MT27711A0-FDCF-BEM, Mellanox ConnectX-4 Lx Network Card, 1-port 40GbE/PCIe 3.0 x8/Multi-Host

The Mellanox NVIDIA Mellanox MT27711A0-FDCF-BEM is a high-performance Ethernet controller IC from the ConnectX-4 Lx EN family, designed for demanding data center and enterprise server platforms. This single-port controller delivers up to 40 GbE connectivity over a PCI Express 3.0 x8 host interface, making it suitable for high-throughput workloads, virtualized environments, and modern cloud-native applications. With its efficient 8 GT/s PCIe signaling rate, the NVIDIA Mellanox MT27711A0-FDCF-BEM helps reduce bottlenecks between the network and CPU, so your infrastructure can handle heavy east–west and north–south traffic with consistent throughput.

The NVIDIA Mellanox MT27711A0-FDCF-BEM supports Multi-Host operation, allowing multiple hosts or CPUs to share a single Ethernet controller IC while maintaining traffic isolation and predictable performance. This capability is valuable for hyperscale and multi-tenant environments where density, cost control, and simplified cabling are key design targets. As part of the ConnectX-4 Lx EN family, it is optimized for Ethernet-based deployments that demand low latency and reliable packet delivery, helping operators in Asia, Europe, Africa, and North America build efficient, scalable networks.

Integrators and OEMs can embed the single-port Ethernet controller IC into custom server boards, appliances, or storage platforms to provide high-speed 40 GbE uplinks without adding standalone adapter cards. Distributors benefit from a compact, well-defined component that fits a wide range of next-generation hardware designs, while end users gain stable, high-bandwidth connectivity for virtualization, storage traffic, and clustered applications. When you select the NVIDIA Mellanox MT27711A0-FDCF-BEM, you get a proven Ethernet controller IC that aligns with modern data center architectures and supports long-term infrastructure planning.
