Maximizing the life of the server, storage, and other electronic equipment within the data center is bound to increase the operational efficiency and add value to the organization, even though the IT equipment life cycle may be as short as three years. UPS, servers, hard drives and other sensitive electronic equipment failures are on the increase in sites where stringent airborne contamination policies are not in place.
Many locations, which are essential for bandwidth and latency requirements of the business, are either within highly populated areas with heightened pollution levels, or on industrial parks where neighboring businesses may generate pollutants, which then contaminate the data center.
Sites, where the server environment is maintained at a high temperature, must be monitored for changes in humidity, especially if fluctuations in server-load create variation in temperature. Variable humidity increases the corrosion risk, where contaminants absorb moisture and settle on electronic devices.
The following factors should be taken care of to prevent the corrosion of data in the Corporate Companies.
- Assessment of the outdoor air and indoor environment with attention to corrosion potential. ISA Standard 71.04-2013 should be used to provide site-specific data concerning the types and level of gaseous contaminants in the corrosion being formed. An initial survey should be carried out using copper and silver corrosion classification coupons to establish baseline levels of total corrosion and identify individual corrosive species in the air. This information can be used to develop a contamination control strategy and determine if and what type of air cleaning may be required to eliminate the potential for damage to sensitive electronic devices.
- Contamination control strategy, for this to be successful it is essential to understand the chemical contaminants in the indoor environment. Then the selection of an appropriate chemical filtration system to clean both incoming air, being used for pressurization or ventilation, as well as recycled air can be effectively undertaken.
- Real-time environmental monitoring, based on ISA Standard 71.04 severity levels. Measurement of airborne corrosive in a data center can be calculated using a method called ‘reactivity monitoring’. This requires the monitoring and analysis of copper and silver corrosion rates using specially prepared copper and silver sensors that correlate to ISA severity levels for equipment reliability. The use of silver reactivity monitoring as part of the assessment is required to provide a complete record of the type of corrosive chemical classes in the data center environment. This provides the data to select the appropriate filtration solution for that area.
- Specifically positioned real-time atmospheric corrosion monitors will provide accurate data on the performance of the chemical filtration system, if required, and allow the room air quality to be maintained, protecting the sensitive electronic systems.
ASHRAE, together with a number of computer systems manufacturers, has developed guidelines to assist data center operators in implementing contamination solutions that complement equipment warranty requirements.
It is important as a Corporate Company to not neglect the importance of this issue. The most simple yet effective solution to this issue is having air testing done regularly throughout the year. Indoor Air Quality Testing can be done from a NABL Accredited Lab in your vicinity.
Do not let IAQ affect the data centers in your organisation. Prevent your data with effective measures and improve the efficiency of your work.
