The nVidia Mellanox MCX456A-ECAT ConnectX-4 is a low-profile PCIe interface card designed by Mellanox. It features two QSFP28 ports supporting 100 Gbps transmission speed per port, offering high-throughput connectivity for data-intensive applications.
This dual-port adapter supports standard PCI Express Gen3 x16 and operates in compatible servers requiring high-bandwidth Ethernet connections. The unit accepts fiber transceivers via its QSFP28 interfaces and uses active cooling with an onboard heatsink to manage thermal output during sustained operation. Rear bracket mounting enables integration into rack-mounted chassis or server systems as required by deployment configurations.
