O3CG2i81 100G OCP NIC 3.0 Card Intel® E810-CAM2 Based

Dual port 100 Gigabit Ethernet OCP NIC 3.0 Card Intel® E810-CAM2 Based

Silicom’s O3CG2i81 100 Gigabit Ethernet OCP NIC 3.0 is designed for Servers and high-end appliances. The Silicom 100 Gigabit Ethernet OCP NIC 3.0 offers 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 O3CG2i81 100 Gigabit Ethernet OCP NIC 3.0 is based on Intel® E810-CAM2 Ethernet controller with fully integrated 100 Gigabit Ethernet Media Access Control (MAC), and SFI Interface. In addition to managing MAC and PHY Ethernet layer functions, the controller manages PCI Express packet traffic across its transaction, link, and physical/logical layers. Using hardware acceleration, the controller offloads tasks from the host, such as TCP/UDP/IP checksum calculations and TCP segmentation.

Silicom’s O3CG2i81 100 Gigabit Ethernet OCP NIC 3.0 is the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.
