The document discusses Ainsworth's computational fluid dynamics (CFD) services for data centers. CFD uses modeling and simulation to analyze airflow patterns and identify hot spots. It is imperative for data centers because computing densities have increased, changing cooling requirements. Ainsworth's 5-step CFD approach involves measuring airflow, identifying issues, constructing an "as-is" plan, evaluating data, and providing recommendations. CFD validates if a data center's design can still adequately cool current equipment loads.

7. WHAT IS CFD ? COMPUTATIONAL FLUID DYNAMICS
 measure air temperature and air flow at critical points throughout the data centre
 Identify hot spots and air flow restrictions
 Perform a CFD analysis in problematic areas. This is a rigorous mean of evaluating airflow
patterns and may include important variables such as air pressure, temperature and velocity.
7

8. WHAT IS CFD ? COMPUTATIONAL FLUID DYNAMICS
 Evaluate and assess the data
 Construct an “AS IS” floor plan identifying issues with air flow, obstruction and other areas of
concern
The customer receives:
An in-depth account of airflow characteristics
A comprehensive report, including floor plans,
Which identifies problems and provides recommendations
With corresponding estimates

9. WHY IS CFD IMPERATIVE FOR ALL DATA CENTRES
 DATA CENTRES WERE CONSTRUCTED TO MEET A BASE CONFIGURATION – A CFD STUDY
CONFIRMS IF THE BASE DESIGN IS STILL ADEQUATE FOR CURRENT USE.
 COMPUTING DENSITIES HAVE INCREASED DRAMATICALLY AND THE COOLING
REQUIREMENTS AND PROFILE OF YOUR DATA CENTRE HAS LIKELY CHANGED
DRAMATICALLY AS WELL.
 WHAT WAS VALID YESTERDAY IS NOT VALID TODAY.
 VALIDATES THAT THE DATA CENTRE IS READY FOR NEW INFRASTRUCTURES AND PLANNED
PROJECTS.
 ARE YOU SPENDING MORE THAN YOU SHOULD BE ON COOLING?
 CONFIRMS WHERE YOU ARE COOLING THE DATA CENTRE VS WHERE THE COOLING IS
REQUIRED.
 CONFIRMS IF THE DATA CENTRE COOLING ARCHITECTURE IS OVER/UNDER DESIGNED?

10. OUR 5-STEP APPROACH
10

11. Delivering efficient airflow to the entire face of the rack, and ultimately the equipment inside it.
 High velocity and low
THE PROBLEM pressure creates unbalanced
airflow through the subfloor.
 Cold airflow through
perforated tiles is often weak
and inconsistent.
 Negative pressure from high
velocity in the subfloor can
pull air down through
perforated tiles instead of
forcing it up to the rack.
 CRAC unit fails to deliver a
steady, efficient airflow with a
balanced temperature.
 Cooling of the rack is
inefficient. Low areas may be
cool while the higher areas
remain untouched by cold air.
 This is what your data center
looks like when all of these
inefficiencies are occurring.
11

12. The FlowLogix system is an innovative combination of CFD modeling, airflow
management, and professional services to manage airflow in your data
center and distribute it to the heat load.
FlowLogix decreases your overall kW draw, providing significant energy
savings. In all cases this is accomplished without the installation of any
additional CRAC units.

Analysis Before and After:  On-site data gathering
 CFM readings
 Cable cutout leakage
STEP ONE  Lowest/highest flowing tiles
 Velocity/static pressure readings
 Rack temperatures 3ft and 6ft
 Return air temperatures/patterns to AC units
 AC unit efficiency
 Heat load patterns
The CFD Analysis will show us how
efficiently your room is operating from an
airflow standpoint. Once the analysis is
complete, we then engineer our FlowLogix
solution to improve your data center
conditions.

15. STEP TWO
Results
 Every perforated tile within the data center will
produce a significantly higher volume of air
 Provide ability to cool all required areas of the data
center
 Helps eliminate hot spots
 Increased air stratification

16. Cold Air Management
STEP THREE The data center space is never the same. Every
environment is different requiring a professional custom
approach. Some of the techniques used in step 3 may
include the following:
 Perforated tile management
 Addition of high-perforated tiles where needed
 Sealing of all unmanaged openings and cable cut-outs
 Cold aisle containment
 Blanking Panels
 Between 100 – 600 CFM is leaked through a
cable cutout opening causing limited static
pressure and significant mixing of hot and
cold air.
 Short cycling and improper perforated tile
placement cause hot spots and inefficient
airflow distribution to the rack face.

Heat and Return
Air Management
A 30-ton down-flow CRAC unit
may have a capacity of 27 tons
when operated at 72°F, but only
23 tons when operated at
68°F, delivering 18% greater
capacity at the higher operating
temperature!  Through return air management, it has been proven
From a cost perspective, it might that a 30-ton CRAC unit will produce more capacity
be possible to eliminate one in when drawing back warmer air.
five air handlers with the proper
return air temperature.
Results have proved:
By using innovative approaches in eliminating the warm air from re-
circulating into the cold aisle, FlowLogix has delivered a 3-11 degree drop
in temperature in the cold aisle on average.

Before FlowLogix After FlowLogix
1) Sensors provide real-time temperatures every 20 seconds
2) Set thresholds to stay within ASHRAE standards for critical servers.
3) Through FlowLogix quarterly health check program, stay in control with
real-time equipment temperatures and maximize energy savings.
18

19. AFTER FLOWLOGIX  Air velocity is lower while static pressure
is increased, creating an even supply of
cold air throughout the subfloor.
 Cold air is distributed evenly and higher
up the face of the rack.
 CRAC units deliver a steady, efficient
airflow with a balanced temperature.
 More of the rack is cooled.
 Now that the room is balanced with cold
air, the CRAC unit set points can be raised
to reduce energy costs. In some cases
they can even be shut off.
 This is what your data center looks like
after FlowLogix has been implemented.

22. FLOWLOGIX QUARTERLY HEALTH CHECKS
Ainsworth Inc. recognizes that data center and facilities
managers are short-staffed and their time is in high demand
daily. We have introduced Quarterly Health Checks to add
peace of mind, and essentially allow our clients to “outsource”
their airflow and energy efficiency requirements and updates
to Ainsworth’s professionals.
The following outlines this new service:
 Each quarter Ainsworth Inc. schedules onsite assessments
