Core Technologies
This advanced network card incorporates multiple cutting-edge technologies including PCI Express 4.0 interface, hardware-accelerated RoCE for low-latency RDMA operations, and ASAP² (Accelerated Switch and Packet Processing) for offloading software-defined networking functions. The NIC card supports advanced security through inline IPsec encryption with AES-XTS 256/512-bit keys and provides hardware-enforced security with secure boot capabilities. The ConnectX-6 architecture also features sophisticated quality of service (QoS) mechanisms and overlay network processing capabilities.
Operational Methodology
The ConnectX-6 Lx SmartNIC operates by offloading network processing tasks from the host CPU to specialized hardware engines. Through its programmable pipeline, the network adapter processes packets at line rate while applying security policies, performing encapsulation/decapsulation of overlay networks, and managing quality of service parameters. The RDMA capabilities enable direct memory access between systems without CPU involvement, significantly reducing latency for storage and clustering applications.
Implementation Environments
- Enterprise data center server connectivity
- Cloud infrastructure and hyperconverged systems
- Network function virtualization (NFV) platforms
- Software-defined storage and hypervisor environments
- High-performance computing clusters
- Big data analytics and machine learning platforms
