Universal MCX455A-ECAT ConnectX-4 VPI Network Adapter PCIe 3.0 x16 100 Gigabit Ethernet

SKU CH-FABX-JJPS5

ConnectX-4 VPI adapter delivers 100 Gigabit Ethernet over PCIe 3.0 x16 for high-bandwidth, low-latency workloads

  • 100 Gigabit Ethernet bandwidth for high-throughput workloads
  • PCI Express 3.0 x16 interface delivers 16 lanes of connectivity
  • ConnectX-4 VPI silicon optimises low-latency message rates
  • Smart interconnect supports x86, Power, ARM and GPU platforms
  • Efficient I/O consolidation reduces data-centre cost and complexity

Universal ConnectX-4 VPI Adapter

This Mellanox ConnectX-4 VPI network adapter delivers 100 Gigabit Ethernet connectivity through a PCI Express 3.0 x16 interface. It is built for high-bandwidth, low-latency workloads in cluster, storage and virtualised overlay environments. The card suits data-centre operators who need efficient I/O consolidation on x86, Power, ARM or GPU-based platforms.

Suits 100 GbE infrastructure upgrades

Teams deploying 100 Gigabit Ethernet links in existing PCIe 3.0 x16 slots will find the MCX455A-ECAT a direct fit. Buyers whose switches, cabling or server backplanes operate at lower speeds and have no upgrade path to 100 GbE should evaluate slower adapters that match their current fabric.

PCIe 3.0 x16 lane requirement

The adapter requires a full x16 electrical connection running at PCI Express 3.0 to achieve its rated 100 GbE throughput. Servers or risers that provide fewer than 16 lanes or an older PCIe generation will limit bandwidth and may prevent the card from operating as specified.

Questions about this item

How much heat does the ConnectX-4 MCX455A-ECAT generate when running at 100 GbE all day?

The adapter is rated for up to 16 W typical power draw; plan chassis airflow to dissipate that heat continuously.

What slot and bus does the MCX455A-ECAT require to operate at 100 GbE?

It needs a PCI Express 3.0 x16 slot; the card will not reach full bandwidth in a smaller link.

Will the MCX455A-ECAT work in a server that only has PCIe 2.0 slots?

The card fits physically but negotiates down to PCIe 2.0 speeds, limiting throughput well below the 100 GbE rating.
