GIGABYTE 25GbE SFP28 LAN OCP Type Card

GIGABYTE’s CLNOQ42 dual-port LAN add on card features a Marvell FastLinQ 41202-A2G network controller, providing 25GbE Ethernet connectivity in a compact OCP Type 1 form factor card ideal to use with GIGABYTE’s server products that have an OCP mezzanine slot.

Marvell’s FastLinQ 41000 Series network controllers provide exceptional value in delivering industry-leading features and performance to enable the most efficient and agile software-defined data centers (SDDNs). Designed for the most demanding server and network virtualized environments, the 41000 series adapters enable Universal RDMA (RoCE and iWARP) as well as NPAR, VXLAN/NVGRE/GENEVE, and SR-IOV to boost server CPU efficiency and maximize application performance.


Overlay Networks Support (VXLAN / NVGRE / GENEVE / GRE)

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 FastLinQ 41202-A2G controller on GIGABYTE’s CLNOQ42 effectively addresses this by providing advanced NVGRE, VXLAN, GENEVE and GRE 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).
