Axiom 10GBase-X dual-port SFP+ NIC

The Axiom 718904-B21-AX is a plug-in network interface card built for servers that need 10 Gbps fibre connectivity. It occupies a PCI Express 2.0 x8 slot and presents two SFP+ cages for optical modules.

Two SFP+ cages for optical fibre

The dual-port layout lets administrators run separate 10GBase-X links or aggregate them for redundancy without adding a second card. Optical media support means the card works with compatible SFP+ transceivers and fibre patch cables chosen for the required reach.

PCI Express 2.0 x8 bandwidth ceiling

The x8 Gen 2 interface supplies enough throughput for dual 10 Gbps line-rate traffic, but it cannot exceed the electrical limits of that generation. Servers restricted to x4 or Gen 1 slots would constrain total bandwidth below the card's rated capability.

Questions about this item

Will the SFP+ transceivers need replacing as optical modules age?

The card accepts standard SFP+ optical modules; transceiver replacement depends on the modules you install, not on the card itself.

Does the PCIe 2.0 x8 link saturate before the dual 10 Gb/s ports?

The x8 interface provides ample headroom for the combined 10 Gb/s throughput of both ports.

How much heat does the card add inside a server chassis running continuously?

The low-profile plug-in card draws minimal power and adds negligible heat in a server airflow path.
