Standard data centre 90 kW, 8+1 racks, including
cooling, for installation in a standard room,,
,,,,,,

Fully functional standard data centre comprising a
rack suite (depth 1200 mm) with 8 server racks and a
network rack, installed in a fully enclosed housing.

The standard data centre is 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 is partitioned within the
room and provided with a sliding door.
The cold aisle is 950 mm wide and connects to the
access area on the air side.

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 11 kW; the
average heat load capacity per rack is thus 9.5 kW,
taking into account n+1 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 cooled intake air is blown into the cold aisle by
EC fans under the floor gratings.

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 a 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 incorporates switchgear with
fused feeders for the rack suite. The switchgear
spreads the feeders over two panels to establish an
A/B power supply.

From the switchgear, 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.
