New Original Nvidia MCX456A-Ecat Connectx-4 Infiniband/Ethernet Adapter Card

Mellanox ConnectX-4 VPI Adapter Card MCX456A-ECAT

The Mellanox ConnectX-4 VPI adapter card represents a significant leap in high-performance networking technology. This advanced network card delivers exceptional 100Gb/s bandwidth, ultra-low latency, and robust hardware offload capabilities. Designed for data-intensive environments, the ConnectX-6 predecessor model sets a high standard, but the ConnectX-4 VPI stands as a powerful and cost-effective solution for enterprises requiring top-tier performance without the premium price tag.

Key Specifications:

• Dual-port 100Gb/s InfiniBand EDR and Ethernet connectivity
• PCIe 3.0 x16 host interface with low-profile form factor
• Hardware offload for RDMA, RoCE, NVGRE, and VXLAN
• SR-IOV virtualization with up to 256 virtual functions
• T10-DIF signature handover and erasure coding support

Technical Characteristics

• Dual-port 100Gb/s InfiniBand EDR and 100GbE connectivity
• Support for 1/10/25/40/50/56/100GbE speeds
• 150 million messages per second throughput
• Hardware-based I/O virtualization (SR-IOV)
• RDMA over Converged Ethernet (RoCE) v1 and v2
• Erasure Coding (Reed-Solomon) offload
• NVGRE and VXLAN encapsulation/decapsulation
• Energy Efficient Ethernet (EEE) support
• RoHS-R6 compliant

Core Technologies

The ConnectX-4 nic card leverages cutting-edge technologies including IBTA RDMA, RoCE, and hardware offloads for overlay networks (NVGRE/VXLAN). It complies with InfiniBand Trade Association (IBTA) 1.3 and IEEE Ethernet standards (802.3bj, 802.3bm, 802.3ba). The adapter's Virtual Protocol Interconnect (VPI) technology enables flexible deployment across both InfiniBand and Ethernet networks with a consolidated software stack.

MCX456A-Ecat Operational Mechanism

The ConnectX-4 network card operates through specialized hardware engines that offload network, storage, and virtualization processing from the host CPU. It utilizes Mellanox's PeerDirect technology for efficient RDMA access, eliminating unnecessary data copies between components on the PCIe bus. For overlay networks, dedicated hardware engines handle encapsulation and decapsulation of NVGRE and VXLAN headers, maintaining performance while reducing CPU overhead.

MCX456A-Ecat Application Scenarios

• High-Performance Computing (HPC) and AI clusters
• Cloud infrastructure and Web 2.0 data centers
• Big Data analytics and machine learning platforms
• Virtualized storage and software-defined infrastructure
• Financial services and real-time trading systems
• High-frequency database and transaction processing
