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

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.
