DELL 57840S 10 Gbps Quad-Port SFP+ PCI-E 3.0 x8 Network Card

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.

이 상품에 대한 질문

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.
