Pioneering Study Outlines Findings and Methods to
Eliminate Data Center
Hot Spots by Reducing Bypass
Airflow
 In data centers across the country, consistent and
reliable data center operations is continually being
compromised by data center hot spots. As manufacturers
continue to introduce high-heat density equipment and
computer room capacity requirements grow, data center
hot spots will get worse.
This white paper, written by the
Uptime Institute, is based on years of conducting
computer room monitoring, testing, surveys, and case
study research, which was gathered to pinpoint the
causes behind data
center cooling and data center management issues.
The findings are counter to original beliefs that
insufficient computer room air conditioning units or
high heat densities were the underlying cause of
computer room cooling issues. After collecting more than
15,000 individual measurements in 19 computer rooms
ranging in size and capacity, the culprit was actually
an issue called “bypass airflow.”
This White Paper Presents:
-
What’s Happening in the
Computer Room – how uncontrolled cooling causes
excessive data center heat loads and how previous
tactics, such as increasing computer room air
conditioning units, only made problems worse
-
Why and How Issues Arise –
case studies show how bypass airflow occurs
-
Testing and What to Avoid –
the best ways to conduct remediation testing and
baseline case studies
-
Problem Solving – recovering
wasted bypass airflow
-
Getting Results – statistic
based improvements, which reduced bypass airflow and
computer room temperatures
-
Addition Benefits –
eliminating hot spots increased the performance of
data center operations while saving energy, reducing
operating expenses and capital investments related
to computer room air conditioning units
