With support for multiple Ethernet speeds and advanced virtualization features, this NIC card represents an ideal solution for organizations seeking to enhance their network infrastructure.
Key Characteristics
- Dual QSFP28 ports supporting 100GbE and multiple lower speeds (1/10/25/40/50/56GbE)
- PCI Express 3.0 x16 host interface with backward compatibility
- Hardware offloads for overlay networks including NVGRE, VXLAN, and GENEVE
- RDMA over Converged Ethernet (RoCE) support for low-latency applications
- SR-IOV virtualization with up to 256 virtual functions per port
Advanced Technologies
This network adapter incorporates several cutting-edge technologies that enhance performance and efficiency:
- RoCE (RDMA over Converged Ethernet): Enables remote direct memory access over standard Ethernet networks
- Hardware Offload Engines: Dedicated processors for overlay network encapsulation/decapsulation
- T10-DIF Signature Handover: Hardware-assisted data integrity verification for storage applications
- SR-IOV Virtualization: Hardware-based I/O virtualization with guaranteed isolation
- Mellanox PeerDirect: Communication acceleration technology reducing data copies between devices
Operational Framework
The ConnectX-4 EN network card operates through a sophisticated architecture that offloads network processing tasks from the host CPU. The adapter features dedicated hardware engines for protocol processing, traffic management, and virtualization functions. For overlay networks, the NIC card performs encapsulation and decapsulation of NVGRE, VXLAN, and GENEVE packets at line rate, maintaining performance while enabling network scalability. The RoCE implementation leverages data center bridging capabilities to provide low-latency RDMA services over standard Ethernet infrastructure.
