Lenovo ThinkSystem Mellanox ConnectX-6 Dx 100GbE QSFP56 2-Port PCIe Ethernet Adapter

Two QSFP56 ports at 100GbE on a ConnectX-6 Dx controller define the Lenovo ThinkSystem Mellanox ConnectX-6 Dx 100GbE QSFP56 2-Port PCIe Ethernet Adapter, part number 4XC7A08248. It installs in a PCIe slot.

High-speed links like these are used where servers move a lot of data: storage nodes, virtualization clusters and build farms. Two ports allow redundant links to a pair of switches or a mix of storage and production traffic. QSFP56 cages need modules or cables rated for that form factor and for 100GbE, bought separately from the card.

The controller is listed under the Mellanox name in the title. ConnectX-6 Dx is a newer generation than ConnectX-4 and ConnectX-5, so it is often the choice for new builds at this speed.

Check the PCIe generation and width in the manufacturer's data against your server's slots before ordering. A card at this rate needs a wide, fast slot to use both ports fully.

The 4XC7A08248 is offered in new, refurbished and used condition. New and refurbished cards carry 1 year or 3 years of warranty, and used cards carry 90 days. Send your quantity and server model to request pricing.
