Mechanical Technology — May 2015

Configuration details

The system consists of:

• Two scalable Symmetra PX160 and

PX96 modular UPSs per module of

16 to guarantee optimal efficiency.

• 18 NetShelter SX racks in the data

centre and a further 34 racks in the

service areas.

• Six new generation InRow Cooling

units with hot aisle containment and

an Air Flow Controller system and a

further 17 standard InRow Cooling

units in the service areas.

• StruxureWare for Data Centres DCIM

software solution, including Operation

and Energy Efficiency modules.

• Automatic LED lighting and automatic

door.

• Two Schneider Uniflair free-cooling

chillers.

• Schneider Electric cabinets and circuit

breakers.

• A Uniflair by Schneider Electric raised

floor.

New generation intelligent cooling

For the urbanisation of the IT room, Schneider

Electric proposed its InfraStruxure

solution:

an integrated, fully customisable and modular

offering that guarantees the highest availability

and operational efficiencies of the information

system. This solution includes modular power,

precision cooling, security, integrated monitor-

ing and management.

The IT room is cooled by a combination of

solutions comprising cooling production, distri-

bution and intelligent management.

Cooling production is provided by Uniflair

free-cooling chiller units, which are installed

on the roof of the building, and because of the

narrow French street in which the 22-story SAP

building is situated, these required a rather

spectacular method of delivery: the chillers had

to be winched into place from a Super Puma

helicopter.

Cooling distribution is provided by the InRow

precision air conditioning system installed

within the IT racks. These units capture heat

as close as possible to the emission source, i.e.

the servers. Connected to the EcoAisle solution,

which ensures hot aisle containment, this sys-

tem increases the cooling efficiency.

A genuine Schneider Electric innovation, the

Air Flow Controller connects the chillers installed

on the roof to the cooling units installed in the

data centre. The latter supplies cooling only when

necessary based on the parameters measured

in the containment – temperature, hygrometry

and air flow – thereby avoiding significant energy

loss. This system gives SAP France a target PUE

(power use effectiveness) level of 1.3.

This installation also includes 17 service

areas, each of which contains two racks and an

InRow cooling system, on all floors for horizontal

distribution on each different level.

The data centre is managed by StruxureWare

for Data Centres, the DCIM software suite from

Schneider Electric. This software generates au-

tomatic reports, giving the information systems

director an overview of the energy consumption

and signalling any problems in real time.

The project’s success and adherence to

a strict schedule relied on two specific fac-

tors inherent to SAP and Schneider Electric.

At Schneider Electric, cooperation between

the different SAP departments is welcomed:

“Throughout the project, the strong involvement

of SAP IT management together with facilities

managers, enabled a state-of-the-art data centre

– in terms of energy efficiency and availability

– to be built in record time,” explains Franck

Laporte, data centre sales account manager at

Schneider Electric France.

Joseph Cinquanta, IT account

manager at SAP France, emphasises

Schneider Electric’s ability to handle a

project in its entirety: “In my 15-year

career, this is the first time I’ve seen a

solution operational from day 1! The

all-in-one approach offers definite

advantages,” he affirms.
