Mellanox Technologies CX354A ConnectX-3 VPI 40GbE dual-port QSFP+ network card

SKU CH-178S-9S8TM MPN CX354A

A dual-port 40 GbE QSFP+ network card for high-speed server connectivity

  • Dual-port design doubles 40GbE bandwidth potential
  • QSFP+ interfaces support high-density fibre or copper links
  • ConnectX-3 VPI engine handles Ethernet and InfiniBand traffic
  • Low-profile bracket fits 1U and blade server chassis
  • New condition ensures full manufacturer specification compliance

Dual-Port 40GbE Adapter

The Mellanox CX354A ConnectX-3 VPI card adds two QSFP+ ports for 40GbE networking over PCIe. It is built for servers and workstations that need high-throughput, low-latency links in storage or compute clusters. The dual-port design supports link aggregation or separate fabrics. Condition is new.

Suits Multi-Port 40GbE Deployments

This adapter fits environments that run dual 40GbE connections for redundancy or bandwidth scaling. It is not for buyers who need only a single 40GbE link. It is not for systems that require port speeds beyond 40GbE. It is not for slots that lack the required PCIe interface.

Two QSFP+ Ports at 40GbE

The deciding specification is the dual QSFP+ interface rated at 40GbE maximum data rate. Verify that your chassis, cables and switch ports match this exact port count and speed before purchase.

Questions about this item

Does the CX354A card ship with any QSFP+ transceivers or cables, or must they be purchased separately?

The card provides two QSFP+ ports; transceivers and cables are not included and must be sourced separately to match your link type and distance.

Which part number should I select if I need the low-profile bracket version of this dual-port 40GbE adapter?

Choose MCX354A-FCBT/LP for the low-profile bracket; the base MCX354A-FCBT ships with a full-height bracket.

What throughput can I expect from each port when the card is installed in a PCIe 3.0 x8 slot?

Each port supports up to 40GbE line rate; a PCIe 3.0 x8 host interface provides sufficient bandwidth for both ports simultaneously.
