900-9X7AX-003NMC0 NVIDIA ConnectX-7 400G PCIe 5.0 x16 Ethernet Network Card

High-Performance PCIe 5.0 400GbE Data Center NIC featuring RoCE v2 RDMA with the 900-9X7AX-003NMC0

The 900-9X7AX-003NMC0 is an NVIDIA ConnectX-7 networking adapter engineered for modern AI and HPC fabrics where deterministic latency and sustained throughput are critical. Delivered as a PCIe 5.0 x16 add-in card, it provides a single-port 400GbE interface via QSFP112, aligning with leaf-spine topologies and GPU cluster interconnect requirements while preserving PCIe headroom for high-core-count CPU platforms.

Architecturally, the 900-9X7AX-003NMC0 combines RoCE v2 RDMA with hardware offloads to reduce host CPU cycles and stabilize tail latency under mixed traffic. NVMe-oF acceleration enables an Ethernet-based storage fabric with efficient queue processing, while TCP/IP offload and IPsec/TLS crypto offload support secure, high-bandwidth east-west flows without compromising application cores. IEEE 1588v2 PTP improves time alignment for distributed workloads, and PXE boot supports standardized provisioning across Linux, Windows Server, and VMware ESXi environments.

Why Choose the 900-9X7AX-003NMC0?

The 900-9X7AX-003NMC0 delivers a balanced density-to-performance profile by consolidating 400GbE connectivity and advanced offloads into a single PCIe Gen5 slot, enabling scalable cluster growth with predictable behavior. Its RDMA and storage-fabric capabilities support consistent service levels across GPU training nodes, compute partitions, and disaggregated NVMe resources, while the 50W power envelope simplifies integration planning in high-density server designs.

NVIDIA designs ConnectX adapters with a systems approach focused on end-to-end data path efficiency, reliable operation at scale, and alignment with contemporary data center standards for secure transport, time synchronization, and virtualization-ready networking.

Key Applications:

• AI/ML cluster leaf-spine networking
• HPC low-latency Ethernet with RDMA
• RoCE v2 GPU cluster interconnect
• NVMe-oF storage fabrics
• Virtualized multi-tenant network I/O
