About the NVIDIA MCX653105A-HDAT ConnectX-6 Network Adapter
The NVIDIA MCX653105A-HDAT ConnectX-6 Network Adapter delivers single-port 100Gb/s performance in a low-profile PCIe form factor, making it the gateway to next-generation datacenter connectivity. This adapter supports InfiniBand HDR100, 100GbE, and backward-compatible protocols down to 10GbE, all via a single QSFP56 port. With PCIe 4.0 x16 host interface connectivity, the MCX653105A-HDAT integrates into modern server architectures with minimal latency and maximum throughput. The included full-height bracket ensures flexible deployment across diverse chassis designs.
Network engineers and datacenter infrastructure teams choose this NVIDIA adapter to unlock high-performance computing capabilities without overprovisioning. The ConnectX-6 series excels in scenarios demanding RDMA transport across InfiniBand, RoCEv2, and RoCEv1 protocols, while NVIDIA SHARP v2 in-network computing and GPUDirect RDMA support accelerate AI and machine learning workloads. Up to 1,024 SR-IOV virtual functions enable dense multi-tenant deployments, and comprehensive offload engines—including VXLAN, NVGRE, and GENEVE stateless offloads plus TCP/UDP checksum and LSO/LRO—reduce CPU overhead. Operating across 0°C to 55°C with just 25W maximum power consumption, this adapter delivers efficiency alongside performance. Hardware-enforced isolation and AES encryption (256-bit and 128-bit in-line) meet stringent enterprise security requirements. Driver support spans MLNX_OFED for Linux, WinOF-2 for Windows, and major Linux inbox drivers, alongside virtualization platforms including VMware vSphere, KVM, and Hyper-V.
