Degradation of Metal Components in IT Equipment due to Arial Contamination is known as Air Corrosion,which leads to multiple Technical and Operational Problems. To know more about the Impact of Air Corrosion on Data Center Kindly View the PPT andif in case any queries get back to us.

Air Corrosion Monitoring
in Data Centre

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. 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. 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. 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. 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

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. 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. 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. 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. 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. 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. 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. 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. Four Levels of Corrosion Severity

Extremely High rate of

would be expected to
survive.

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
