Internal and external contaminants can put your data center at risk. Common outside sources of harmful particulates include construction dust, air pollution, pollen, and sea salt. Common inside sources include human hair, skin fibers, as well as lint and dust from clothing. Additional harmful contaminants come from the data center operation itself. For example, particles from floor tiles and CRAC units, along with sources such as cardboard and paper.
Knowing what lurks in your environment is the best prevention against downtime and equipment failure. Annual particulate testing should be part of your data center best practices.
DP Guardian tests according to ISO standard 14644, which limits particulate to 3,520,000 at .5 μm in an environment housing electronic equipment.
