Most data centers are well designed and are in areas with relatively clean environments, and most contamination is benign. Therefore, most data centers should not experience particulate or gaseous contamination-related IT equipment failures. However, according to the major IT equipment manufacturers, the number of data centers with contamination-related failures in the past ten years has increased significantly, though their number remains quite small. Much of the increase in the number of corrosion-related hardware failures is coming from the growth of server and storage system markets in Asia, particularly in China where the rapid industrial growth and the reliance on coal-fired power plants has heavily polluted the environment with sulfur-bearing gaseous contamination. This presentation will provide insight into the challenges faced by the IT industry in dealing with the hardware corrosion problems in the emerging markets in Asia and other unique industrial environments. Using outside air for cooling is considered the most straightforward way to reduce energy consumption in data centers, but it requires continuous monitoring of the air quality to preserve the reliability of IT equipment or more robust hardware. The corrosion mechanisms, the air monitoring techniques and the mitigation methods employed to contain the problem will be discussed.
