Compare 10Gb Ethernet network cards for compatible servers, including adapters with SFP+ connections and models described by their copper-interface product families. Choose by the exact part number, connection type, port count and mounting arrangement. This collection is for network interface cards; an SFP transceiver, a Fibre Channel card or a 25Gb-only adapter is a different item.

Check how the card connects to your server

Confirm the required adapter form factor before ordering. A standard PCIe card, a platform-specific module and a server's dedicated network-adapter option need separate compatibility checks. Match the available slot and mounting arrangement to the exact product. A low-profile or full-height bracket is also part of the installation requirement, not just a description of the server chassis.

Check the supported operating system, driver and firmware for the selected part number. If the deployment needs particular offload, virtualisation or boot features, verify them in the adapter's documentation. The advertised link rate does not establish support for every software feature or guarantee a particular file-transfer speed.

Compare adapter listings

These examples use the adapter names and bracket suffixes stated in the product titles. Confirm the actual bracket supplied on the product page or in your enquiry. The SFP+ entries require a separate check of the supported transceiver or direct-attach cable and the equipment at the other end.

Part number	Listed adapter	Listed port count	Listing bracket suffix
656596-B21-HP	530T	Dual port	HPB
817738-B21-HP	562T	Dual port	HPB
807N9-LP	QL41112 SFP+	Dual port	LPB
GMW01-HP	Broadcom 57412 SFP+	Dual port	HPB
P11338-B21-HP	548SFP+	Two port	HPB

Plan the connection at both ends

Confirm that the switch port, cable or optical module and adapter are suitable for the intended 10Gb Ethernet link. Do not choose a transceiver by connector appearance alone. For copper connections, check the port type and cabling requirements for the exact hardware. For adapters offering several link rates, confirm support for your chosen rate and connection method.

For a multi-port installation, state the number of connections required and how the network will be configured. Several ports do not by themselves promise a single faster transfer. Check any teaming, redundancy or aggregation requirements against the operating system and switch configuration before deployment.
