Data Centre : Server Failures due to Air Contaimantion

They could just do what the typical commercial and industrial application electronics manufactures do. Coat the whole circuit board in clear coat sealant. Its simple, cheap, and has been proven to be highly effective even with decades of usage in some applications.

The other option would be to go with a DIY approach and seal your own components before installing them. I have done that to many custom or modified circuit boards I have set up over the years that had to work in damp, humid, or highly variable environments.

I would find the source of the off gassing. If its been build or remodeled in the past few years the dry wall may be the problem.{Corrosive drywall} The data centers should be temperature and humidity controlled to help with moisture in the air.

As to the equipment conformal coatings may help in some cases. But replaceable/plugin boards and parts contacts can be problematic for protecting.

Another option would be seal the equipment in cabinets purge with an inert gas with slight positive pressure. Then use some method of cooling, heat exchangers or liquid coolers on some of the hottest components.

Though all the above does not solve the problem that started it. It only adds cost/complexity to the product.

Agreed ,but with respect to your comments , the equipments cost may get increased but one time cpex cost solution is better than the opex cost to maintain the air purification units plus additonal space requirement ..in my opionion best solution needs to be looked at the equipment end only.May be future technologies will provide some solution

The IT specialist's answer is, to relocate your server function to a remote site, and maintain a minimum onsite. Far cheaper, than hardening of your present hardware. And maintain minimal terminal hardware onsite. There is no cheap resistant solution.

Corrosive gas buildup in data centers might be fixed by exhausting instead of recirculating the air. Maybe air needs to be recirculated because it is part of an air cooling system. Forced air for heat rejection has a very low heat flux (~1 W/cm2) compared to liquid cooling, or, best of all, heat transfer by forced convection boiling (100 W/cm2). So it may be time for a fresh look at heat rejection.

Agreed , may be more in depth research needs to be done to consider this option.I guess by exhausting the heat , more energy needs to be spend to maintain the being open cycle air conditioning & freah air intake is required to create the possitive pressurisation.

For a price, and probably a big one, the IT manufacturers will build special purpose "hardened" systems that will withstand anything you specify! I remember many years ago a customer called with a problem and when we investigated, we found the server system was installed in a closet with toxic chemicals that were off gassing and it probably would have caused a much bigger problem if we have not pointed it out!

Thnx for your feedback.

If the specific large portion of a city is facing this problem & ambient air quality in that area is become corrosive in nature than what will be best soultion to handle this situation.

Due you have any idea about the major IT equipment suppliers i.e. Dell, HP , IBM, Sun, CISCO , Juniper etc have taken initative to tackle this problem at their end or just they recommonded to maintain the G1 standards as per ISA stds ..
