MCX683105AN-HDAT
High-Performance InfiniBand Host Adapter enabling 200Gb/s RDMA fabrics with the MCX683105AN-HDAT
The MCX683105AN-HDAT is a ConnectX-6 DE InfiniBand NIC engineered for low-latency, high-throughput cluster interconnects where GPU and CPU nodes must exchange data deterministically. By combining a single-port 200Gb/s QSFP56 interface with RDMA acceleration, it reduces CPU overhead and enables predictable message passing for MPI and collective operations in scale-out environments.
On the host side, the MCX683105AN-HDAT uses a PCIe 4.0 x16 interface to sustain line-rate traffic while maintaining headroom for concurrent storage and east-west flows. The adapter’s offload capabilities align with modern memory-centric architectures by keeping data movement close to the fabric, while SR-IOV provides efficient virtual function provisioning for multi-tenant nodes and VMware, Linux, or Windows deployments. For disaggregated storage, NVMe-oF support allows the MCX683105AN-HDAT to act as a high-bandwidth back-end path, improving queue depth utilization and reducing latency variance compared to CPU-bound transports.
Why Choose the MCX683105AN-HDAT?
The MCX683105AN-HDAT delivers a strong density-to-performance profile in a FHHL PCIe form factor, enabling 200Gb/s InfiniBand connectivity per server without compromising expansion planning. It is designed for enterprise reliability and operational scale, supporting precise timing via IEEE 1588 PTP, boot workflows through PXE and UEFI PXE, and consistent performance under mixed RDMA, storage, and virtualization traffic.
Mellanox engineering focuses on lossless fabric behavior, robust driver maturity, and standards-aligned interoperability across data center operating systems and hypervisors. This approach supports repeatable deployments in HPC and AI clusters that demand deterministic transport, predictable lifecycle management, and integration with modern rack server platforms.
Key Applications:
- HPC InfiniBand fabrics and MPI clusters
- AI/ML distributed training and GPU interconnect
- RDMA-enabled microservices and virtualization
- NVMe-oF disaggregated storage back-end
- Low-latency data analytics pipelines
