Use our free air performance tool to better understand your data hall. The tool uses air performance metrics and temperature data to quantify available cooling airflow and the impact of bypass and recirculation
How the tool works and what is required
• Input average temperatures from cooling unit and IT equipment supply and return points to find out your performance. For more accurate results weighted average temperatures should be used.
• The tool quantifies the average performance, rather than highlighting any extreme temperatures.
• A representative sample of IT temperatures should be recorded at the inlet and outlet, i.e. not in the cold or hot aisles for servers, but at the intake and exhaust points.
• Measurements should be recorded for every cooling unit which is moving air.
•The tool should be used for distinct air volumes, i.e. for a whole data hall with continuous raised floor area, rather than parts of it. Further information on the metrics is available here.

Glossary
Bypass – Cooled air that returns to CRAH units without cooling any IT equipment.
Recirculation – Air that is drawn from the IT equipment exhaust back to the server inlet without returning first to the CRAH for cooling, resulting in elevated server-inlet temperatures.
