O34CG2I81 100G OCP NIC 3.0 Card Intel® Based

Dual port 100 Gigabit Ethernet OCP NIC 3.0 Card Intel® Based

Silicom’s 100 Gigabit Ethernet OCP NIC 3.0 are designed for Servers and high-end appliances. The Silicom 100 Gigabit Ethernet OCP NIC 3.0 offer simple integration into PCI Express X16 to 100Gigabit Networks. The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications.

The Silicom 100 Gigabit Ethernet OCP NIC 3.0 are based on Intel E810-CAM2 Ethernet controller with fully integrated two 100G Ethernet Ports, enhanced programmable packet processing pipeline, virtualization (Enhanced SR-IOV support with up to 256 VFs, backward compatibility VF driver support), new features for the communications market (fine grained scheduler, transmit head drop support, adjustment of credits according to different headers, enhanced QoS, enhanced burst control) and RDMA (iWARP and RoCEv2).

Silicom’s 100 Gigabit Ethernet OCP NIC 3.0 are the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.
