SKU CH-QFCQ-V2W6G

Quad-port SFP+ adapter delivers four 10 Gbps Ethernet links over a PCIe 3.0 x8 slot

  • InterfacePCI-E 3.0 X8
  • 10 Gbps throughput per port for high-bandwidth workloads
  • Quad-port SFP+ design connects four links in one slot
  • PCIe 3.0 x8 interface supplies ample host bandwidth
  • Broadcom 57840S controller handles multi-queue traffic efficiently
  • Dell-engineered daughter card fits compatible server chassis

Dell 57840S Quad-Port 10 Gbps SFP+ Card

This new Dell network interface card adds four 10 Gbps SFP+ ports through a PCI Express 3.0 x8 slot. It is built as a daughter card for compatible Dell servers that need additional high-speed Ethernet connectivity.

Suits administrators expanding 10 Gbps links

IT teams adding multiple 10 Gbps connections to a qualified Dell server will use all four ports. Buyers who only need one or two ports will leave capacity unused, while anyone requiring a different port count, another form factor, or a card validated for non-Dell platforms should look elsewhere.

Interface is PCI Express 3.0 x8

The card occupies a single x8 slot running at the 3.0 generation. Verify that the target server provides an available x8 slot and that the system BIOS supports this daughter card before purchase.

Frågor om den här produkten

What SFP+ transceivers or direct-attach cables must I already have to use the four 10 Gbps ports on this 57840S card?

You need four SFP+ modules or DAC cables rated for 10 Gbps Ethernet; the card provides only the cages, so each port requires its own transceiver or cable to link to a switch or server.

Will this PCI-E 3.0 x8 adapter share bandwidth with an older PCI-E 2.0 x8 HBA I plan to keep in the same server?

Each slot negotiates its own link width and speed, so the 57840S will run at PCI-E 3.0 x8 while the older HBA stays at PCI-E 2.0 x8 without stealing lanes from the network card.

Which LED pattern on the quad-port bracket confirms every 10 Gbps link is up after I install the 57840S?

Each port has a link/activity LED; solid green means a 10 Gbps link is established and blinking shows traffic, so four steady greens indicate all ports are live.
