Hardware Protection… Dust, Temperature, and Humidity – Oh My! – Part V

Decreasing computer hardware replacement cost has not eliminated the need for adequate environmental protection. To avoid humidity corruption, information security managers should verify humidity and temperature levels are maintained within the operating range specified in supplier documentation for deployed IT. Periodically, an information security professional should inspect for obvious external influences such as close placement to air conditioners, elevator shafts, industrial equipment or other sources of potential atmospheric variations. If a high level of reliability is required, then optimal conditions should be maintained. Maintaining equipment at the optimum climate range aids in protecting hardware from corrosion problems associated with high humidity levels and failures caused by static discharge when humidity is too low.

IT can, and does, operate within a wide humidity range. Seasonal humidity changes are usually easier to control than hourly fluctuations. Under either circumstance, normally the primary environmental concern is preventing conditions that permit humidity alterations where condensation is the result. Data culled from analysis of historical psychrometer reading can be instrumental in determining seasonal changes or outside influences. Technically, a psychrometer is a hydrometer consisting of two thermometers with bulbs, one wet and one dry. One bulb is kept wet so the cooling that results from evaporation permits registration of a lower temperature than the dry bulb. The difference between the two readings constitutes a measure of atmospheric dryness.

When the relative humidity is high, water particulates are formed corresponding to the heat index. High humidity can warp hardware configuration cards. In addition, without adequate insulation, any conditions that cause moisture to be deposited on equipment will eventually depreciate hardware functionality. Maintaining the optimal temperature and humidity enable planning minimum user impact responses to hardware configuration item failures.
