Foreword
This final draft ETSI Standard (ES) has been produced by ETSI Technical Committee Access, Terminals, Transmission
and Multiplexing (ATTM), and is now submitted for the ETSI standards Membership Approval Procedure.
The present document is part 2, sub-part 1 of a multi-part deliverable covering operational energy management and
sustainability of broadband deployment, as identified below:
Part 1: "General requirements ";
Part 2: "Specific requirements":
Sub-part 1: Data centres;
Sub-part 2: Fixed (excluding cable) access networks;
Sub-part 3: Mobile access networks;
Sub-part 4: Cable Access Networks;
Part 3: "Monitoring of sustainability".
NOTE 1: Additional documents are in development by ETSI Technical Committee Access, Terminals,
Transmission and Multiplexing (ATTM) which include:
- 205 200-1-1: Energy management: Global KPIs: Operational infrastructures: Guidance (see NWIP
DES/ATTM-02025)

NOTE 2: A further document is under consideration ETSI Technical Committee CABLE to address "cable access
networks".
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.
ETSI

---------------------- Page: 5 ----------------------
6 Final draft ETSI ES 205 200-2-1 V1.2.0 (2014-01)
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.
This multi-part deliverable comprises:
• ES 205 200-1 [2]: 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 [i.10] 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 this multi-part deliverable).
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.
The comparative costs and environmental impacts of different energy sources are not addressed in the present
document.

1 Scope
The present document specifies Global Key Performance Indicators (KPI ) in relation to energy management for
EE
operator data centres (ODC), operator sites (OS) and customer data centres (CDC) and addresses the following
objectives:
• energy consumption;
• task efficiency;
• energy re-use;

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.
ETSI

---------------------- Page: 10 ----------------------
11 Final draft ETSI ES 205 200-2-1 V1.2.0 (2014-01)
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 customer 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.
The Global KPIs are therefore applicable to ODCs, OS and CDCs of all types, regardless of:
• their Availability Class as defined in CLC 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.
