OS) will also accommodate a mixture of ITE and NTE - where the NTE may provide
connections to connections to core, fixed access, terrestrial mobile access and satellite mobile access network
infrastructures.
It is unlikely that either the ODC or OS of Figure 1 would allow separate assessment of energy consumption of the ITE
and the various NTE for the disparate network infrastructures. As a result, the boundaries applied to ODC and OS in
relation to the objective of Global KPIs for operational infrastructures have to be modified from that of Figure 1 to that
shown in Figure 2.
Similarly, the principal difference between the ODC and the OS would be the relative proportion of ITE and NTE as is
shown in Figure 3. Furthermore a customers data centre (CDC) would also contain NTE - although generally providing
a connection to the access networks. For this reason, the present document considers its Global KPIs for operators data
centres to also be applicable to OSs and CDCs.
ETSI
---------------------- Page: 10 ----------------------
11 ETSI ES 205 200-2-1 V1.1.1 (2013-05)
The Global KPIs are therefore applicable to ODCs, OS and CDCs of all types, regardless of:
• their Availability Class as defined in EN 50600-1 [i.1];
• the business model of the data centre (such as operator, enterprise, co-location service or co-host service);
• the type, quantity and relative proportions of ITE and NTE.

Introduction
Energy costs continue to rise, a trend that will continue in the future, while broadband penetration is introducing new
active equipment to the network architecture. In this context, and to reflect other environmental aspects of
sustainability, it is vital that the main telecommunication actors implement effective general engineering of fixed and
mobile broadband networks and sites provisioning, managing or using those networks (i.e. operator sites, operator data
centres and customer data centres) in order to respond to critical issues of energy consumption while proposing essential
solutions to true broadband deployment.
These issues are of particular importance in data centres - both of operators and customers. To guide this process, it is
essential that metrics are defined, termed Global Key Performance Indicators (KPI ) that enable energy usage to be
EM
managed more efficiently.
The ES 205 200 series of standards comprises:
• ES 205 200-1: a generic requirements document addressing Global KPIs for operational infrastructures.
NOTE: Global KPIs do not address design/operation of components or subsystems of broadband deployment
networks.
• A sub-series ES 205 200-2 that defines the Global KPIs, and drives energy management targets, for specific
operational networks and sites and which describes how the Global KPIs are to be applied (which may be used
to support future regulatory objectives):
- ES 205 200-2-1: Data centres;
- ES 205 200-2-3: Mobile access networks.
These documents do not define KPI limits or targets (which is outside the scope of the ES 205 200 series of
standards).
These documents will accelerate:
• availability of operational infrastructure architectures and network implementations that use energy more
efficiently;
• the definition and attainment of sustainability objectives for operational broadband networks.
Within the present document:
• clause 4 explains the definition of a data centre in terms of the systems it comprises and the boundaries that
apply and shows that the present document is equally applicable to operator data centres, operator sites and
customers data centres;
• clause 5 describes how the Objective KPIs of the present document meet the requirements of
ES 205 200-1 [2];
• clause 6 describes the specific requirements of the Global KPI and the supporting Objective KPIs for data
centres;
• annex A discusses the roles of different types of Key Performance Indicators i.e. Technical, Objective and
Global in relation to the overall energy management concepts of the present document.

Figure 1: Schematic of core network together with fixed and mobile access infrastructures
With reference to Figure 1:
• an operator data centre (ODC) accommodates a mixture of information technology equipment (ITE) and
network telecommunication equipment (NTE);
• an operator site (OS) will also accommodate a mixture of ITE and NTE - where the NTE may provide
connections to connections to core, fixed access, terrestrial mobile access and satellite mobile access network
infrastructures.
It is unlikely that either the ODC or OS of Figure 1 would allow separate assessment of energy consumption of the ITE
and the various NTE for the disparate network infrastructures. As a result, the boundaries applied to ODC and OS in
relation to the objective of Global KPIs for operational infrastructures have to be modified from that of Figure 1 to that
shown in Figure 2.
Similarly, the principal difference between the ODC and the OS would be the relative proportion of ITE and NTE as is
shown in Figure 3. Furthermore a customers data centre (CDC) would also contain NTE - although generally providing
a connection to the access networks. For this reason, the present document considers its Global KPIs for operators data
centres to also be applicable to OSs and CDCs.
