GIGABYTE 25GbE SFP28 LAN Add On Card
GIGABYTE’s CLN4C44 quad-port LAN add on card features dual Mellanox ConnectX-4 Lx EN network controllers, providing 25Gb/s Ethernet connectivity to address virtualized infrastructure challenges for today’s demanding markets and applications. Providing true hardware-based I/O isolation with unmatched scalability and efficiency, the ConnectX-4 Lx controller provides a cost-effective and flexible Ethernet adapter solution for hyperscale, cloud infrastructures, enterprise datacenters and more, delivering best- in-class performance with smart offloading.
Overlay Networks Support (VXLAN / NVGRE / GENEVE)
In order to better scale their networks, data center operators often create overlay networks that carry traffic from individual virtual machines over logical tunnels in encapsulated formats such as NVGRE and VXLAN. While this solves network scalability issues, it hides the TCP packet from the hardware offloading engines, placing higher loads on the host CPU. The ConnectX-4 Lx EN controllers on GIGABYTE’s CLN4C44 effectively address this by providing advanced NVGRE, VXLAN and GENEVE hardware offloading engines that encapsulate and de-capsulate the overlay protocol headers, enabling the traditional offloads to be performed on the encapsulated traffic for these and other tunneling protocols (MPLS, QinQ, and so on). With ConnectX-4 Lx EN, data center operators can achieve native performance in the new network architecture.
