Mellanox 100GbE QSFP28 Network Card – MCX516A-CDAT

Specification

Product Description

The Mellanox MCX516A-CDAT, part of the ConnectX-5 EN adapter family, is a high-performance dual-port 100GbE network interface card designed for next-generation data centers and enterprise environments. Featuring dual QSFP28 ports, this NIC delivers an aggregate throughput of up to 200Gbps over a PCIe 3.0 x16 interface, ensuring exceptional bandwidth for high-volume traffic, storage, and compute-intensive applications.

Built for performance and efficiency, the MCX516A-CDAT supports advanced features such as Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE) and iWARP, which significantly reduce latency and CPU overhead. It also supports encapsulation offloads like VXLAN, NVGRE, and GENEVE, making it ideal for virtualized and cloud-scale deployments.

The card is optimized for use with a wide range of server platforms and is compatible with major operating systems, including Linux, Windows, and VMware ESXi. Its low-profile form factor and passive cooling design make it a versatile choice for dense server environments.

With hardware-level security enhancements, including secure boot and hardware root of trust, the MCX516A-CDAT ensures data protection and system integrity. Whether for high-performance computing (HPC), artificial intelligence (AI), or enterprise networking, this NIC delivers unmatched speed, reliability, and scalability.

🔑 Key Features:

• 100GbE Connectivity: Delivers blazing-fast 100Gbps Ethernet speeds over QSFP28, ideal for high-throughput applications.
• ConnectX-5 Controller: Powered by the advanced ConnectX-5 network controller for superior performance and reliability.
• PCIe Gen3/Gen4 Support: Compatible with both PCI Express Gen3 and Gen4 interfaces, ensuring maximum bandwidth.
