OE325G2I71 OCP Mezzanine Card Intel® XL710 Based

Dual Port 25 Gigabit Ethernet OCP Mezzanine Card

Silicom’s 25 Gigabit Ethernet Open Compute Project (OCP) mezzanine card is designed for use in any mother board that can utilize “OCP_Mezz 2.0_rev1.00” MEZZ cards.
The Silicom’s 25 Gigabit Ethernet OCP mezzanine dual 25 Gigabit Ethenet connectivity to the OCP Server node.

The Silicom 25 Gigabit Ethernet OCP mezzanine card is based on Intel XXV710 Ethernet controller with fully integrated 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.

OE325G2I71 OCP Card

The Silicom 25 Gigabit Ethernet OCP mezzanine card implement a type C NC-SI interface (single package, common bus buffers and shared RX queue).

Silicom’s 25 Gigabit Ethernet OCP Mezzanine cards is the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance OCP servers.
