Battery-free RFID sensor tags enhance DCIM system


Farsens' passive RFID tags and sensors, which do not require batteries, have been used by EPC Solutions Taiwan to augment its DCIM (Data Centre Infrastructure Management) system. The RFID tags remotely monitor asset temperature, pressure and humidity of data centre equipment.

The battery-free RFID sensor tags are integrated into the intelligent DCIM system alongside a patented flexible antenna. Providing assets inventory status and location, the system monitors environmental temperature, humidity and pressure on a real time basis for the data centre. Upon detecting abnormal parameters, the system will immediately start the backup facility and alert maintenance and operation personnel with notification messages and related records, information which will also be sent to any other related processing units.

Processing requirements and power-hungry equipment mean that energy bills are a primary cost of data centre administraton. The increased OpEx can easily exceed the hardware cost of the server during its operational lifespan, necessitating tools such as DCIM or thermal monitoring systems, essential for controlling overhead costs and improving efficiency.

The ablilty to control temperature in real time can significantly impact an energy budget, giving an estimated energy saving of 1% per °C that the required AC temperature can be raised.

“We were able to easily integrate Farsens’ RFID sensors in our systems without having to implement custom software or proprietary hardware, which allows us to leverage the existing infrastructure” commented Edward Sung, Vice President, EPC.
