Mellanox Technologies MCX653106A-HDAL 200Gbps Dual-port QSFP56 PCIe 4.0 x16 laptop networking

SKU CH-6EX8-V02PF MPN MCX653106A-HDAL

A dual-port QSFP56 network card delivering 200 Gbps over PCI Express 4.0 x16 for wired Ethernet and InfiniBand connectivity

  • Dual 200 Gbps ports for high-throughput workloads
  • PCI Express 4.0 x16 interface delivers full bus bandwidth
  • QSFP56 connectors support Ethernet and InfiniBand protocols
  • Multi-rate link capability from 10 to 200 Gbps
  • TCP/IP, UDP/IP and iSCSI offload reduce host CPU load

Dual-port 200 Gbps QSFP56 network card

The Mellanox MCX653106A-HDAL is a dual-port network card delivering 200 Gbps per port over QSFP56 connectors. It supports Ethernet and InfiniBand protocols at speeds from 10 Gbps up to 200 Gbps. The card targets high-performance computing clusters and storage fabrics that require low-latency wired connectivity.

PCI Express 4.0 x16 slot and QSFP56 cabling

Verify that the host system provides a PCI Express 4.0 x16 slot with sufficient lane allocation and bracket clearance. The card uses two QSFP56 ports, so matching transceivers or direct-attach cables rated for 200 Gbps must be sourced separately. Confirm the operating system includes drivers for Mellanox ConnectX-6 Dx controllers.

No transceivers or cables included

The package contains only the network card itself; QSFP56 transceivers, active optical cables or direct-attach copper cables are not supplied. Buyers must procure compatible 200 Gbps optics or DACs to activate either port. Without these accessories the card cannot establish a link.

  • QSFP56 connectors support Ethernet and InfiniBand protocols
  • Multi-rate link capability from 10 to 200 Gbps
  • TCP/IP, UDP/IP and iSCSI offload reduce host CPU load

Questions about this item

Does the MCX653106A-HDAL come with QSFP56 transceivers and cables, or must they be purchased separately?

The card provides two QSFP56 cages for 200 Gbps Ethernet or InfiniBand links; transceivers and cables are not included and must be sourced separately.

Should I choose this dual-port 200 Gbps model or a single-port 100 Gbps card for my workload?

Select the MCX653106A-HDAL when you need two independent 200 Gbps ports for redundancy or aggregated throughput; a single-port 100 Gbps card only delivers one 100 Gbps link.

What does the 200 Gbps rating mean once the card is installed in a PCIe 4.0 x16 slot?

Each port can run at 200 Gbps Ethernet or InfiniBand, and the PCIe 4.0 x16 interface supplies enough lane bandwidth to sustain both ports simultaneously.
