Axiom 665249-B21-AX 10Gb dual-port SFP+ PCIe 2.0 x8 network card

SKU CH-PP9P-VRYGS MPN 665249-B21-AX

Dual-port 10Gb SFP+ PCIe 2.0 x8 card with optical-fibre connectivity for servers

  • Product weight0.24
  • Dual 10Gb SFP+ ports deliver high-speed server connectivity
  • PCI Express 2.0 x8 host interface provides ample bandwidth
  • Low-profile 6.5" × 2.7" × 0.5" form factor fits dense chassis
  • Lightweight 3.84 oz design eases installation in rack servers
  • Three-year limited warranty backs long-term reliability

Dual-port 10Gb SFP+ server NIC

The Axiom 665249-B21-AX provides two SFP+ ports for 10GBase-X optical networking in a PCI Express 2.0 x8 slot. It is built for server installations that need dual 10 Gb/s fibre links without moving to a newer bus generation.

Low-profile plug-in card with minimal draw

The card measures 6.5 by 2.7 by 0.5 inches and weighs 3.84 oz, fitting standard low-profile brackets. Passive cooling keeps noise at zero while power consumption stays within the PCIe 2.0 x8 slot budget during normal operation.

Steady throughput under continuous load

Dual ports maintain line-rate 10GBase-X traffic over extended transfers without thermal throttling. The plug-in form factor relies on chassis airflow, so sustained performance depends on server cooling capacity rather than onboard fans.

Questions about this item

How is the PCI Express 2.0 x8 card installed, and which step is often missed?

Insert the card into an available PCI Express 2.0 x8 slot, secure the bracket screw, then attach compatible SFP+ transceivers and fiber cables to the two ports; the step often missed is installing the transceivers before cabling.

What maintenance or replacement will the 10Gb dual-port SFP+ card need later?

The card itself has no moving parts; plan to replace SFP+ transceivers or fiber patch cords if links degrade, and reseat the card if the server is moved or upgraded.

What limit appears first on the 665249-B21-AX under sustained 10GBase-X traffic?

The PCI Express 2.0 x8 host interface caps sustained throughput at the lane bandwidth, so the bus becomes the bottleneck before the dual SFP+ ports reach their line rate.
