Air Corrosion


Published on

Degradation of Metal Components in IT Equipment due to Arial Contamination is known as Air Corrosion,which leads to multiple
Technical and Operational Problems.

Air Corrosion

  1. 1. Best Practices Awareness CampaignAir Corrosion Monitoring in Data Centre
  2. 2. Introduction of Equinox Labs• EQUINOX Labs is an ISO 9001:2008 Certified• State-of-the-art Laboratory for carrying out various tests in food, water, hygiene, air & environment Safety• EQUINOX comes with the assurance of providing prompt Accurate and reliable services• EQUINOX believe that Customer satisfaction is the first step towards a long lasting relationship
  3. 3. What is Air Corrosion?• Corrosion is the gradual destruction of material, usually metal, by chemical reaction with its immediate environment• Corrosion is a natural process which cannot be stopped, but intervention with correct measures can control it• Corrosion by Air (Gases) has largely been neglected in almost all IT and Data center companies, till recently• Extremely low levels of contaminant gases can cause corrosive damage to electronic equipment (IT and Computer Systems)
  4. 4. Symptoms in IT & Data Centre• Failures & Outages of Discrete Electronic Components & PCB Boards• Sporadic Circuit Failure• Lower Energy Efficiency of Installed IT Equipment• Inconsistency of Critical Data & Loss of Data• Requirement for Frequent Replacement of Damaged Electronic Components• Substantial Increase of Data Center Maintenance Costs
  5. 5. Who are Behind These Problems?• Environmental threats posed by Contaminant Gases, Airborne Particulates, Humidity & Temperature• Even low levels of contaminant gases can cause corrosive damage to electronic equipment• Contaminants, both internal & external (Gases) are responsible for causing problems related to Corrosion in the critical IT equipment• These gases seep into data processing facilities from outside air, and cause damage
  6. 6. Where does this Problem Occur?• Data Centers’• IT Companies & IT enabled services• BPOs’/KPOs’• Telecom Companies• News & Media• Semi-conductors• Distributed Control System (DCS)• Motor Control Centers and Switch Rooms of Petrochemical units
  7. 7. How Does Corrosion Occur?• Corrosion is defined as the deterioration of a base metal resulting from a reaction with its environment• In the context of electronic equipment, it refers to the reactions between the Copper and Silver surfaces that are present in the IT equipment• When corrosive gases along with water vapor come in contact with a base metal, the reactions result in various chemical products, thus permanently damaging the properties of the component parts Continued…
  8. 8. How Does Corrosion Occur• Corrosion on a thin film disk may have serious results• Because of accumulation of reaction products on the equipment, mechanical failures (head crashes, wear & tear) can occur on data tracks which were not corroded previously
  9. 9. Three Types of Corrosive Gases• Acidic Gases – – Hydrogen Sulfide (H2S) – Sulfur Oxides (SOX) – Chlorine (Cl2) – Nitrogen Oxides (NOX)• Alkaline (Caustic) Gases – Ammonia (NH3)• Oxidizing Gases – – Ozone (O3)
  10. 10. How Gases Generate?• External generation from auto emissions, heavy industrial pollution, heat and power generation• Offices are more prone to air pollution from gaseous airborne contamination if it is situated near: – Landfill sites – Sewerage / Drains – Swamp / Marshy Lands – High density traffic – Process Industry (emanating industrial effluents)• Contaminants are very often generated in Data Processing and Computer Printing Facilities
  11. 11. Understanding the Risk• Data centers are generally diversified across multiple geographical areas• Areas with higher atmospheric and air contamination requires greater attention into air quality management in data centers – Requirement of Air Side Economization• Major concern of Air Side Economization is the increase in the air contamination leading to corrosion of the metal components of the IT equipment
  12. 12. Understanding the Risk• Temperature Variation and Humidity act along with the gaseous contaminants, and potentially increase the threat of Air Corrosion• Ensuring that IT Equipment are exposed to minimum risk
  13. 13. What Are The Environmental Standard Formulated?• Standards specifying the type and concentration of airborne contaminants that computers could be exposed to were developed by The Instrument Society of America (ISA)• ISA standard defines or characterizes environments in terms of their overall corrosion potential• Quantitative measure of corrosion potential can be established by using “reactivity monitoring”
  14. 14. Steps Involved in ISA• Reactivity monitoring involves placing strips of copper metal, called Corrosion Classification Coupons, into an environment for 30 days• Coupons are then analyzed in a qualified laboratory to determine how much corrosion copper film formation in angstroms has occurred• Data is used determination for the corrosion severity level of the environment• Analyzed severity level refers to the potential damage that the corrosive gases in the air could cause
  15. 15. How to Measure the Corrosion?• Corrosion Management Strategy has three goals: – Measuring the Composition of the Air in the Data Centre – Establish the risk levels for the IT Equipment operated in the contaminated atmosphere (Metal Reactivity Monitoring) – Design strategies to mitigate Corrosion effects.• It has to be analyzed in the context of data center operating conditions
  16. 16. Four Levels of Corrosion Severity C la s s if ic a t io n o f R e a c t iv e E n v ir o n m e n t sS e v e r E n v ir o n m e C opper E q u ip m e n it y nta l E n v ir o n m e n t a l R e a c t iv it y tL e v e l D e s c r ip t io R e lia b ilit y Le ve l L if e s n G1 Mild < 300 Corrosion not a factor Normal G2 Moderate < 1000 Corrosion may be a factor < 5 Years High possibility of attack of Corrosion. Evaluate G3 Harsh < 2000 < 2 Years Environmental Monitoring & Control. Extremely High rate of Corrosion. Only designed GX Severe > 2000 packaged equipment < 1 Year would be expected to survive.
  17. 17. When Monitoring Should be done?• Before selection of site for setting up Data Centre• After construction of the building structure• After Setting up of the Data Centre Infrastructure, prior to commissioning• Post commissioning, once every quarter, since Air quality changes every time along with seasons
