NVIDIA ConnectX-6 MCX654105A-HCAT 200G HDR VPI Adapter

NVIDIA ConnectX-6 MCX654105A-HCAT 200G HDR VPI Adapter

Brand:

NVIDIA

NVIDIA Mellanox MCX654105A-HCAT is a ConnectX-6 VPI network adapter designed for 200Gb/s HDR InfiniBand and 200GbE connectivity. It features a single QSFP56 port and a Socket Direct design using two PCIe Gen3 x16 connections. Its VPI capability lets buyers deploy the same adapter for InfiniBand or Ethernet networking, making it suitable for HPC, AI, GPU computing, and high-bandwidth data-center infrastructure.

OVERVIEW

The MCX654105A-HCAT is a ConnectX-6 VPI adapter for 200Gb/s HDR InfiniBand and 200GbE, with one QSFP56 port and Socket Direct dual PCIe Gen3 x16 connectivity. Compatibility: requires two PCIe x16 slots plus the supplied auxiliary connection/harness arrangement. Model comparison: unlike single-slot ConnectX-6 VPI models, this design uses Socket Direct to deliver 200G connectivity on PCIe Gen3 servers. Verify server slot, airflow, firmware and cabling requirements before purchase.

USE CASES

HPC clusters: Connect compute nodes to high-speed InfiniBand fabrics for demanding parallel workloads.
AI and GPU clusters: Provide high-bandwidth node connectivity for distributed AI and GPU computing environments.
Data-center Ethernet: Use 200GbE connectivity for high-throughput server and infrastructure networking.
Scientific computing: Support data-intensive research environments requiring high-speed interconnects.
Machine learning infrastructure: Connect accelerated computing systems where network bandwidth is critical to cluster performance.
Storage networking: Support high-bandwidth Ethernet or InfiniBand connectivity in suitable storage architectures.
Cloud infrastructure: Deploy in high-performance server environments requiring flexible VPI networking.
Large-scale compute clusters: Build high-speed interconnects between servers using HDR InfiniBand.
Network modernization: Upgrade compatible PCIe Gen3 server platforms to 200Gb/s-class connectivity without requiring a PCIe Gen4 host interface.

KEY FEATURES

200Gb/s HDR InfiniBand: Delivers high-speed interconnect capability for HPC and AI clusters.
200GbE Support: Provides high-bandwidth Ethernet networking for modern data-center environments.
VPI Architecture: Allows the adapter to operate with InfiniBand or Ethernet networking, providing deployment flexibility.
Single QSFP56 Port: Provides one high-speed physical network interface.
Socket Direct Design: Uses two PCIe x16 connections to provide the required host-side bandwidth for 200Gb/s operation.
PCIe Gen3 x16: Enables 200Gb/s-class connectivity on compatible PCIe Gen3 server platforms.
HDR Support: Supports HDR InfiniBand at 200Gb/s for high-performance cluster fabrics.
Broad Ethernet Rates: Supports Ethernet data rates including 10/25/40/50/100/200Gb/s, subject to the applicable configuration and link technology.
QSFP56 Interface: Supports copper and optical connectivity options compatible with the specified interface.
Tall Bracket: Suits compatible full-height server expansion-slot installations.
