uniquely applicable. Originally designed for business office applications, ECIA-364-1000 covers relatively mild, controlled environment use, such as devices within data centres. Although EIA-364 tests are recommendations
and not requirements, they have become industry standard and serve as the ALT guidelines for many manufacturers.
Challenges of ALT in
Liquid Environments While EIA-364 and other ALT standards provide clear reliability guidelines for traditional air environments, ALT for components used within liquid immersion cooling applications is much less defined. Challenging this is the fact that there are already more than a dozen proprietary dielectric liquids on the market, all performing differently. Does that mean a manufacturer needs to perform ALT for 12+ liquids in addition to air?Will different products need to be manufactured per medium? The Open Compute Project (OCP) Immersion
Project aims to answer these questions and more using input and insights from industry experts to form a working group devoted to liquid immersion cooling. While air cooling has been the traditional method to lower server temperatures in data centres, immersion cooling has proven more energy efficient and cost effective while requiring less space. Through the Immersion Project, OCP is working to establish standardised definitions, specifications, compatibility requirements and best practices for both immersion solutions and immersion-ready equipment.
Ideally, through the guidance of organisations
like OCP, manufacturers will be able to design one product that performs reliably across all liquid and air-cooled environments. For system architects and design engineers, this will simplify the BOM and minimise the risk of confusion and error. And engineers are excited to get ahead of the game. In fact, a recent Molex Reliability and Hardware Design Survey found that 51 per cent of the 756 respondents already strive to meet possible future industry reliability certifications and standards, in addition to current requirements.
Molex is Paving theWay to
More Reliable Data Centres As an industry pioneer in high-speed data centre applications, Molex invests heavily in ALT capabilities and is an active contributor to OCP, including the Immersion Project.We’re committed to ensuring reliable data centre performance no matter the medium, and our broad portfolio of interconnect solutions is designed to meet current and evolving EIA-364 and OCP guidelines.
