Acromag’s XMC631 module provides up to four 10-GbE interface ports. Different models are available for extended temperature operation and VITA 42/61 connector options to support a PCIe Gen 3 interface. Four SFP+ ports support optical or copper cabling. Intel’s XL710 quad-port 10-gigabit Ethernet controller delivers high-performance and offers many powerful networking capabilities. Advanced virtualization, intelligent offload and accelerator technologies optimize network performance. Combining the intelligent off-loading features of the XL710 controller with the processing power of a Xeon-D processor can deliver outstanding performance levels. Together, the two Intel devices provide a balanced hybrid solution of compute and off-load to achieve optimal performance and efficiency in an embedded system. Designed for COTS applications, these rugged XMC mezzanine modules offer a high-density, high-performance solution for network interface applications. They are ideal for use in defense, aerospace, industrial, and scientific research computing systems.
