Standard data centre 120 kW, 12+2 racks, including
cooling and UPS, installed in a standard room,,
,,,,,,
Fully functional data centre comprising an ITC climate
zone for the server and network systems, and a
separate technical climate zone for the UPS equipment
and low-voltage switchgear.

The ITC climate zone comprises two rack suites (depth
1200 mm) with 6 server racks and a network rack each,
and is fully isolated from the climate zone for the
electrical equipment by way of self-closing sliding
doors in the cold and hot aisles.

Both climate zones are enclosed by a complete housing
of double-panelled, foamed wall and roof elements with
a total thickness of 30 mm.

The 600 mm wide hot aisle and the 1200 mm wide cold
aisle are partitioned within the standard room
and are to this end provided with a partitioning panel
which passes over the server/network racks.

The standard data centre incorporates a fully
functional raised-floor construction, with air intake
and outlet grilles in the form of dip-galvanised
gratings.

Air-circulating cooling units (CRAC systems) are
installed in the cavity space of the raised floor. The
CRAC systems do not occupy space within the rack (Zero
U-Space Cooling Systems)

A CRAC system is installed under each server rack.
Each CRAC system offers a nominal output of 12 kW; the
average heat load capacity per rack is thus 10 kW,
taking into account n+2 redundancy over the total
number of CRAC systems.

The intake temperature for cooling is 20°C, observing
temperature limit values according to ASHRAE 2008
(max. 27°C) within the cold aisle.

The UPS climate zone possesses a further CRAC system
to dissipate the UPS heat loss. Through direct
injection of the UPS cooling air, a temperature level
of max. 22°C is maintained within the climate zone, in
accordance with the Eurobat guidelines on the
environment for 10-year batteries.

The cooled intake air is blown into the cold aisle by
EC fans under the floor gratings. Flat filter fleeces
are fitted between the fan grilles and the floor
gratings to filter the circulating air.

The intake temperature and speed of the EC fans are
regulated by a controller in the standard data centre,
which communicates with the controller of an optional
chiller station via a system bus for purposes of
energy efficiency optimisation. The controller is not
accommodated in the IT racks and thus does not occupy
rack installation space.


The standard data centre is equipped ready for use
with a cold piping system comprising polypropylene
piping; the individual heat exchangers are connected
by way of high-pressure hoses.

Required chiller set provided by the customer:
The standard data centre must be equipped with a
straight ball valve to regulate the air intake
temperature to the target value, a flowmeter and two
temperature sensors to measure the coolant flow volume
and the feed and return temperatures, as well as to
calculate the heat output.

Required chiller set must be supplied:
The standard data centre must be supplied without ball
valve and sensors for the coolant.
The volume of the medium is regulated by the
variable-speed pump of the chiller station of the
standard data centre, and the sensors are fitted in
the chiller station.

The standard data centre is equipped with two modular
UPS systems with 20 kW modules. Each system provides
for n+1 redundancy, and thus each UPS system is
supplied with 4 modules
to cover the possible connected load of 2 x 60 kW for
the ITC hardware.

Each UPS system possesses 10 battery strings with 28
Ah batteries, which are assigned jointly to all UPS
modules and ensure autonomy for a period of 13
minutes.

The standard data centre incorporates two switchgear
systems with fused feeders for the allocated rack
suite. The switchgear spreads the feeders over two
panels to establish an A/B power supply. The UPS
system feeds supply path A.
Supply path B must be connected to the mains supply
via overvoltage protection.

From the two switchgear systems, the distribution
busbars of the individual racks are wired ready for
use and comprise Power Distribution Units with 24 C13
and 6 C19 sockets. Each rack is provided with two PDUs
to establish an A/B power supply.

The power supply is routed above the racks. The data
cables are routed to the IT racks separately from the
power supply cables. The installation of the data
cables is to be performed by the site
operator/customer.

Lighting and service socket are protected by way of an
RCCB. Emergency lighting is installed.

The standard data centre is equipped with an early
fire detection system. To this end, air is drawn from
the raised floor of the hot aisle via a perforated
plastic pipe. The alarm is given by a monitoring
system with Web access and SNMP interface.
The standard data centre is installed and commissioned
ready for use (with the exception of data cabling),
including installation of the operating power supply
and cooling system.
