Mellanox Technologies MCX516A-CDAT Network Interface Card

The Mellanox ConnectX-5 MCX516A-CDAT is a dual-port 100 GbE network interface card (NIC) that plugs into a PCIe Gen4.0 slot and uses QSFP28 ports for fiber connectivity. Built for data centers and high‑performance servers, it provides two independent 100 GbE Ethernet interfaces to handle demanding workloads and dense network topologies. The PCIe Gen4.0 host interface delivers the bandwidth needed for network‑intensive operations, while the dual QSFP28 ports enable scalable, high‑throughput connections from a single card to 100 GbE networks. As part of the Mellanox ConnectX-5 family, the MCX516A-CDAT is designed for enterprise deployments that require reliable, high‑speed connectivity for server and storage‑network workloads. Compatible with standard PCIe server platforms, this NIC is suited to data center applications that demand robust 100 GbE performance from a single expansion card.
