2. Environmental Summary
• Recirculation of Hot/Cold Air : with the current rack layout, there is a significant amount of
exhaust air traveling over the top of the racks resulting in significant hot spots at the intake
level….
• Unbalanced Static pressure : Most common inefficiency in the data center environment. With
the current high velocity in the plenum, there is no ability to control and slow down airflow in
the plenum therefore causing low static pressure and weak volumes of CFM through vented
tiles……
• Lack of real time visibility/temperature monitoring: Currently in the data center, there is no
equipment monitoring taking place. Without temperature monitoring at the server level, it is
impossible to judge a hot spot or react to a temperature increase leading to a disaster
scenario…..
*Throughout this CFD report, all points of concern as shown above, will be addressed through our FlowLogix Airflow
Management System, and supported by the latest in CFD modeling technology.*

12. Environmental Monitoring
• Technology Connection will monitor the environment through wire free sensors strategically
placed in cold aisles to ensure a constant balance in temperature, and record real-time data.
These sensors are monitored through software provided by Technology Connection that will
be owned by client and loaded onto a workstation provided by client. When the trending
data begins to change, our experts focus on that data to determine what in the environment
is causing that change whether it is a new cut out, a change in perforated tile placement, an
adjustment to CRAC unit settings, etc…

13. ANNUAL CFD MAINTENANCE
Technology Connection includes annual maintenance in every FlowLogix installation. Our team
of professionals stay proactive in not only maintaining, but continually working with you to
maximize all efficiencies. We will run up to 2 additional CFD’s per month for the duration of the
maintenance contract to insure airflow and energy efficiency is optimized. These additional
analyses may be used for, but not limited to any of the following purposes:
• Addition/removal of equipment in the
data center
• Energy/Airflow efficiency planning
• Data center layout alterations/planning
• Disaster Recovery planning
• CRAC unit Cycling

14. QUARTERLY HEALTH CHECKS
Once a quarter, Technology Connection will send a cooling specialist onsite to complete CFD
gathering of information from your data center. This gathering will include: CFD readings from
perforated tiles or supply vents, floor layout of racks and equipment, and operating set points
of CRAC/CRAH units. After information has been gathered, cooling specialist will return to
Technology Connection with all gathered data and deliver to CFD engineer. The CFD engineer
will then run an analysis and report findings to client’s FlowLogix representative. FlowLogix
representative will schedule a conference call with client to discuss findings from the health
check, as well as provide any recommendations the client may need to rectify any issues found
in data center revolving around cooling efficiency. The health check may be scheduled through
client’s FlowLogix sales representative.
