Eliminating Data Center Hot
Spots: An Approach for
Identifying and Correcting Lost Air
Data center cooling is a hot
topic. But, when you consider the challenges associated
with cooling the latest generation servers, the growing
cost of infrastructure equipment, and the risks
associated with hotspots brought on by high-density
clusters and premature hardware failure, it’s easy to
understand the focus.
The traditional school of
thought suggests that additional cooling capacity is
needed to resolve
data center hot spots or be able to support future
IT loads, because overheating must mean that you need
more cooling. But recent studies have identified that
high-heat densities and/or inadequate cooling capacity
are not the inherent cause of hotspots. The real
issue is inadequate cooled air distribution.
How do you determine the effectiveness of your current
air distribution? Consider the following:
- Is your rated cooling
capacity greater than your critical load yet you
still have hotspots?
- Have more perforated tiles
been installed and cooling problems remain?
- How confident are you that
your current infrastructure can support future IT
equipment installations?
The new paradigm looks to regain
existing installed capacity by optimizing your data
center’s existing infrastructure, thereby improving
efficiency, reducing operating costs and eliminating
hotspots. Patrick Cameron, Director of Business
Development for DirectNET and Lars Strong P.E. for
Upsite Technologies share results of a study by The
Uptime Institute that details how reducing lost air
(also known as bypass airflow) will help eliminate
hotspots in your computer room.
Topics Covered:
- A Tutorial on Bypass
Airflow: What has been Lost can be regained!
- Hotspots: A Tutorial of Zone
Hotspots and Vertical Hotspots
- The Delayed Impact: Examples
of Thermally caused instability
- Measuring the Bypass Airflow
in Your Data Center
- The ROI: Reduced Motor Hp,
Maintenance and Latent Cooling Penalty
- A Case Study: How one
company saved $60,000 in previously planned capital
expenditures by successfully mitigating bypass
airflow
