Dataguard Solutions announces the launch of Dataguardian™; the cure for zinc whiskers.
Zinc Whiskers and Data Center reliability
Data Centers often contain large amounts of galvanized (zinc plated) steel. The steel used for structural supports is galvanized to stop it from rusting, and thus introducing iron oxide flakes into the sensitive environment.
Zinc is one of several metals known to grow whiskers; the latency time for metal whisker growth may be days or years or decades, for reasons not-well-understood. Once started, growth may happen much faster than latency. These whiskers are long and light, and when they separate from the galvanized surface they are easily swept around the Data Center by the cooling air. As these whiskers are made of a conductive material (pure zinc) they are capable of shorting components within the computers, causing random, often unexplained, failures.
This phenomenon while not fully understood is very well documented. Further details may be found on the NASA site here: https://nepp.nasa.gov/Whisker/other_whisker/index.htm .
Dataguardian™ is a coating that may be applied to virtually any non-electrical surface in a Data Center. It is particularly intended for application to the galvanized (zinc plated) steel structures comprising the raised floors, cable trays and clamps beneath, racks and air handling systems. It may even be applied to the galvanized housings used to hold computers, routers and other sensitive electronic equipment. Zinc whiskers that may be present on the galvanized steel do not need to be removed first. Whiskers that are present will be contained by the application of the coating, as will new whiskers that may grow or old whiskers that continue to grow.
The Dataguardian™ coating is a waterborne, mold resistant, non-hazardous product similar in nature to latex paint. It is designed to be applied by brush, roller or spray equipment. It may be applied to new galvanized surfaces at manufacture, or to old galvanized surfaces in the Data Center. If it is applied to a galvanized surface with existing zinc whiskers, it will encapsulate them completely.
A single coat of Dataguardian™ is sufficient to fully captivate over 99.9% of zinc whiskers for a period of 20 years or more.
Dataguardian™ has a naturally tacky surface once dry which tends to acquire airborne zinc whiskers. This offers enhanced protection in instances where it has not been possible to obtain 100% coverage of galvanized surfaces in the Data Center.
Dataguardian™ was developed subsequent to research funded by the US Missile Defense Agency for the captivation and containment of Tin whiskers. Tin whiskers are a global problem following the RoHS legislation introduced by Europe which removed lead from solder. Dataguardian™ is formulated to captivate zinc whiskers and is not suitable as an electronic conformal coating to captivate tin whiskers on circuit boards.
The Optimal Solution
Historically Data Centers that suffered from Zinc Whiskers left their operators with a choice between:
- Remediation: Regular deep cleaning to minimize the disruption and outages caused by zinc whiskers
- Cure: Decommissioning and replacement of the Data Center with its extreme cost
Now, Dataguardian™ is available to provide a highly cost effective alternative to decommissioning a Data Center while offering a permanent solution to the problems of zinc whiskers. It is now possible to cure zinc whiskers with a remediation budget, offering enormous environmental and financial benefits compared to decommissioning a contaminated Data Center.
