MCX653105A-HDAL NVIDIA ConnectX-6 VPI 200G PCIe 4.0 x16 Ethernet Network Card

High-Performance Low-Profile VPI Networking Adapter featuring 200Gbps RDMA fabric with the MCX653105A-HDAL

The MCX653105A-HDAL is an NVIDIA ConnectX-6 VPI NIC designed to anchor 200GbE or HDR InfiniBand cluster fabrics where deterministic latency and high message rate are critical. Built as a low-profile, single-slot add-in card, it connects through PCIe 4.0 x16 to sustain line-rate throughput while minimizing host CPU overhead through RDMA acceleration and transport offloads.

Architecturally, the MCX653105A-HDAL aligns with modern AI/HPC nodes that require fast east-west traffic for GPU-to-GPU communication and storage backends. RoCE v2 enables low-latency Ethernet RDMA, while VPI flexibility supports InfiniBand deployments without changing the host platform. The single QSFP56 port scales up to 200Gbps and complements NVMe-oF offload for disaggregated storage, reducing jitter under parallel I/O. SR-IOV provides clean multi-tenant segmentation for virtualized clusters, and IPsec/TLS offload helps secure data-in-motion with minimal performance impact.

Why Choose the MCX653105A-HDAL?

The MCX653105A-HDAL delivers an efficient density-to-performance ratio by pairing PCIe Gen4 x16 host bandwidth with 200Gbps fabric capability in a low-profile form factor. It supports scalable deployment patterns—from compact 1U compute nodes to large-scale leaf-spine fabrics—while maintaining enterprise reliability through hardware offloads, precise timing, and consistent latency behavior under load.

NVIDIA engineers its data center networking to integrate cleanly with modern standards and operational tooling, prioritizing predictable performance, virtualization readiness, and secure transport capabilities suitable for always-on enterprise environments.

Key Applications:

• AI and HPC cluster interconnect
• RoCE v2 east-west networking
• InfiniBand HDR fabrics
• NVMe-oF disaggregated storage
• Virtualized and multi-tenant networking with SR-IOV
