Core Technologies & Standards
This smart network card is built on a foundation of
industry-leading technologies and complies with key standards:
- Networking: InfiniBand Trade Association 1.5, Ethernet IEEE 802.3 (10G to
400GbE), RoCE v2, VXLAN/GENEVE overlay offload
- Interconnect: PCI Express 5.0 x16 host interface, supporting the latest server
platforms
- Security: Inline hardware acceleration for IPsec, TLS 1.3, and MACsec
(AES-GCM 128/256)
- Virtualization: SR-IOV (Single Root I/O Virtualization) for efficient virtual
machine connectivity
- Management: NC-SI, Redfish, PLDM (Platform Level Data Model) for firmware and
device management
Working Principle
The ConnectX-7 NIC card functions as an intelligent data plane
processor installed in a server's PCIe slot. It offloads network,
storage, and security processing tasks from the host CPU to its
dedicated hardware engines. For data transfer, it utilizes Remote
Direct Memory Access (RDMA) to enable direct, kernel-bypass
communication between application memory spaces across the network,
drastically reducing latency and CPU utilization. Its programmable
pipeline and parsing engine handle complex packet processing,
encapsulation (like VXLAN), and security protocols at line rate,
ensuring maximum performance for virtualized and bare-metal
deployments.
Application Scenarios
- Artificial Intelligence & Machine Learning: Accelerates distributed training by providing high-throughput,
low-latency connectivity between GPUs and compute nodes
- High-Performance Computing (HPC): Essential for scientific simulations, climate modeling, and
financial analytics clusters requiring massive parallel
communication
- Hyperscale Cloud Data Centers: Enables high-density virtualized environments, software-defined
networking (SDN), and efficient storage disaggregation
- High-Frequency Trading & Real-Time Analytics: Delivers the microsecond latency and precise time synchronization
needed for time-sensitive decision making
- Enterprise Storage & Data Backup: Optimizes performance for NVMe-oF and GPUDirect Storage,
facilitating fast access to centralized storage pools

Frequently Asked Questions
Q: Is the MCX75310AAS-NEAT compatible with my existing 100GbE
switches?
A: Yes. This network card is backward compatible and will
auto-negotiate down to 10GbE. For 400GbE, ensure your switch
supports the same standard (e.g., 400GBASE-SR8, DR4)
Q: What is the difference between InfiniBand and Ethernet mode on
this NIC card?
A: The adapter can be configured via firmware for either InfiniBand
or Ethernet operation. InfiniBand mode offers lower latency and
advanced features like SHARP for HPC. Ethernet mode provides broad
compatibility with standard data center networks and supports RoCE
for RDMA
Q: Does this adapter support VMware virtualization?
A: Yes, it fully supports VMware ESXi with SR-IOV, allowing direct
assignment of virtual functions to VMs for near-native performance
Q: Can I use this card for GPUDirect Storage?
A: Absolutely. The ConnectX-7 has dedicated hardware offloads for
GPUDirect Storage, enabling GPUs to directly access storage over
the network with minimal CPU involvement
Important Precautions
- Compatibility: Verify server has a PCIe Gen4 or Gen5 x16 slot for full
performance. BIOS settings may need adjustment for PCIe bifurcation
or SR-IOV
- Thermal Management: Ensure adequate airflow within the server chassis, as
high-performance network cards generate significant heat
- Driver & Firmware: Always use the latest stable drivers and firmware from the
official NVIDIA support website for optimal performance and
security
- Cabling: Use qualified optical or DAC/AEC cables rated for the target speed
(e.g., NDR InfiniBand or 400GbE)
- Security Configuration: When utilizing hardware encryption (IPsec/TLS), proper key
management and security policy configuration are essential
