- PCIe 3.0 x16 interface delivers 16 lanes bandwidth
- NVMe over Fabric offload boosts storage performance
ConnectX-5 VPI adapter for high-performance networks
The Mellanox ConnectX-5 VPI adapter card installs in a PCI Express 3.0 x16 slot and provides two 100Gb/s optical ports. It targets data centres that run machine learning, analytics and HPC workloads requiring RDMA and hardware offloads.
Dual 100Gb/s optical ports with sub-600 ns latency
The card delivers two ports of 100Gb/s InfiniBand and Ethernet connectivity. Sub-600 ns latency and very high message rates make it the decisive specification for latency-sensitive clusters and storage fabrics.
Low-latency operation with NVMe offload support
Intelligent offload engines handle MPI, SHMEM and NVMe over Fabric traffic in hardware, reducing host CPU load and power draw during sustained high-throughput transfers. The design keeps thermals and noise within typical rack expectations.

Questions about this item
What does 100Gb/s bandwidth mean once the card is installed in a server?
The adapter delivers up to 100Gb/s per port for InfiniBand or Ethernet traffic, enabling sub-600 ns latency and very high message rates for HPC, machine learning and storage workloads.
How does the PCI Express 3.0 x16 interface limit real-world throughput?
The PCIe 3.0 x16 slot provides up to 16 GT/s per lane, giving the card enough host bandwidth to sustain dual-port 100Gb/s line rate without bottlenecking the data path.
What physical slot and cabling does this adapter require to fit and operate?
It occupies a standard PCIe 3.0 x16 slot and uses optical fiber transceivers for both ports, so compatible fibre patch cables and free full-height bracket space are needed.
