Mellanox Technologies

Mellanox Technologies MCX653105A-ECAT 100Gb/s QSFP PCIe 4.0 x16 expansion card

SKU CH-ADS8-SJ96C MPN MCX653105A-ECAT

Provides 100Gb/s InfiniBand and Ethernet connectivity over a single QSFP port with PCIe 4.0 x16 bandwidth and sub-600ns latency

  • ConnectorsQSFP
  • InterfacePCI-Express
  • 100 Gb/s InfiniBand and Ethernet throughput via single QSFP port
  • Sub-600 ns latency accelerates HPC and data-centre workloads
  • 200 million messages per second for extreme message-rate performance
  • PCI Express 4.0 x16 interface delivers full bandwidth to the host
  • Supports 100, 50, 40, 25 and 10 Gb/s Ethernet plus HDR, HDR100, EDR, FDR, QDR, DDR and SDR InfiniBand speeds

ConnectX-6 VPI 100Gb/s adapter

The Mellanox ConnectX-6 VPI is a PCIe 4.0 x16 add-in card with a single QSFP port. It delivers 100Gb/s connectivity for both InfiniBand and Ethernet fabrics. The card targets data-centre and HPC clusters that need low-latency, high-throughput networking.

Capacity and headroom

The adapter supports InfiniBand speeds from SDR up to HDR100 and Ethernet rates of 10, 25, 40, 50 and 100Gb/s. It achieves sub-600ns latency and 200 million messages per second. Workloads that exceed 100Gb/s per port or require dual-port redundancy will need additional cards.

PCIe 4.0 x16 slot requirement

Installation requires a full-length PCI Express 4.0 x16 slot. Systems limited to PCIe 3.0 or smaller link widths will restrict available bandwidth. Verify slot availability and mechanical clearance before purchase.

Domande su questo articolo

Will this PCIe 4.0 x16 card run in my older PCIe 3.0 x16 slot?

Yes, the card is backward compatible and will operate at PCIe 3.0 x16 speeds, providing up to 100Gb/s throughput limited by the slot bandwidth.

How can I verify the ConnectX-6 is delivering 100Gb/s and sub-600ns latency after installation?

Check the link status LEDs on the QSFP port and use Mellanox firmware tools or standard OS utilities to confirm negotiated speed and latency counters.

Does the MCX653105A-ECAT include a QSFP transceiver or cable, or must I purchase them separately?

The adapter ships as a plug-in card only; compatible QSFP transceivers or direct-attach cables for 100Gb/s InfiniBand or Ethernet must be bought separately.
