About the Mellanox MCX75310AAS-HEAT ConnectX-7 VPI Adapter, 1x OSFP, 400Gb/s InfiniBand / 400GbE
The Mellanox MCX75310AAS-HEAT ConnectX-7 VPI adapter is engineered for high-performance data centers requiring unified 400Gb/s InfiniBand NDR 400Gb/s and 400GbE Ethernet connectivity in a single, compact PCIe interface. Built on Mellanox's proven ConnectX-7 VPI platform, this single-port OSFP adapter delivers line-rate performance with PCIe 5.0 x16 host bus integration in a low-profile, half-height form factor suitable for dense server deployments. The MCX75310AAS-HEAT variant features passive cooling optimized for chassis airflow, making it ideal for environments where thermal management and reliability are critical.
Designed for network engineers and AI infrastructure teams building next-generation compute clusters, this adapter supports advanced offload capabilities including GPUDirect RDMA, DPDK, ASAP², and in-network computing acceleration for MPI_Allreduce operations. Mellanox integrated RoCEv2 and InfiniBand RDMA support with multi-tenancy isolation via SR-IOV, plus inline AES-256 data-path encryption at line rate for secure data transmission. The adapter operates across Linux distributions (RHEL, SLES, Ubuntu) and VMware ESXi environments, managed through OpenSM, UFM, and the MLNX_OFED toolset. Operating temperature range is 0°C to 55°C, ensuring compatibility with standard enterprise data center conditions.
Enterprise Deployment Scenarios
- High-performance computing (HPC) clusters requiring 400Gb/s low-latency InfiniBand connectivity with RDMA acceleration
