Mellanox MCX516A-CCAT 100GbE Dual-port QSFP28 PCIe 3.0 x16 expansion card

Network Interface Card 100GbE Dual Port

The Mellanox MCX516A-CCAT is a ConnectX-5 based network interface card delivering 100GbE throughput across two QSFP28 ports. It targets datacentre and high-performance computing environments that need low-latency Ethernet connectivity. The card installs in a PCIe 3.0 x16 slot and is supplied in new condition.

PCIe 3.0 x16 Slot QSFP28 Cabling

Integration requires an available PCIe 3.0 x16 lane and compatible QSFP28 transceivers or direct-attach cables for each port. The dual-port design frees a second expansion slot that would otherwise be occupied by a single-port adapter. Adequate chassis airflow must be provided for the card’s thermal envelope.

High-Density 100GbE Deployments

This adapter suits clusters, storage fabrics and hyper-scale workloads demanding 100GbE density in a half-height form factor. It is not intended for desktop PCs lacking PCIe 3.0 x16 bandwidth or QSFP28 cabling infrastructure. Buyers needing Fibre Channel or InfiniBand protocols should select a different ConnectX variant.
