Benefits of 6U Form-Factor in VPX Systems

This white paper discusses the advantages of the 6U form-factor in the context of OpenVPX systems, particularly compared to the more commonly used 3U form-factor. It outlines how the 6U format offers enhanced compute density, data bandwidth, and overall efficiency for various applications, especially in high-performance computing scenarios. The paper highlights recent advancements in cooling standards for 6U systems, which mitigate previous limitations associated with conduction-cooled modules. It also emphasizes the importance of considering both 3U and 6U options to meet diverse use cases in the embedded computing industry, ranging from low to high-performance applications. The document details specific use cases, including communications and sensor applications, and provides a comparative analysis of I/O efficiencies between the two form-factors. By presenting these findings, the paper aims to encourage designers to rethink their reliance on 3U modules and consider the potential benefits of 6U configurations for optimized design architectures.
