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 of data
centres has become critical both from an environmental point of view (reduction of carbon footprint) and with
respect to economic 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 and physical security. Effective management
and operational information is required to monitor achievement of the defined needs and objectives.
This series of European Standards 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, facility managers, ICT managers, project managers, main contractors;
2) architects, consultants, building designers and builders, system and installation designers;
3) facility and infrastructure integrators, suppliers of equipment;
4) installers, maintainers.
At the time of publication of this European Standard, the EN 50600 series currently comprises the following
standards:
— EN 50600-1, Information technology — Data centre facilities and infrastructures — Part 1: General
concepts;
— EN 50600-2-1, Information technology — Data centre facilities and infrastructures — Part 2-1: Building

The inter-relationship of the standards within the EN 50600 series is shown in Figure 1.
Figure 1 — Schematic relationship between the EN 50600 standards
EN 50600-2-X standards 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.
This European Standard 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, 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. shall be carried out in cooperation with

the IT and telecommunications personnel, network professionals, the facilities manager, the IT end users,
and any other personnel involved.
This European Standard is intended for use by and collaboration between facility managers, ICT managers,
and main contractors.
This series of European Standards does not address the selection of information technology and network
telecommunications equipment, software and associated configuration issues.

c) a monitored PUE KPI;
d) an asset management policy;
e) an environmental control policy;
f) a lifecycle management policy;
g) an energy management policy.
5 Operational information and parameters
5.1 General
In general, operators should understand the designed capacity and optimum operating parameters of the
data centre. This is extremely important to maintain efficient operations and reliable service.
It is particularly important for the operators to understand the “N” design capacity to ensure that this is not
exceeded. If the “N” design capacity is exceeded then some of the design redundancy will be lost which may
effectively reduce the reliability class of the data centre.
At handover to operations instructions shall be delivered by designers and constructors on how to handle
operational parameters of the infrastructure at different loads.
———————
1) It is recognized that the term “efficiency” should be employed for PUE but “effectiveness” provides continuity with earlier market
recognition of the term.

---------------------- Page: 13 ----------------------
SIST EN 50600-3-1:2016
EN 50600-3-1:2016
At the beginning of data centre lifecycle IT loads will be low; therefore instructions for efficient part load
operation are very important.
The following subclauses describe the information that operation retrieves from the various data centre
subsystems of EN 50600-2-1 to EN 50600-2-5 together with operational parameters that shall be configured
during the lifecycle of the data centre to achieve the goal to run at the optimal point for the given IT load.
5.2 Building construction as per EN 50600-2-1
All information delivered by the building management systems relating to any of the other subsystems in the
building will be described in the relevant Subclauses 5.3 to 5.6.
The following information shall be handed over to operations:
a) maximum bearable load by construction;
b) escape routes;
c) technical: transmission heat/cooling;
d) documentation about installation for flood control;
e) regulatory requirements;
f) acoustic protection;
g) use of water-polluting substances (effluent water);
h) environmental regulations.
5.3 Power distribution as per EN 50600-2-2
5.3.1 General
To operate a data centre in a safe and efficient mode the following information is required at all metering
points defined by the level of granularity:
a) active power load;
b) apparent power load;
c) power factor;
d) voltage;
e) current on each phase;
f) energy usage (consumption in kWh).
The following information shall be handed over to operations:
1) main power capacity;
2) back-up power source (e.g. generator);
3) power distribution capacities;
12
---------------------- Page: 14 ----------------------
SIST EN 50600-3-1:2016
EN 50600-3-1:2016
4) UPS capacity, battery capacity, modularity and efficiency at various IT loads;
5) resilience plan;
6) plan for protection from electrostatic discharge;
7) granularity level of energy efficiency enablement.
5.3.2 Generator parameters
The generator takes over after failure of the mains power supply. When the mains power supply returns a
smooth power transition from the generator should be made. The procedure provides two parameters that
need to be defined:
a) T1 – the time between the failure of the main supply and the start of the generator;
b) T2 – the time the generator shall run before switch off.
T1 should be large enough to prevent the generator from starting when it is not really needed. The UPS will
keep the IT up and running for at least some minutes, but a safety period is needed in case the generator will
fail to start and IT needs to be shut down. Also environmental conditions shall be kept under control to
prevent overheating.
T2 should be large enough to ensure that the loading of the UPS batteries is on a level that enables a
second failure of the mains power supply to be tolerated. In the worst case the second failure of mains power
supply will happen immediately after the generator has switched off.
The ideal values of T1 and T2 will vary dependent on the capacity of the data centre and its current load. T1
and T2 shall be determined from the following:
1) IT load;
2) UPS capacity;
3) UPS battery re-charge/discharge times;
4) Expected rise of temperature after failure of the cooling;
5) Generator type and capacity.
Optimization of T1 an d T2 aims to protect the generator from bad working conditions, i.e. starting too early
when not needed, not running long enough to securely handle consecutive failings of the mains power
supply or running too long thus increasing fuel costs.
5.4 Environmental control as per EN 50600-2-3
5.4.1 General
For environmental control the basic measured parameters are temperature and humidity which need to be
reported based on the level of granularity available. Some of the spaces can have additional environmental
requirements such as control of the level of contaminants.
The following information shall be handed over to operations:
a) the cooling efficiency at various load conditions;
13
---------------------- Page: 15 ----------------------
SIST EN 50600-3-1:2016
EN 50600-3-1:2016
b) a document in which moisture control is detailed under various external environmental conditions (i.e.
dry cold winters and hot humid summers);
c) example scenarios detailing the observable parameters which determine overall cooling efficiency and
the interplay between those parameters, e.g. ventilator speeds, chilled water temperature, free cooling
capabilities, IT heat load and IT airflow requirements. Metering should be in place to facilitate this
process;
d) cooling capacity of each cooling component;
e) maximum cooling capacity of the computer room space;
f) maximum cooling capacity per cabinet.
5.4.2 Air handling parameters
With increasing IT load, computer rooms with access floor cooling require management of tiles with
openings, pressure and cold water temperature at CRACs.
At low part load, openings are required at racks loaded with IT only. Low pressure will be sufficient to provide
the necessary air flow and the cold water temperature can be higher as there is only little cooling capacity
needed.
Operations shall be provided with an instruction set on how to adjust the cooling systems to match the heat
load.
Where access floors are used for cooling this may include changing the open space in ven

63 Introduction
64 The unrestricted access to internet-based information demanded by the information society has led to an
65 exponential growth of both internet traffic and the volume of stored/retrieved data. Data centres are housing
66 and supporting the information technology and network telecommunications equipment for data processing,
67 data storage and data transport. They are required both by network operators (delivering those services to
68 customer premises) and by enterprises within those customer premises.
69 Data centers need to provide modular, scalable and flexible facilities and infrastructures to easily
70 accommodate the rapidly changing requirements of the market. In addition, energy consumption of data
71 centres has become critical both from an environmental point of view (reduction of carbon footprint) and with
72 respect to economic considerations (cost of energy) for the data centre operator.
73 The implementation of data centres varies in terms of:
74 a) purpose (enterprise, co-location, co-hosting, or network operator facilities);
75 b) security level;
76 c) physical size;
77 d) accommodation (mobile, temporary and permanent constructions).
78 The needs of data centres also vary in terms of availability of service, the provision of security and the
79 objectives for energy efficiency. These needs and objectives influence the design of data centres in terms of
80 building construction, power distribution, environmental control and physical security. Effective management
81 and operational information is required to monitor achievement of the defined needs and objectives.
82 This series of European Standards specifies requirements and recommendations to support the various
83 parties involved in the design, planning, procurement, integration, installation, operation and maintenance of
84 facilities and infrastructures within data centres. These parties include:
85 1) owners, facility managers, ICT managers, project managers, main contractors;
86 2) architects, consultants, building designers and builders, system and installation designers;
87 3) facility and infrastructure integrators, suppliers of equipment;
88 4) installers, maintainers.
89 At the time of publication of this European Standard, EN 50600 series will comprise the following standards:
90 EN 50600-1: Information technology – Data centre facilities and infrastructures – Part 1: General concepts;
91 EN 50600-2-1: Information technology – Data centre facilities and infrastructures – Part 2-1: Building
92 construction;
93 EN 50600-2-2: Information technology – Data centre facilities and infrastructures – Part 2-2: Power
94 distribution;
95 EN 50600-2-3: Information technology – Data centre facilities and infrastructures – Part 2-3: Environmental
96 control;
97 EN 50600-2-4: Information technology – Data centre facilities and infrastructures – Part 2-4:
98 Telecommunications cabling infrastructure;
99 EN 50600-2-5: Information technology – Data centre facilities and infrastructures – Part 2-5: Security

106 EN 50600-2-X standards specify requirements and recommendations for particular facilities and
107 infrastructures to support the relevant classification for “availability”, “physical security” and “energy efficiency
108 enablement” selected from EN 50600-1.
109 This European Standard addresses the operational and management information (in accordance with the
110 requirements of EN 50600-1). A data centre’s primary function typically is to house large quantities of
111 computer and telecommunications hardware which affects the construction, operation, and physical security.
112 Most of the data centres may impose special security requirements. Therefore, the planning of a data centre
113 by the designer and the various engineering disciplines that will assist in the planning and implementation of
114 the design of the data centre i.e. electrical, mechanical, security, etc. shall be carried out in cooperation with
115 the IT and telecommunications personnel, network professionals, the facilities manager, the IT end users,
116 and any other personnel involved.
117 This European Standard is intended for use by and collaboration between architects, building designers and
118 builders, system and installation designers.
119 This series of European Standards does not address the selection of information technology and network
120 telecommunications equipment, software and associated configuration issues.

231 4 Operational information and parameters
232 4.1 General
233 In general, operators should understand the data centre facility infrastructure and run it at the optimum point.
234 This is extremely important, not only for efficient operations under various normal conditions, but also defines
235 the capability of the operator to handle various failure conditions.
236 At handover to operations instructions shall be delivered by planning and engineering on how to handle
237 operational parameters of the infrastructure at different loads. Especially at the beginning of data centre life
238 cycle IT loads will be low; therefore instructions for efficient part load operation are very important.
239 The following clauses describe the information that operation retrieves from the various data centre
240 subsystems of EN 50600-2-1 to EN 50600-2-5 together with operational parameters that shall be configured
241 during the lifecycle of the data centre to achieve the goal to run at the optimal point for the given IT load.
242 4.2 Building construction (EN 50600-2-1)
243 All information delivered by the building management systems relating to any of the other subsystems in the
244 building will be described in the related clause.
245 The following information shall be handed over to operations:
246 a) Maximum bearable load by construction;
247 b) Escape routes;
248 c) Technical: transmission heat/cooling;
249 d) Documentation about installation for flood control;
250 e) Regulatory requirements;
251 f) Acoustic protection;
252 g) Use of water-polluting substances (effluent water);
253 h) Environmental regulations.
254 4.3 Power distribution (EN 50600-2-2)
255 4.3.1 General
256 To operate a data centre in a safe and efficient mode the following information is required at all metering
257 points defined by the level of granularity:
258 a) active power load;
259 b) apparent power load;
260 c) power factor;
261 d) Voltage;
262 e) Current on each phase;
---------------------- Page: 12 ----------------------
oSIST prEN 50600-2-6:2014
– 11 – prEN 50600-2-6:2014
263 f) energy usage (consumption in kWh).
264 The following information shall be handed over to operations:
265 a) Main power capacity;
266 b) Back-up power source (e.g. generator);
267 c) Power distribution capacities;
268 d) UPS capacity, battery capacity, modularity and efficiency at various IT loads;
269 e) Concept of resilience;
270 f) Concept of protection from electrostatic discharge;
271 g) Energy efficiency level of granularity (complexity level).
272 4.3.2 Generator parameters
273 At failure of the main power supply the generator is started to take over. After return of the main the load is
274 smoothly put back and the generator is stopped. The procedure provides two parameters that need to be
275 defined:
276 a) T1 – the time between the failure of the main supply and the start of the generator;
277 b) T2 – the time the generator shall run before switch off.
278 T1 should be large enough to prevent the generator from starting when it is not really needed. UPS will keep
279 the IT up and running for at least some minutes, but a safety period is needed in case the generator will fail
280 to start and IT needs to be shut down. Also environmental conditions must be kept under control to prevent
281 overheating.
282 T2 should be large enough to ensure loading of the UPS batteries on a level that a second failure of the main
283 can be handled. Worst case the second failure of main will happen immediately after switch off of the
284 generator.
285 The ideal values of T1 and T2 will vary dependent on the capacity of the data centre and its current load. T1
286 and T2 shall be determined from the following:
287 a) IT load;
288 b) UPS capacity;
289 c) UPS battery re-charge/discharge times;
290 d) Expected rise of temperature after failure of the cooling;
291 e) Generator type and capacity.
292 Optimisation of T1 and T2 aims to protect the generator from bad working conditions, i.e. starting too early
293 when not needed, not running long enough to securely handle consecutive failings of the main or running too
294 long thus increasing fuel costs.

295 4.4 Environmental control (EN 50600-2-3)
296 4.4.1 General
297 For environmental control the basic measured parameters are temperature and humidity which need to be
298 reported and related based on the level of granularity. Some of the spaces may also have additional control
299 requirements such as level of contaminants.
300 The following information shall be handed over to operations:
301 a) The cooling efficiency at various load conditions;
302 b) A document in which moisture control is detailed under various external environmental conditions (i.e.
303 dry cold winters and hot humid summers);
304 c) Example scenarios detailing the observable parameters determining overall cooling efficiency and the
305 interplay between ventilator speeds, chilled water temperature, free cooling capabilities, IT heat load and
306 IT airflow requirements. Metering should be in place to facilitate this process;
307 d) Cooling capacity of each cooling component;
308 e) Maximum cooling capacity of the computer room space;
309 f) Maximum cooling capacity per cabinet.
310 4.4.2 Air handling parameters
311 With increasing IT load, computer rooms with access floor cooling require management of tiles with
312 openings, pressure and cold water temperature at CRACs.
313 At low part load, openings are required at racks loaded with IT only. Low pressure will be sufficient to provide
314 the necessary air flow and the cold water temperature can be higher as there is only little cooling capacity
315 needed.
316 Operations shall be provided with an instruction set on how to adjust the cooling systems to match the heat
317 load.
318 Where access floors are used for cooling this may include changing the open space in vented tiles, adding
319 vented tiles to new equipment locations and removing them where equipment is removed.
320 Where CRAC units with variable speed fans are implemented this may include adjusting the fan speed to
321 increase or reduce the volume of air provided for cooling.
322 Where chilled water cooling systems are implemented this may include varying the temperature of the cold
323 water supply to match the cooling requirement.
324 The instructions should indicate whether redundant equipment such as CRAC units should be in service
325 continuously or left in standby. The decision will normally depend on the relative efficiency of each operating
326 mode.
