8 Data centre spaces and access routes

Accommodation

The size and complexity of a data centre determine the variety and quantity of its spaces It is essential to consider modular construction techniques that facilitate future expansion.

The provision of on-site monitoring and/or management functionality shall be considered for all data centres

Consideration shall be given to locating toilet facilities in such a way as to minimise the requirements that the personnel has to cross the boundaries of Protection Classes

The accommodation of data centre spaces should consider the impact of: a) new technologies (flexibility); b) adaptation to changing parameters (adaptability); c) increasing demands for space (scalability)

The spatial relationship between the different data centre spaces should facilitate the overall operation based on adjacency factors

The floor plan should minimize the amount of demolition during any expansion phase

The design of a data center must align with its operational and security needs, featuring a well-organized layout that includes dedicated areas for utility and data services This entails having separate and redundant entrance rooms for telecommunications, fuel lines, water, and sewage Additionally, the building should accommodate essential spaces for electrical and mechanical systems to ensure efficient technical operations.

The control room space typically houses computer system and network traffic monitors, and increasingly building automation systems and security systems monitoring equipment

As needed, office(s) and meeting rooms should be provided adjacent to the control room space for supervisory functions and to form an emergency trouble-shooting area

The computer room space shall be designed to provide adequate space for initial and predicted quantities of

When designing a computer room, it is essential to align cabinets, racks, and frames in rows to create efficient aisles Key factors influencing the location of the computer room include its proximity to power sources, which minimizes the length of bus bars and cabling; closeness to mechanical distribution rooms to shorten the length of pipes and air ducts; and nearness to the communications distribution point, such as carrier entrance rooms, within the building.

Computer rooms should be limited to a maximum area of 600 m², with row lengths not exceeding 20 cabinets, racks, or frames The layout must adhere to the 'cold aisle / hot aisle' methodology, where the fronts of cabinets face each other in a cold aisle, and the rears face each other in a hot aisle To enhance energy efficiency, it is crucial to prevent the mixing of cool input air with hot exhaust air and to ensure a direct path for hot return air to the air conditioning units, as outlined in EN 50600-2-3.

Office areas should be at or near the main building entrance on the building perimeter to allow outside visibility.

Protection

When data center spaces and their connecting pathways are situated below the anticipated groundwater level or are at risk of flooding, it is essential to address potential water infiltration issues Key considerations include the elevation relative to surrounding drainage systems, the implementation of secure and continuous vapor barriers, and the installation of effective water and vapor extraction systems.

Floors

In the design phase, it is essential to establish the floor loading requirements, which encompass the weight of access floors in data center areas and the access routes leading to them.

Table 1 provides guidance on such loads

Load capacity guidance Data centre spaces and access routes to those spaces

Other spaces Electrical and mechanical spaces Computer room

Floor loads Uniform load (min) 5 kN/m 2 12 kN/m 2 20 kN/m 2 -

Point load (min) 2,0 kN 5,0 kN 7,5 kN 1,5 kN

Ceiling loads Hanging load (min) 1,5 kN/m 2 2,5 kN/m 2 3,0 kN/m 2 -

The floors and flooring materials shall be capable of supporting the required static and dynamic loads Flooring materials shall to be resistant to the expected levels of abrasion

Future expansion should be considered when determining the finished floor elevation

Incorporating an access floor in the design phase of a data centre is crucial, as it significantly impacts infrastructure delivery and any decisions made are often irreversible.

To effectively manage the pathways for data center infrastructures, including power, environmental control, and telecommunications cabling, an access floor should be utilized beneath the equipment it supports, as outlined in this sub-clause.

Access floors are made up of interchangeable square or rectangular panels designed to meet specific load requirements in accordance with EN 12825 These panels are supported by adjustable pedestal assemblies that securely engage and position the panels while allowing for horizontal stringers The pedestals are anchored to the floor using glue and/or bolts.

PVC is not an ideal choice for flooring material It is essential to bolt stringers securely The access floor must maintain a minimum clear height of 500 mm above the slab If the environmental control concept or infrastructure distribution during the data centre's lifespan prevents a 500 mm access floor installation, higher access floor heights should be considered.

Ceilings

During the design phase an assessment of the ceiling loading requirements in data centre spaces shall be made

Table 1 provides guidance on such loads

Where suspended ceilings are installed in data centre spaces, a ceiling system constructed from non- particulating materials shall be installed

The minimum clear height for computer rooms, measured from the finished floor to the ceiling or ceiling beams, should be at least 3.0 meters This requirement is influenced by the environmental control concept and various infrastructure elements, such as raised flooring and overhead cabling.

In rooms with freely circulated air, the ceiling should be smooth and free of beams If beams are necessary, they must be aligned parallel to the airflow to avoid obstructing air circulation When beams are positioned perpendicular to the airflow, installing a suspended ceiling is advisable.

When designing spaces such as control centers, offices, and lobbies that are frequently occupied, it is essential to incorporate suspended ceiling systems for improved acoustics However, in technical rooms, including computer and telecommunication areas, suspended ceilings are generally not advisable unless necessary for specific functions, such as facilitating air return.

Access to data centre spaces

In data centre spaces and in access routes to those spaces along which equipment and goods will be transported, stairs shall be avoided in favour of ramps or lifts

The width of ramps and lift doors shall be in accordance with those of doors in interior wall specified in 7.4.2

Vapour density

Effective humidity control is essential in data centres to ensure optimal conditions for IT and telecommunications equipment Inadequate humidity management can lead to equipment malfunctions and reduced performance Additionally, the absence of vapor barriers can result in harmful ice or condensation forming behind exterior walls and under roofs during colder temperatures.

A comprehensive risk assessment for vapour seal requirements will be performed, followed by the implementation of necessary measures The vapour seal is essential for regulating humidity levels and preventing vapour infiltration into controlled environments.

To prevent future humidity issues, it is essential to install vapour barriers during new construction, as they are challenging to install and seal in existing buildings Flexibility is crucial to accommodate ongoing expansion, making it necessary to analyze and identify areas that currently need vapour barriers or may require them in the future.

9 Fire compartments, fire barriers and fire suppression systems

General

Data centre spaces, along with their access routes and infrastructure pathways, must be designed as defined fire compartments These compartments should be bounded in three dimensions and equipped with appropriate fire performance levels to effectively prevent the spread of fire and its byproducts, thereby minimizing potential losses.

When selecting compartment boundaries, it is essential to consider the fire impact within each compartment Fire compartments must be defined by the boundaries of Protection Classes outlined in EN 50600-2-5, which also specifies the fire performance requirements for these boundaries Notably, the density of fire compartments can exceed the areas defined by these boundaries.

To minimize fire hazards in a compartment, it is essential to implement containment, detection, and suppression systems, allowing for the disregard of materials' smoke and flame-spread characteristics Additionally, when the compartment houses electrical equipment, these systems must also address the corrosive gas emissions from materials, ensuring comprehensive safety measures are in place.

With each fire compartment, different approaches may be taken in relation to fire containment, detection and suppression Fire containment, detection and suppression are addressed in EN 50600-2-5

This sub-clause addresses the management of fire barriers together with the constructional aspects of fire compartments and associated spaces related to specific suppression systems

Fire barriers

Fire compartments are separated in three dimensions by fire barriers with a defined fire rating performance

All penetrations of fire barriers (e.g walls, floors or ceilings) shall be protected by appropriate fire-stopping techniques (see EN 50600-2-5) that reinstate the original fire rating of the barrier

NOTE Such techniques include fire-stopping materials and/or penetration sealing systems

Fire-stopping techniques must be installed following the manufacturer's or supplier's instructions Each fire stop should be clearly labeled or marked to indicate its function, ensuring easy identification during future construction activities.

Fire barriers and seals that support fire suppression systems should only be penetrated when absolutely necessary and must be resealed after work is completed to restore the original fire rating The reinstatement of fire ratings for these barriers must utilize the designated fire-stop materials and fire-stopping techniques.

When periods of infrastructure installation work are interrupted and unattended, the penetrations shall be at least temporarily sealed with appropriate materials (fire cushions, etc.)

Fire compartments for gaseous extinguishing systems

In the design and engineering of fire compartments within data center spaces, it is essential to consider air-tightness when implementing a total flooding suppression system.

Longer standing time is recommended to create longer safe period, as fire can ignite again, when the suppression gas disappears

In the design and engineering of data center fire compartments, it is essential to ensure air-tightness when utilizing a total flooding suppression system The fire compartment must meet the specified N-50 value for optimal effectiveness.

Fire suppression

When implementing a fire protection concept that incorporates a gaseous suppression system, it is essential to allocate space for the storage of fire suppression medium containers Additionally, the placement of these storage facilities should prioritize ease of maintenance.

Fire suppression medium storage containers should be installed in a dedicated room, ideally located near computer rooms, to ensure effective fire safety measures.

Even if no fire suppression system is considered initially an appropriate space should be allocated

Design phase

During the design phase consideration shall be given to the use of modular prefabricated construction elements which offer the possibility to add extra elements when more space is required

Multi-layered constructions such as room in room should be considered at the design phase.

Inter-relationship of functional spaces

During project initiation the requirements shall be defined by considering, as a minimum, the following: a) security level, b) capacity requirements, c) spatial layouts, d) project-specific technical and functional requirements

The entry to the computer room(s) should be positioned away from the direct access to the exterior

Support equipment in a data center includes secondary or tertiary power distribution systems, static switches, and fire suppression tanks While prioritizing the layout of IT systems, it is essential for data center designers to collaborate early with mechanical and electrical systems engineers Given that a data center's IT equipment inventory can change significantly within a 3 to 5 year period, the installation of IT equipment in cabinets, racks, or frames must be designed with flexibility in mind to accommodate future changes.

For spacing between the rows of racks see EN 50600-2-4

The computer room spaces are essential to data centres, offering a suitable physical and functional environment for sensitive IT and telecommunications equipment Key considerations include floor size, shape, height, load capacity, and interior fit-out features such as single person interlocks, raised access floors, racks, and cabinets.

To ensure future growth of the computer room, it is advisable to include expansion options next to the computer room within the Protection Class 4 area Given the various factors influencing the IT environment, accurately predicting expansion requirements can be challenging Therefore, it is beneficial to assess the facility's expected lifespan, analyze historical trends, and plan for at least a 20% increase beyond the projected growth.

Consideration shall be given to the accommodation of incoming fibre and/or copper cables See EN 50600-2-4

When planning telecommunications spaces, it is essential to account for the incoming fiber and copper backbone, along with the necessary electronics, telecom switches, and components Additionally, proper consideration should be given to fiber and copper patch and termination panels for effective distribution to patch panels and racks within the computer room.

Utilities

Underground utility services are always preferred Overhead services can only be accepted if there is more than one feed and for data centres of a lower availability class

To ensure safety and efficiency, a minimum separation of 20 meters should be maintained along the entire route for redundant services Additionally, different utility feeds must be spaced at least 1.2 meters apart If these distance requirements cannot be met, it is essential to implement special physical protection measures.

Personnel entrance and lobby

As an intermediate room between IT rooms and public areas an entrance lobby shall be provided.

Docking bay

A data centre shall have an area where deliveries can be brought into the data centre and equipment or waste can be taken out of the data centre

Receiving rooms should be strategically placed on the building perimeter for convenience, with enclosures or shading to protect deliveries from adverse weather A well-designed loading dock is essential for accommodating delivery trucks and facilitating the distribution of electronic, electrical, and mechanical equipment The receiving area must be versatile enough to handle trucks of all sizes, with small facilities utilizing exterior areas like scissors lifts, while larger facilities can incorporate interior spaces with dock levelers Additionally, the design should include provisions for waste recycling.

Storage rooms should be strategically placed near receiving and equipment rooms to ensure efficiency It is essential to allocate adequate space for anticipated items, including paper, cabling, and hardware Additionally, these storage areas can be designed to adapt for future needs, such as housing electronic equipment and DC batteries.

Physical protection against external hazards

Physical protection against external threats is crucial for data center buildings and computer rooms Fire risks, along with heat radiation and smoke or toxic fumes produced during a fire, directly impact the operational safety and availability of these facilities.

In addition to the fire risk, IT equipment necessitates robust protection against water ingress from leaks, floods, and firefighting efforts, as well as intrusion threats The key challenge lies in balancing the necessary protection levels with the flexibility and modularity essential for adapting to the fast-evolving and expanding IT landscape.

Standard building codes for fire safety aim to protect occupants and minimize damage to neighboring properties A fire test is deemed successful if the cold face of the specimen remains below 180 °C throughout the test duration However, this temperature threshold does not satisfy the requirements for IT equipment, which has not been adequately addressed in these codes Consequently, the protection levels outlined in building codes are inadequate for areas housing IT equipment and data storage Additionally, these codes fail to account for protection against smoke and water from firefighting efforts.

B.3 Protection for IT equipment and data storage

To ensure adequate fire protection, it is essential to consider various types of safeguards First, protection against flaming and flashover, known as Integrity, must comply with standard building codes, requiring suppliers to provide fire test reports that demonstrate the fire rating is achieved A test is deemed successful if the cold face temperature of the specimen remains below 180 °C Second, addressing heat radiation from a fire is crucial; therefore, when selecting construction materials, it is important to base choices on the temperature levels recorded during fire tests, which can be found in the corresponding fire test reports.

Calculation of the thermal performance of a material (also known as thermal resistance)

The thermal resistance \( R \) of a material quantifies its capacity to impede heat transfer at a specified thickness, serving as a key indicator of insulation effectiveness This value is derived using Formula B.1.

R = t/λ (B.1) where t is the material thickness λ is the thermal conductivity (W/(m.K)

Thermal conductivity (\(\lambda\)) quantifies a material's capacity to conduct heat, expressed in watts per meter per Kelvin (W/(m·K)) Typically, denser materials exhibit higher thermal conductivity, making them less effective as insulators, while lightweight materials possess lower conductivity, enhancing their insulation properties Consequently, a lower Lambda value indicates superior insulation performance.

Fires can reach temperatures of up to 1,000 °C for varying durations, typically tested for 30, 60, 90, or 120 minutes, corresponding to fire ratings F30, F60, F90, and F120 A crucial factor in these tests is the heat load, which refers to the amount of fuel available to sustain the fire.

General

Physical protection against external threats is crucial for data center buildings and computer rooms Fire risks, along with heat radiation and smoke or toxic fumes produced during a fire, directly impact the operational safety and availability of these facilities.

IT equipment must be safeguarded against water ingress, including leakage, floods, and firefighting water, in addition to fire risks The key challenge lies in achieving the necessary protection while maintaining the flexibility and modularity essential for adapting to the fast-evolving and expanding IT landscape.

Building codes

Standard building codes for fire safety aim to protect occupants and minimize damage to neighboring properties A fire test is deemed successful if the cold face of the specimen remains below 180 °C throughout the test duration However, this temperature threshold does not satisfy the requirements for IT equipment, which has not been adequately addressed in these codes Consequently, the protection levels outlined in building codes are inadequate for areas housing IT equipment and data storage Additionally, these codes fail to account for protection against smoke and water from firefighting efforts.

Protection for IT equipment and data storage

To ensure adequate fire protection, it is essential to consider various types of safeguards First, protection against flaming and flashover, known as Integrity, must comply with standard building codes, requiring suppliers to provide fire test reports that confirm the fire rating is met A successful test is indicated when the cold face temperature of the specimen remains below 180 °C Second, addressing heat radiation from a fire is crucial; therefore, when selecting construction materials, it is important to base choices on the temperature levels documented in the fire test report.

Calculation of the thermal performance of a material (also known as thermal resistance)

The thermal resistance \( R \) of a material quantifies its capacity to impede heat transfer at a specified thickness, serving as a key indicator of insulation effectiveness This resistance is determined using Formula B.1.

R = t/λ (B.1) where t is the material thickness λ is the thermal conductivity (W/(m.K)

Thermal conductivity (λ) quantifies a material's capacity to conduct heat, expressed in watts per meter per Kelvin (W/(m·K)) Typically, denser materials exhibit higher thermal conductivity, making them less effective as insulators, while lightweight materials possess lower conductivity, enhancing their insulation properties Consequently, a lower Lambda value indicates superior insulation performance.

Fires can reach temperatures of up to 1,000 °C for varying durations, typically tested at intervals of 30, 60, 90, or 120 minutes, corresponding to fire ratings F30, F60, F90, and F120 A critical factor in these tests is the heat load, which refers to the amount of fuel available to sustain the fire.
