Application of infrared thermal imaging in blade system temperature monitoring

Abstract

All objects emit infrared radiation at differing levels, depending on their temperature. Infrared thermal imaging is the technique of producing an image from infrared radiation. This thermal image represents two-dimensional distribution of the infrared radiation emitted by object displaying the object's temperatures. High performance computing data centres deploy high-density blade servers that have high power and cooling requirements. Thermal management techniques are needed in different levels to ensure data centre's reliability and economical operating cost. Appropriately designed and accurate temperature monitoring is essential for every thermal management techniques. Infrared thermal imaging can provide a fine-resolution thermal image of blade systems deployed in data canter. This paper outlines an application of infrared thermal imaging in blade based data centres. For this purpose thermal monitoring of computer cluster at the blade-level is conducted using infrared thermal imaging monitoring system at the blade enclosure-level.
