MCX653106A-HDAL Mellanox ConnectX-6 VPI 200G PCIe 4.0 x16 Ethernet Network Card

High-Performance Low-Profile 200Gb VPI NIC featuring PCIe 4.0 RDMA offloads with the MCX653106A-HDAL

The MCX653106A-HDAL is a low-profile Mellanox/NVIDIA ConnectX-6 VPI network adapter designed for latency-sensitive Ethernet and InfiniBand fabrics in modern HPC and AI clusters. By combining a 200Gb QSFP56 port with dual-fabric capability, the MCX653106A-HDAL supports both InfiniBand and RoCE-based Ethernet designs, allowing architects to standardize a single NIC SKU across mixed interconnect requirements.

Using a PCIe 4.0 x16 host interface, the MCX653106A-HDAL sustains high packet and message rates while keeping CPU overhead predictable through RDMA and protocol offloads. For storage disaggregation, NVMe-oF acceleration enables efficient NVMe data paths over the fabric, while integrated IPsec/TLS crypto offload helps protect east-west traffic without consuming host cycles. SR-IOV provides scalable multi-tenant I/O virtualization for container and VM deployments, and IEEE 1588 PTP timing support improves determinism for distributed workloads and telemetry correlation.

Why Choose the MCX653106A-HDAL?

The MCX653106A-HDAL delivers a strong density-to-performance ratio by concentrating 200Gb connectivity and advanced offloads into a low-profile PCIe 4.0 adapter suited for 1U/2U servers. It enables consistent cluster scaling through RDMA-capable fabrics, reduces application tail latency for MPI and distributed training, and supports reliable provisioning with PXE and UEFI PXE for repeatable fleet deployment.

Mellanox engineering emphasizes predictable latency, hardened firmware, and interoperability with enterprise data centre standards, aligning the platform with Linux and Microsoft Windows environments and common automation toolchains.
