BFKK MCX653105A-ECAT-SP ConnectX-6 HDR 100GbE network card

SKU CH-PFGX-TK6Y6 MPN MCX653105A-ECAT-SP

A 100GbE network adapter delivering 200Gb/s bandwidth, 215 million messages per second and sub-.6 microsecond latency over PCIe Gen 3.0 or 4.0

  • Up to 215 million messages per second for extreme throughput
  • Sub-0.6 µs latency accelerates compute clusters
  • Hardware XTS-AES encryption with FIPS support secures data
  • PCIe Gen 3.0 and 4.0 compatibility fits modern servers
  • Dual-speed 50G PAM4 and 25G NRZ SerDes enables flexible links

ConnectX-6 HDR 100GbE Adapter

The BFKK MCX653105A-ECAT-SP is a Mellanox ConnectX-6 VPI network interface card for Ethernet and InfiniBand fabrics. It delivers up to 100GbE and HDR100 EDR connectivity per port with a maximum aggregate bandwidth of 200Gb/s. The adapter achieves up to 215 million messages per second with latency under .6 microseconds. Hardware block-level XTS-AES encryption and FIPS support secure data in flight.

High-performance compute and storage clusters

This card suits builders scaling x86, Power, Arm, GPU or FPGA platforms that need high message rates, low CPU overhead and sub-nanosecond timing accuracy. It supports PCIe Gen 3.0 and Gen 4.0 slots, ODCC rack designs and RoHS compliance. Buyers who need wireless connectivity or consumer desktop speeds should look elsewhere. The feature set targets data-centre virtualization, NFV and storage offload workloads.

Dual 100GbE ports with PAM4 SerDes

The decisive specification is the dual-port 100GbE interface built on 50G PAM4 and 25G NRZ SerDes lanes. This physical-layer choice determines cable reach, transceiver compatibility and switch interoperability. Verify that your switch ports and cabling match these SerDes rates before purchase. The PCIe Gen 3.0 and 4.0 support sets the host-bus ceiling for the 200Gb/s throughput.

Questions about this item

How do I install the MCX653105A-ECAT-SP into a PCIe slot, and which generation setting do people often overlook?

Insert the card into a compatible PCIe slot; the adapter supports both PCIe Gen 3.0 and Gen 4.0, so verify the motherboard BIOS is set to the desired generation for full 100GbE throughput.

What maintenance or replacement will the ConnectX-6 card need over its service life?

The card has no user-serviceable parts; maintenance is limited to keeping the slot and QSFP cages free of dust and applying any firmware updates released by the manufacturer.

What is the first performance limit reached under sustained 100GbE loads?

Sustained traffic hits the 100GbE line-rate ceiling first; the hardware delivers up to 215 million messages per second with sub-0.6 usec latency before that bandwidth cap becomes the bottleneck.
