INDUSTRY INTELLIGENCE POWERED BY THE DCA Maintaining your data centre should take a ‘minimise, regulate and maintain’ approach to contamination control and cleaning. are twofold; firstly, it’s a snapshot in time and; secondly, it only measures contaminates that are airborne and not those that have already settled. There have been significant new advancements in the equipment and methods used to test the air quality and the volume of particulate in the air. At Critical Facilities Solutions, we are introducing new methods of testing. While we still use hand-held, snapshot, air particle testing where necessary and relevant, we are also installing robust, cost-effective alternatives that when taking the test parameters of the ISO standard and integration into data centre systems into account. Settled contaminants cause decreased performance and thermal clogging. When airborne or touch contaminants build up on the surface of equipment, this is known as ‘settled contamination’. These tiny particles make their way onto (and into) delicate equipment, resulting in thermal clogging, data loss and performance bottlenecks due to thermal throttling. Contaminationrelated failures can even occur with solidstate drives (SSDs). Densely packed racks are more susceptible to contamination. Servers and drives continue to shrink and become even more compact. This is great for reducing floor space but it also means equipment is packed in tightly, creating opportunities for settle contaminants to go unnoticed. It’s important to note that the more contamination accumulates on equipment and in air filters, the less efficient equipment becomes, leading to performance bottlenecks and wasted energy mostly down to the additional cooling requirements which then lead to further environmental impact. On to lesser known risks, but for those that have experienced it firsthand, the threat of zinc whiskers – and how they cripple essential equipment – is very real. But, there are several factors that are making this once-rare phenomenon all the more common. Mike Meyer, Managing Director at Critical Facilities Solutions UK measure the air quality on a constant or predetermined basis. We’ve coined the phrase ‘Constant Air Monitoring’. The product and system we supply and install can operate as a standalone system or be integrated into any BMS system. While Continuous Particulate Air Monitors (CPAMs) have been used for years in nuclear facilities to assess airborne particulate radioactivity (APR) and pharmaceutical cleanrooms to measure air particulate (AP), the CPAMs have typically been extremely costly to install in other environments.
