The NVIDIA MCX755106AS‑HEAT (PN:900‑9X7AH‑0078‑DTZ) is a ConnectX‑7 VPI dual‑protocol smart network adapter, designed for AI training clusters, HPC, NVMe‑oF storage and hyperscale cloud data‑center deployments. It delivers dual‑port 200Gb/s connectivity over QSFP112 ports, supporting both NDR200 InfiniBand and 200GbE Ethernet, each port can independently switch between InfiniBand and Ethernet modes.
Host interface is PCIe 5.0 x16 running at 32 GT/s, backward compatible with PCIe 4.0 / PCIe 3.0. It supports Socket‑Direct via optional auxiliary PCIe extension card for advanced server topologies. Form‑factor is HHHL (Half‑Height Half‑Length), comes with full‑height bracket, low‑profile bracket optional for flexible 1U/2U rack server installation. This variant features Secure Boot Enabled, Crypto Functions Disabled.
Hardware‑accelerated RDMA, RoCE v2, GPUDirect RDMA and GPUDirect Storage offload CPU overhead, achieve ultra‑low latency and optimize NCCL collective communication for large‑scale GPU workloads. Integrated offloads include SR‑IOV virtualization, ODP on‑demand paging, NVIDIA SHARP in‑network aggregation, adaptive routing, congestion control and IEEE 1588 PTP precision time synchronization. Supports NVMe‑oF, NVMe‑over‑TCP for high‑performance storage systems.
Supported operating systems include Linux, Windows and VMware ESXi, managed via NVIDIA AmpCon platform for fabric‑wide provisioning and monitoring. Typical power consumption is 24.9W, operating temperature range 0°C‑55°C. Ideal for GPU‑accelerated AI nodes, high‑performance computing, distributed storage and virtualized data‑center environments.
