Overview
Product overview
The NVIDIA ConnectX-6 MCX653106A-HDAT is a dual-port 200Gb/s InfiniBand and Ethernet smart adapter, designed as a cornerstone of the NVIDIA Quantum InfiniBand platform. It integrates advanced features like Remote Direct Memory Access (RDMA), NVMe over Fabrics (NVMe-oF) offloads, and block-level encryption to drastically reduce CPU overhead. By moving computation into the network fabric, this adapter enhances scalability and efficiency for high-performance computing, machine learning workloads, and hyperscale cloud infrastructures.
Key features
- Ultra-High Throughput: 200Gb/s connectivity per port with a maximum aggregate bandwidth of 200Gb/s.
- In-Network Computing: Hardware offloads for collective operations, MPI tag matching, and rendezvous protocol.
- Block-Level Encryption: XTS-AES 256/512-bit hardware encryption for FIPS-compliant data security.
- PCIe 4.0 Support: 16 GT/s link rate with full backward compatibility to PCIe 3.0/2.0/1.1.
- Message Rate: Up to 215 million messages per second for extreme small-packet performance.
- Storage Offloads: NVMe-oF target and initiator offloads, T10-DIF, and support for SRP, iSER, NFS RDMA.
- Virtualization: SR-IOV with up to 1K virtual functions and ASAP2 for OVS offload.
- ConnectX-6 integrates NVIDIA’s unique In-Network Computing engines, offloading collective communication operations (like MPI all-reduce) from the CPU to the network fabric. This drastically reduces latency and frees CPU cycles for application processing. Combined with RDMA and advanced memory mapping (UMR), the adapter enables GPU Direct RDMA and peer-to-peer GPU communication across the network, accelerating AI training clusters and complex simulations.
Typical applications
- High-Performance Computing (HPC): Large-scale clusters running weather simulation, computational fluid dynamics, and molecular dynamics.
- AI & Machine Learning: Distributed training of deep neural networks requiring high throughput and low latency.
- Enterprise Data Centers: NVMe-oF storage targets, database acceleration, and virtualized infrastructure.
- Hyperscale Cloud: Multi-tenant environments requiring hardware-based isolation and QoS.
- Liquid-Cooled Platforms: Compatible with Intel Server System D50TNP cold plate designs for high-density deployments.
