DELL 540-BCXP Mellanox ConnectX-6 DX 100GbE QSFP56 dual port network card

SKU CH-EQHE-8W6VG MPN 540-BCXP

Dual-port 100GbE QSFP56 adapter adds high-speed fibre connectivity to servers via PCI Express

  • Rated speed100 Gbit/s
  • Dual 100 Gbps ports for high-throughput server links
  • PCIe plug-in card installs quickly in standard slots
  • Mellanox ConnectX-6 DX controller drives low-latency networking
  • Optical-fiber QSFP56 connectivity spans long-distance data-centre runs
  • Full-height bracket fits common rackmount chassis configurations

Dual-Port 100GbE Adapter

The Dell 540-BCXP is a Mellanox ConnectX-6 DX network card built for servers and workstations that require dual-port 100GbE connectivity over optical fibre. It installs in a standard PCI Express slot using a full-height bracket. Two QSFP56 cages accept compatible transceivers for high-speed links.

100Gbps Optical Throughput

Each port delivers up to 100Gbps via 100GBase-X signalling over optical fibre, enabling long-distance runs between rack equipment. The dual-port layout doubles aggregate bandwidth for clustering, storage replication or backbone uplinks without occupying additional expansion slots.

Suits High-Density Server Builds

This card fits administrators deploying 100GbE spine-leaf fabrics or high-performance compute clusters that need two optical ports in a single full-height bracket. It does not suit workstations limited to low-profile brackets, copper DAC cabling or single-port 100GbE requirements.

Questions about this item

What throughput can I expect from the 100 Gbps rating once the card is installed in a server?

The adapter delivers up to 100 Gbps per port over 100GBase-X optical links, so each QSFP56 port can sustain line-rate 100 gigabit Ethernet traffic in a real machine.

Which PCIe interface does the card use and what bandwidth ceiling does that impose?

It plugs into a PCI Express slot; the supplier notes a 250 MB/s bandwidth PCI Express adapter, indicating the practical host-interface ceiling for this model.

What physical slot and bracket height does the card need to fit?

The card is a full-height plug-in card with a full-height bracket, so it requires a standard full-height PCIe slot in the server or workstation chassis.
