Mellanox Technologies CX653105A 200GbE QSFP56 Adapter Card

SKU CH-TPF7-3GM2Q MPN CX653105A

A single-port 200GbE QSFP56 adapter card using the ConnectX-6 VPI controller

  • 200 GbE throughput for high-bandwidth workloads
  • Single QSFP56 port simplifies cabling
  • ConnectX-6 VPI architecture handles demanding traffic
  • PCI Express compatibility fits standard servers
  • Model CX653105A identifies the exact part

Single-port 200GbE QSFP56 adapter

This Mellanox ConnectX-6 VPI card provides one 200GbE QSFP56 port for high-throughput wired networking. It installs in a compatible PCI Express slot and targets data-centre and high-performance computing environments where 200 gigabit per second links are required.

Suited for 200GbE single-port deployments

Buyers needing a single 200GbE QSFP56 connection for cluster interconnects, storage fabrics or dense server deployments will find this adapter appropriate. It is not for systems lacking a compatible PCI Express slot, for deployments requiring multiple ports on one bracket, or for networks operating at lower speeds without 200GbE infrastructure.

200GbE QSFP56 single-port interface

The decisive specification is the single 200GbE QSFP56 port, which dictates cable, transceiver and switch compatibility. Verify that the host platform supplies a suitable PCI Express slot and that the surrounding network fabric supports 200GbE operation before purchase.

Questions about this item

Does the MCX653105A-HDAT card fit a standard PCI Express slot?

Yes, the ConnectX-6 VPI adapter uses a PCI Express interface, so it installs in any compatible PCIe slot on the motherboard.

What is the common mistake when inserting the QSFP56 transceiver into the 200GbE port?

The transceiver must be pushed until the latch clicks; a partial insert leaves the link down even though the module appears seated.

When should the QSFP56 module or cable be replaced on this 1-port adapter?

Replace the module or direct-attach cable if link errors rise, the port fails to negotiate 200GbE speed, or the latch mechanism no longer holds securely.
