Description

The NVIDIA ConnectX-6 VPI adapter card delivers 200Gb/s InfiniBand HDR and Ethernet connectivity in a single-port QSFP56 form factor with PCIe 4.0 x16 host interface. Engineered for high-performance computing, AI/ML workloads, and data center applications, this adapter provides sub-600ns latency, 215 million messages per second, and supports advanced features including RDMA, RoCEv2, GPUDirect, and PTP hardware timestamping. The Virtual Protocol Interconnect technology enables flexible protocol switching between InfiniBand and Ethernet on a single adapter.

FAQs

Q: What is VPI and how does it benefit my deployment?
A: Virtual Protocol Interconnect (VPI) allows the ConnectX-6 adapter to dynamically switch between InfiniBand and Ethernet protocols on the same port. This provides deployment flexibility, enabling you to run either HDR InfiniBand for HPC clusters or 200GbE for data center networking without changing hardware.

Q: Is this adapter compatible with NVIDIA GPUDirect technology?
A: Yes, the ConnectX-6 fully supports NVIDIA GPUDirect RDMA and GPUDirect Storage, enabling direct memory access between GPUs and the network adapter. This bypasses CPU overhead, dramatically accelerating AI/ML training, HPC simulations, and GPU-accelerated workloads.

Q: What RoCE version does this adapter support?
A: The adapter supports RoCEv2 (RDMA over Converged Ethernet version 2), providing lossless RDMA capabilities over standard Ethernet networks. This enables low-latency, high-throughput data transfers for storage, virtualization, and cloud applications without requiring InfiniBand infrastructure.

Q: Can I use this adapter for NVMe over Fabrics storage arrays?
A: Absolutely. The ConnectX-6 provides hardware-accelerated NVMe over Fabrics support, functioning as both initiator and target. This enables ultra-low latency access to NVMe SSDs over the network, ideal for disaggregated storage architectures and all-flash arrays.

Q: What is the typical power consumption of this adapter?
A: Power consumption varies based on traffic load and port speed configuration. Ensure your server's PCIe slot can supply adequate power per the specifications in the NVIDIA ConnectX-6 documentation. The adapter is designed for standard enterprise server power envelopes with PCIe 4.0 x16 slots.
