Product overview

The NVIDIA ConnectX‑7 MCX75310AAS‑HEAT is a high‑performance RDMA network adapter that supports both InfiniBand and Ethernet protocols at speeds up to 400Gb/s. It integrates advanced in‑line security acceleration (IPsec, TLS, MACsec), PCIe Gen5 host interface, and a comprehensive set of offload engines for networking, storage, and HPC. Designed for the most demanding AI, scientific computing, and cloud data center environments, ConnectX‑7 delivers ultra‑low latency and exceptional throughput while reducing CPU overhead.

Multi‑protocol & speed

InfiniBand NDR 400Gb/s, HDR 200Gb/s, EDR 100Gb/s. Ethernet up to 400GbE, with support for NRZ (10/25G) and PAM4 (50/100G) interfaces. 1/2/4 port configurations.

In‑line security acceleration

Hardware offload for IPsec, TLS, and MACsec encryption/decryption (AES‑GCM 128/256‑bit). Secure boot, flash encryption, and device attestation for edge‑to‑core security.

ASAP² software‑defined networking

NVIDIA ASAP2 technology offloads overlay networks (VXLAN, GENEVE, NVGRE), connection tracking, flow mirroring, and packet rewriting. Delivers line‑rate performance with zero CPU penalty.

Precision timing & SyncE

IEEE 1588v2 PTP with 12 ns accuracy, G.8273.2 Class C, SyncE (G.8262.1), programmable PPS, and time‑triggered scheduling. Ideal for financial and 5G infrastructures.
