Code for design of data centers
1 General provisions
1.0.1 To standardize the design of the data center, ensure that the electronic
information system operates safely, stably and reliably, make the technology
advanced, economically reasonable, safe and applicable, energy saving and
environmental protection, it hereby formulates this code.
1.0.2 This code applies to the design of newly built, rebuilt, expanded data
1.0.3 The design of the data center shall follow the principle of coordination
between the recent construction scale and the long-term development plan.
1.0.4 In addition to complying with this code, the design of the data center shall
also comply with the relevant national standards.
2 Terms and symbols
2.1 Terms
2.1.1 Data center
A building site that provides an operating environment for a centralized
electronic information equipment, which may be one or several buildings, or
may be part of a building, including a computer room, an auxiliary area, a
support area, an administrative area.
2.1.2 Computer room
A building space which is mainly used for the installation and operation of data
processing equipment, including the server room, network room, storage room
and other functional areas.
2.1.3 Auxiliary area
A place for installation, commissioning, maintenance, operation monitoring and
management of electronic information equipment and software, including wire-
incoming room, test equipment rooms, general control centers, fire and security
control rooms, unpacking areas, spare parts warehouses, printing rooms,
maintenance room and other areas.
2.1.4 Support area
Areas providing power support and safety for the computer room and auxiliary
area, including power transform and distribution room, diesel generator room,
battery room, air-conditioning room, power station room, uninterruptible power
supply system, fire-fighting facilities, etc.
2.1.5 Administrative area
A place which is used for daily administrative management and management
of equipment as entrusted by customers, including offices, foyers, duty rooms,
washrooms, locker rooms, user studios, etc.
2.1.6 Business recovery data center
A place wherein the critical business functions such as data processing and
support are continued in case of a disaster to substitute the operation of the
production system, including restricted areas, regular areas, dedicated areas.
2.1.7 Restricted area
2.1.16 Electromagnetic shielding
The use of conductive material to reduce the penetration of the alternating
electromagnetic field into the designated area.
2.1.17 Electromagnetic shielding enclosure
A building space which is specifically designed to attenuate and isolate the
internal or external electric and magnetic fields.
2.1.18 Cut-off waveguide vent
A device which integrates the cut-off waveguide with the vent, which allows air
to circulate and attenuate electromagnetic waves in a certain frequency range.
2.1.19 Modular electromagnetic shielding enclosure
An electromagnetic shielding enclosure which, according to the design
requirements, has modular structures and is assembled at construction site by
the pre-formed shielding enclosure modular plate, structural member, shielding
components, etc.
2.1.20 Welded electromagnetic shielding enclosure
An electromagnetic shielding enclosure whose main structure is a fixed
structure built by field welding.
2.1.21 Remote power panel (RPP)
An equipment which provides power distribution management equipment for
cabinets arranged in rows or by functional area.
2.1.22 Horizontal distribution area cabinet
A horizontal distribution area device that provides network services for cabinets
arranged in rows or by functional area.
2.1.23 Intelligent cabling management system
A complete software and hardware integration system which realizes intelligent
management of tracking, recording, reporting of the connection status of the
wiring system and network equipment through real-time monitoring of the port
connection properties of the electronic distribution equipment.
