Axiom

Axiom 593717-B21-AX 10Gb dual-port SFP+ PCIe 2.0 x8 network card

SKU CH-RKT4-VCM1A MPN 593717-B21-AX

Adds two 10 Gb SFP+ ports via a PCIe 2.0 x8 slot for HP 593717-B21 server networking

  • Weight0.24
  • 10 Gb dual-port SFP+ connectivity for high-speed server links
  • PCI Express 2.0 x8 host interface delivers full bandwidth to the bus
  • Low-profile 6.5" × .5" × 2.7" form factor fits dense chassis
  • Light 3.84 oz weight reduces load on the motherboard
  • Three-year limited warranty backs long-term deployment

Dual 10Gb SFP+ server NIC

The Axiom 593717-B21-AX installs in a PCI Express 2.0 x8 slot and presents two SFP+ cages for optical 10GBase-X links. It targets administrators adding 10 Gb uplinks to rack-mount servers that still run generation-2 buses.

Low-profile plug-in card

Measuring 6.5" by 2.7" and just 0.5" tall, the card fits standard low-profile brackets and weighs 3.84 oz. Dual SFP+ ports accept compatible optical transceivers so cable type and reach are chosen per link rather than fixed at purchase.

PCIe 2.0 x8 bandwidth ceiling

The host interface tops out at the throughput of a 2.0 x8 connection, so sustained line rate on both 10 Gb ports simultaneously is not guaranteed. Buyers needing full bi-directional 10 Gb on each port should verify their platform can deliver the required lane bandwidth.

Questions about this item

What does the PCI Express 2.0 x8 interface mean for total throughput on this 593717-B21-AX card?

The PCI Express 2.0 x8 host interface provides enough bus bandwidth for both 10 Gb/s ports to operate at line rate simultaneously.

What are the physical dimensions of this Axiom 593717-B21-AX card so I can confirm it fits my server?

The card measures 6.5 inches in height, 0.5 inches in width and 2.7 inches in depth, weighing approximately 3.84 oz.

How do I install the SFP+ modules in this dual-port 10GBase-X card and what step is commonly missed?

Insert the card into a PCIe x8 slot, then insert SFP+ transceivers into the two SFP+ cages until they click; the step often missed is fully seating each transceiver until the latch engages.
