10. suitable for the racks ensure that the air flow direction matches Equipment
data centre - Air the air flow design for that area. This is
flow direction commonly front to rear or front to top.
Best Practices: IT If the equipment uses a different air flow
direction to that defined for the area into which it
is installed (such as right to left when the rack is
intended to be front to back) it should only be
used with a correction mechanism such as
ducts, or special racks that divert the air flow to
the defined direction.
Uncorrected equipment with non standard air
flow will compromise the air flow management
of the data centre and therefore restrict
temperature set points. It is possible to mitigate
this issue by segregating such equipment as per
practice 5.1.10.

Note that this may require changes to the
provisioning if the IT equipment is upgraded

Other openings opportunities in each rack. This includes;
· floor openings at the base of the rack
· Gaps at the sides, top and bottom of the

management tiles to reduce bypass. Maintain unbroken rows of Centre
cabinets to prevent re-circulated air – where
necessary fill with empty fully blanked racks.
Managing unbroken rows is especially important in
hot and cold aisle environments. Any opening
between the aisles will degrade the separation of
hot and cold air.

Best Practices: Air Management
Obstructions airflow and create turbulence, increasing the
resistance and increasing the energy requirements
of air movement and may increase velocities,
causing negative pressure. The use of overhead
cabling trays can substantially reduce these
losses.
5.1.8 Design – Hot / As the power densities and air flow volumes of IT New IT 3
cold aisle equipment have increased it has become Equipment
necessary to ensure that equipment shares an air
flow direction, within the rack, in adjacent racks
and across aisles. New build
or retrofit
The hot / cold aisle concept aligns equipment air
flow to create aisles between racks that are fed
cold air from which all of the equipment draws
intake air in conjunction with hot aisles with no
cold air feed to which all equipment exhausts air.

segregation different environmental requirements and / or Equipment
equipment airflow direction in a separate area.
Where the equipment has different environmental
requirements it is preferable to provide separate New build
environmental controls. or retrofit
This objective of this practice is to address the
issue of the data centre cooling plant settings
being constrained by the equipment with the most
restrictive environmental range or poor air flow
control as this compromises the efficiency of the
entire data centre.
This practice applies to IT, mechanical and
electrical equipment installed in the data centre.
