Data Centers

Real-time Monitoring of Air Ciculation Wherever it is Needed.

Today’s data centers contain a dense array of blade servers that must function reliably 24 x 7. A system failure can lead to a cascading series of expensive repair costs and catastrophic damages to data. An important aspect of effective server monitoring is proper heat management. Runaway temperatures can impact long-term reliability and therefore proper air flow must be ensured and should be monitored in real time.

Due to the high cost of hot-wire anenometers, server engineers oftentimes resort to thermist-based air velocity sensors built in-house. Even the simplest thermistor-based solutions, however, require engineering resources for proper integration. It is extremely challenging to differentiate between actual air flow and changes in ambient temperature or self-heating of components on the circuit board, resulting in erroneous output.

Posifa Technologies now makes it affordable, feasible, and easy to install air velocity sensors throughout a server farm. Unlike thermistors, Posifa’s air velocity sensors, based on its thermal flow sensor die, are minimally affected by ambient temperature changes in data center applications. Integration is made easy with both a three-pin, analog-output model, and a SMD, I2C digital output model. Real-time monitoring can now be implemented wherever it is needed.
