25GBase-X Network Interface Card

This Lenovo network interface card provides a 25GBase-X connection for wired networking. It is built for servers and workstations that require 25 gigabit Ethernet throughput. The card installs into a compatible expansion slot to add high-speed network capability.

Suited for 25 gigabit infrastructure

This card suits administrators upgrading rack-mounted hosts to 25 GbE links. It is not for systems that lack a compatible high-speed slot or that operate solely on slower Ethernet standards. Buyers needing fibre-channel or InfiniBand connectivity should look elsewhere.

25GBase-X speed rating

The decisive specification is the 25GBase-X speed rating, which defines the signalling rate and encoding the card uses on the wire. Match this rating exactly to your switch ports and cabling plant before purchase.
