Product Description
NVIDIA ConnectX-5 MCX555A-Ecat InfiniBand Network Adapter Card
The NVIDIA ConnectX-5 InfiniBand network card delivers breakthrough performance with dual-port 100Gb/s InfiniBand and Ethernet connectivity. Designed for high-performance computing, cloud, and storage environments, this intelligent adapter features advanced offloads, low latency, and high message rates—making it an ideal choice for data-intensive applications.
MCX555A-Ecat Key Selling Points
- Dual-port 100Gb/s InfiniBand and Ethernet support
- Hardware offload for NVMe over Fabrics, MPI, and RDMA
- PCIe Gen4 and Gen3 compatibility with embedded switch
- Support for Multi-Host and Socket Direct configurations
- RoHS compliant and energy-efficient design
MCX555A-Ecat Characteristics
- High throughput: Up to 100Gb/s per port
- Low latency and CPU utilization
- Hardware-based congestion control
- Support for jumbo frames (up to 9.6KB)
- Enhanced virtualization with SR-IOV and ASAP²
MCX555A-Ecat Technology
The ConnectX-5 nic card leverages cutting-edge technologies including RDMA, RoCE, NVMe-oF offload, and adaptive routing. It supports a wide range of standards such as IEEE 802.3, InfiniBand 1.3, and PCIe Gen4. Advanced features include dynamic connected transport (DCT), hardware-based tag matching, and burst buffer offload for checkpointing.
Working Principle
The network card operates by offloading network processing tasks from the CPU directly to the hardware. It uses RDMA to enable direct memory access between systems, reducing latency and improving throughput. The embedded PCIe switch allows efficient I/O consolidation, while hardware accelerators handle encapsulation, decapsulation, and protocol processing.
Applications
- High-Performance Computing (HPC) clusters
- Cloud and hyperscale data centers
- NVMe over Fabrics storage systems
- Artificial Intelligence and Machine Learning platforms
- Virtualized and software-defined infrastructures
