Mellanox Technologies MCX314A-BCCT ConnectX-3 EN 56 Gigabit Ethernet network card

SKU CH-WKJQ-0K47Z

Dual-port 56 Gigabit Ethernet adapter with PCI Express 3.0 x8 interface for high-throughput server and storage workloads

  • Delivers 56 Gigabit Ethernet bandwidth for high-throughput server workloads
  • PCI Express 3.0 x8 interface enables low-latency data movement
  • Dual-port design supports I/O consolidation in virtualised environments
  • Integrated TCP/UDP/IP and iSCSI offload reduces CPU transport load
  • Compact PCB footprint with power-saving monitors lowers total system power usage

Single-port 56 GbE adapter for servers

The Mellanox ConnectX-3 EN MCX314A-BCCT is a single-port network card delivering 56 Gigabit Ethernet over a PCI Express 3.0 x8 interface. It targets enterprise servers and storage platforms that need high-throughput, low-latency connectivity for clustered databases, web infrastructure or high-frequency trading workloads. Integrated PHYs and a compact PCB suit blade and LAN-on-motherboard designs while power-saving features reduce total system draw.

Suited for PCIe 3.0 slots needing one 56 GbE link

This card fits builds that have an available PCI Express 3.0 x8 slot and require a single 56 GbE connection with TCP/UDP/IP and iSCSI offload. Buyers needing dual ports, a different port speed or a form factor other than a standard add-in card should look at something else. Environments without PCIe 3.0 support cannot use the adapter at its rated performance.

PCI Express 3.0 x8 interface decides compatibility

The adapter connects through a PCI Express 3.0 x8 edge connector, so the host system must provide that exact slot type and electrical width. Verifying the slot before purchase is the single specification that determines whether this is the right part.

Questions sur cet article

Does the MCX314A-BCCT fit a standard PCI Express 3.0 x8 slot?

Yes, the card uses a PCI Express 3.0 x8 edge connector and will seat in any compliant x8 or wider slot.

What is the common mistake when installing the ConnectX-3 EN adapter?

Inserting the card into an x4 or x1 slot, which mechanically fits but limits the link to four or one lanes and cuts the 56 Gigabit throughput.

When should the SFP+ transceivers in the dual ports be replaced?

Replace a transceiver if link lights fail, error counters climb, or the module runs unusually hot during sustained 56 Gigabit traffic.
