INDUSTRY INTELLIGENCE POWERED BY THE DCA Zinc whiskers and noticing if your server room or data centre is at risk Zinc whiskers are microscopic, crystalline slivers of zinc that form through corrosion. Whiskering can originate from any number of sources; flooring panels, duct work, ceiling hangers, server racks, electrical components and virtually any source galvanised with this brittle metal – even bolts, nuts and washers may exhibit signs of whiskering. hardware and cause extensive downtime. PCB boards and other pieces of electronic equipment (servers, SSDs, PCB boards, etc.) are all at risk of being affected by zinc whiskers. To neutralise the risks associated with zinc whiskers, Critical Facilities Solutions offers a complete solution that includes: • Sample collection and analysis • Laboratory testing • Remediation • Specialist cleaning • Testing and consultancy Getting started with professional cleaning doesn’t have to be difficult. If you’re new to the concept of hiring specialists to clean your critical facility, a professional data centre cleaner can walk you through the entire process, explaining each step and making recommendations along the way. Since no two facilities are the same, it is highly recommended that a thorough While it is now fairly well understood how whiskering occurs, tracing the source isn’t always so easy. For one, these ‘whiskers’ are incredibly light which means they can easily travel through HVAC systems and subfloor voids. These metallic, fibre-like ‘whiskers’ are highly conductive and can cross circuit board traces, corrupt data, compromise Since no two facilities are the same, it is highly recommended that a thorough inspection and survey be commissioned before you set out to create a service profile and schedule. inspection and survey be commissioned before you set out to create a service profile and schedule. Following a consultation, it is highly likely that a full deep clean will be recommend as the starting point for any ongoing maintenance cleaning (especially if your facility has never received a professional service, or if there has been a lapse in cleaning). A deep clean may include cleaning every square inch of the data hall, equipment surfaces, as well as flooring, stringers, pedestals and the sub-floor voids. These aren’t ‘precautionary steps’, but essential parts of preventing recontamination and ensuring your facility is as dust- and contaminationfree as possible. Selecting the best ‘starting point’ for your data centre’s maintenance regime can prove challenging. The Data Centre Alliance (DCA) has, in consultation with the leading UK Data Centre cleaning authorities and companies, produced and distributed an Anti-Contamination Guide which focuses on best practice and should be considered a great resource in determining your starting point for any maintenance schedule. ◊ www.intelligentdatacentres.com Issue 17 23
