Frequently Asked Questions
\What is the ConnectX-6 adapter?
The Mellanox ConnectX-6 is a 200GbE/HDR InfiniBand VPI adapter with PCIe 4.0, hardware crypto offloads (IPsec/MACsec/TLS), and GPUDirect RDMA—designed for next-gen AI supercomputers and 200G storage fabrics.
Does ConnectX-6 support hardware encryption?
Yes. ConnectX-6 includes inline IPsec, MACsec, and TLS hardware crypto engines that offload encryption from the CPU at full line rate.
What PCIe does ConnectX-6 require?
PCIe 4.0 x16 for 200G line-rate. It also works in PCIe 3.0 x16 slots at reduced throughput (100G line-rate).
How does ConnectX-6 compare to ConnectX-7?
ConnectX-7 adds 400GbE, PCIe 5.0, and data-path acceleration for DPU offload. ConnectX-6 remains the best value for 200GbE/HDR deployments.
