Lenovo ThinkSystem Mellanox ConnectX-5 EN 10/25Gb 2-Port SFP28 PCIe Ethernet Adapter

ConnectX-5 EN is the controller family of the Lenovo ThinkSystem Mellanox ConnectX-5 EN 10/25Gb 2-Port SFP28 PCIe Ethernet Adapter, part number 4XC7A62574. It has two SFP28 ports rated at 10/25Gb and installs in a PCIe slot.

This controller sits a generation above ConnectX-4 Lx. If a server was built with ConnectX-5 EN, replacing it with the same family keeps drivers and firmware tools consistent, which is the main reason to choose this part number over a similar-looking card.

Two ports at dual speed let the card connect to 10Gb switches now and 25Gb switches after an upgrade. They also give you a redundant pair or a split between two networks. SFP28 optics and direct attach cables are bought separately.

The controller is named Mellanox in the product title. Other cards in the ThinkSystem range that offer the same port layout use controllers from Intel, Broadcom or Marvell, and each brings its own driver set.

Offers are refurbished and used. Refurbished cards carry a warranty choice of 1 year or 3 years, and used cards carry 90 days. No new offer is listed. Send your quantity and server model with your request.
