Data Center Airflow Management and Monitoring
Effective data center airflow management helps ensure that conditioned air reaches critical IT equipment and heated air is properly returned to the cooling system. Air conditioning alone isn't enough—CRAC/CRAH systems also need adequate, unrestricted airflow to maintain proper cooling.
Restricted airflow can result from a clogged filter, failing blower motor, unbalanced fans or other ventilation problems. Without monitoring, these conditions can reduce cooling efficiency and potentially contribute to rising temperatures around critical equipment.
How Does Data Center Airflow Monitoring Work?
A Sensaphone air flow sensor can be added to any Sensaphone IMS system to monitor the presence or absence of airflow and provide immediate notification if airflow drops. This gives data center personnel early warning of a potential cooling or ventilation problem.
Larger data centers often require additional sensor information to identify changes that could affect cooling efficiency. Monitoring airflow at critical locations can help personnel identify cooling-system problems before they lead to excessive heat, reduced server performance or equipment shutdowns.
Data center airflow management also helps maintain a cleaner, more stable environment for servers and other IT equipment. Maintaining proper airflow can help reduce conditions that contribute to dust buildup and ensure that cooling air is delivered where it is needed.
Why Is Data Center Airflow Management Important?
The sooner you learn of a ventilation failure, the faster you can act to prevent reduced server performance, equipment damage and complete shutdowns. Adding airflow sensors to a data center airflow monitoring system provides continuous visibility into critical ventilation conditions and can alert personnel when airflow is interrupted.
When combined with temperature and other environmental sensors, airflow monitoring can provide a more complete picture of data center cooling conditions. This helps personnel detect problems with air delivery and cooling equipment before they escalate into conditions that threaten IT equipment.
Where Should Data Center Airflow Sensors Be Placed?
Sensor placement should focus on critical points in the cooling airflow path. Recommended locations include:
- Each cold air supply
- Each hot air return
Monitoring both supply and return airflow helps data center personnel quickly identify a loss of ventilation and take corrective action before cooling problems affect critical equipment.
