Dual-port 100G QSFP28 adapter

This PCIe network card provides two 100GbE QSFP28 ports for servers and workstations that need high-throughput wired connectivity. It is built on the Intel E810 controller and targets virtualised hosts, cloud nodes and storage clusters.

Capacity and headroom

The adapter negotiates at 1, 10, 25, 50 or 100GbE per port, giving headroom for heavy east-west traffic and RDMA workloads. A single x16 Gen 4 slot supplies the bus bandwidth; the card will fall back to Gen 3 if the platform does not support Gen 4.

Thermals, noise and power

Passive cooling keeps the card silent in normal rack airflow; power draw scales with link speed and traffic load. Both low-profile and full-height brackets are included so the card fits standard and ultra-thin chassis without modification.

Questions about this item

Will the Intel E810 card run at 100 GbE in a PCIe 3.0 x16 slot I already have?

Yes, the card is compatible with PCI Express 3.0 and will negotiate the link speed automatically, though maximum throughput may be limited by the 3.0 bus bandwidth.

How can I confirm both QSFP28 ports are linked at 100 GbE after installation?

Check the link status LEDs on the bracket and verify the negotiated speed in the OS network settings or with the Intel Ethernet Controller Tool.

Does the package include QSFP28 transceivers or cables, or must I buy them separately?

Only the adapter, a driver CD, and both low-profile and full-height brackets are included; QSFP28 modules or direct-attach cables are not supplied.
