Lenovo ThinkSystem NVIDIA ConnectX-7 10/25GbE SFP28 4-Port PCIe Ethernet Adapter

Four SFP28 ports rated at 10/25GbE make the Lenovo ThinkSystem NVIDIA ConnectX-7 10/25GbE SFP28 4-Port PCIe Ethernet Adapter, part number 4XC7A99191, a high-density option for current ThinkSystem servers. The controller is NVIDIA ConnectX-7.

Dual-speed ports let the same card work with 10GbE switches now and 25GbE switches later, so a network upgrade does not force an adapter swap. Four ports in one slot also suit hosts that must keep storage, production, backup and management traffic on separate links.

The SFP28 cages take SFP28 modules or direct attach cables, which are bought separately. Confirm the optics your switches expect, and the speed each port will run at, before you finalize cabling.

Because this is the ConnectX-7 generation, it is the newest controller among the Lenovo SFP28 adapters here, which matters if your driver baseline is recent. This is the standard PCIe form.

We offer 4XC7A99191 in new, refurbished and used condition. New and refurbished cards carry 1 year or 3 years of warranty, and used cards carry 90 days. Include the quantity and server model in your request.
