Product overview

The Dell 5J7H2 Mellanox MCX556A-ECAT ConnectX-5 VPI Adapter is a high-performance single-port network interface card designed for demanding datacenter environments. It supports data transfer rates up to 100Gbps, encompassing protocols such as GigE, 10GigE, 25GigE, 40GigE, 50GigE, 100GigE LAN, and 100Gigabit Infiniband. This VPI (Virtual Protocol Interconnect) adapter enables seamless switching between Ethernet and Infiniband modes, providing flexibility for HPC clusters, NVMe-oF storage fabrics, AI/ML training, and cloud-scale networking. Key benefits include ultra-low latency for east-west traffic, RDMA over Converged Ethernet (RoCE) support for reduced CPU overhead, and hardware offloads for better efficiency. Compatible with PCIe interfaces in enterprise servers, it ensures wire-speed performance without bottlenecks, making it essential for scale-out architectures where high bandwidth and reliability are critical.
