The Mellanox ConnectX-5 EN MCX516A-CCAT is a high-performance, dual-port 100Gb/s Ethernet network card designed for demanding data center applications. This intelligent network card supports PCIe 4.0 and features advanced hardware offloads for networking, storage, and virtualization workloads. It delivers industry-leading throughput with ultra-low latency (750ns) and exceptional message rate performance (up to 200Mpps). The ConnectX-6 series predecessor, this nic card provides robust connectivity solutions for cloud, enterprise, and telco environments.
The ConnectX-5 EN network card incorporates several groundbreaking technologies:
This advanced nic card supports numerous industry standards including IEEE 802.3bj/bm/ba Ethernet standards, IEEE 802.1Q VLAN, and PCI-SIG PCIe 4.0 specifications.
The ConnectX-5 EN network card operates by offloading network processing tasks from the host CPU to specialized hardware on the adapter. Through its programmable pipeline architecture, the card handles packet processing, encapsulation/decapsulation of overlay networks (VXLAN, NVGRE, GENEVE), and storage protocol operations directly in hardware. The embedded PCIe switch enables efficient data movement between hosts and peripherals, while RDMA capabilities allow for direct memory access between systems, significantly reducing latency and CPU overhead. This sophisticated nic card represents the evolution toward the ConnectX-6 generation of adapters.
