Raritan® — a brand of Legrand® has introduced new monitoring sensors to provide data center operators an accurate picture of environments at the rack, aisle, and facility level, and of potential risks. Raritan's new SmartSensors™ can monitor a cabinet’s temperature, humidity, airflow, and air pressure — as well as detect water/leaks, vibrations, and unauthorized openings of cabinet doors.
With compute loads and deployments of double-digit kW cabinets on the rise, accurate monitoring of environmental dynamics is necessary to provide safe conditions for servers to operate. Raritan’s next-generation environmental sensors provide the industry’s highest metering accuracy at +/- 0.5 °C for temperature sensors and +/- 2.5% for relative humidity sensors.
SmartSensors come in different configurations – such as a combined temperature and humidity sensor – to make it easy to measure the cold and hot aisles, and position the sensors top, middle, and bottom in the cabinet -- as recommended by ASHRAE. Raritan also offers SmartSensors that detect water leaks and vibrations. For security, contact closure sensors are available to monitor cabinet door openings/closings.
The collected sensor data helps to reveal trends over time. For additional insight, information gathered by sensors can be monitored and analyzed by DCIM (Data Center Infrastructure Management) software for tracking trends and generating reports. Users, for example, can on a dashboard compare the data from sensors to the environmental envelope of a psychrometric chart to ensure that adequate cooling is where it needs to be.
SmartSensor Benefits
- Save on cooling by confidently raising data center temperatures.
- Check airflow and air pressure to and from racks to prevent hot spots and bypass recirculation.
- Make strategic decisions on cooling design and containment.
- Set thresholds and alerts to monitor on-site and remote facilities.
- Improve data center uptime by receiving alerts for any fault conditions.
Without disrupting operations, Raritan’s plug-and-play SmartSensors can be installed into Raritan’s PX® intelligent PDUs thereby cost effectively leveraging the existing network layer in racks provided by the PDUs. The sensors also can be deployed as plug-and-play options for Raritan’s EMX rack controllers, PX inline meters, rack transfer switches, and branch circuit monitors. Removable sensor heads are available to help maintain the accuracy of the temperature/humidity sensors.
