Enhancing Data Center Performance and Reliability with SMART’s Conformally Coated DDR5 RDIMMs for Liquid Immersion Cooling by Raghabendra Rout, Ph.D., New Product Engineer, SMART Modular Technologies Technical Brief
■As data centers face increasing demands for performance and energy efficiency, liquid immersion cooling has emerged as a promising solution. Liquid immersion cooling offers superior heat dissipation compared to traditional air cooling, allowing for higher density computing and improved energy efficiency. However, it also presents unique challenges for electronic components. SMART’s conformally coated DDR5 RDIMMs address these challenges, by providing a reliable memory solution which allow the memory modules to operate effectively in immersion-cooled servers.
■SMART Modular Technologies’ conformally coated DDR5 RDIMMs represent a significant advancement in memory solutions for liquid immersion-cooled data centers. By combining DDR5 performance with enhanced protection against the unique challenges of immersion environments, these modules enable data centers to push the boundaries of computing power while ensuring long-term durability and reliability at the same time. For data center operators looking to leverage the benefits of liquid immersion cooling, SMART’s RDIMMs offer a compelling solution that addresses key concerns around component longevity, performance, and maintenance costs.
■The conformal coating process significantly improves the durability of DDR5 RDIMMs in liquid immersion environments in several key ways:
▲Corrosion resistance: The coating shields sensitive electronic components from corrosive elements present in the immersion coolants. This protection extends the lifespan of the memory modules by preventing chemical interactions that could degrade materials like plastics and metals used in RDIMM modules.
▲Moisture ingress prevention: Conformal coating helps prevent the invasion of moisture, which is a critical factor in liquid immersion environments. By sealing out moisture, the coating reduces the risk of short circuits and other moisture-related failures.
▲Material compatibility: The conformal coating addresses concerns about material compatibility between RDIMMs and the dielectric fluids used in immersion cooling. It prevents potential chemical reactions that could lead to swelling, creep behavior, or other forms of material degradation.
▲Improved thermal stability: The coating provides excellent thermal stability, making these modules ideal for the consistent thermal environment of liquid immersion systems. This stability reduces the risk of thermal hotspots and enhances overall system reliability.
▲Long-term reliability: By protecting against various environmental factors, the conformal coating significantly enhances the long-term reliability of RDIMMs. This is crucial for data center applications where component longevity directly impacts operational costs and system uptime.
▲Reduced maintenance requirements: By protecting against corrosion and environmental factors, conformal coating leads to higher reliability and lower maintenance costs for data center operators.
▲High-performance DDR5 technology: These modules leverage the latest DDR5 technology, offering superior speed and efficiency for demanding workloads such as AI, machine learning, and high-performance computing.
▲Large memory capacity: With support for up to 256GB per module, SMART’s RDIMMs provide the substantial memory capacity required for data-intensive applications in modern data centers.
