O3425G4I81 25G Ethernet OCP NIC 3.0 Card Intel® Based

Quad port 25 Gigabit Ethernet OCP NIC 3.0 Card Intel® Based

Silicom’s 25 Gigabit Ethernet OCP NIC 3.0 are designed for Servers and high-end appliances. The Silicom 25 Gigabit Ethernet OCP NIC 3.0 offer simple integration into PCI Express x16 to 25Gigabit Networks. The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications.

The Silicom 25 Gigabit Ethernet OCP NIC 3.0 are based on Intel E810-CAM1 Ethernet controller with fully integrated 25 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 25 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.
