product details

NVIDIA MCX653105A-HDAT ConnectX-6 200G VPI Network Adapter

The NVIDIA MCX653105A-HDAT ConnectX-6 VPI adapter is listed as a single-port QSFP56 card for 200GbE and HDR InfiniBand environments. Its PCIe 4.0 x16 host connection and tall-bracket format make it a candidate for high-throughput server networking where the switch, cable or transceiver, driver, and firmware are selected as one compatible system. VPI deployments require deliberate port-mode planning because InfiniBand and Ethernet configuration should match the fabric design.

Listed configuration

  • Model: NVIDIA MCX653105A-HDAT / ConnectX-6 VPI
  • Port configuration: single QSFP56 port
  • Network use: 200GbE Ethernet or HDR InfiniBand, subject to configuration
  • Host interface: PCIe 4.0 x16
  • Bracket: tall / full-height style

Integration checklist

Confirm the target server has a suitable PCIe 4.0 x16 slot, adequate airflow, and the required bracket height. Match the port to a validated QSFP56 cable or optical module, the selected switch port, and the intended Ethernet or InfiniBand mode. Before installation, confirm driver, firmware, operating-system, and cluster-stack requirements with the platform owner. A connector match by itself does not prove end-to-end interoperability.

Request a compatibility review

Provide the server model, switch model and port speed, cable or optic preference, required protocol, rack quantity, and destination. Topstar can quote the adapter together with matched interconnect components and help avoid a mixed-mode or physical-fit mismatch.
