ConnectX®-5 EN Single/Dual-Port Adapter Supporting 100Gb/s Ethernet

Intelligent ConnectX-5 EN adapter cards introduce new acceleration engines for maximizing High Performance, Web 2.0, Cloud, Data Analytics and Storage platforms.

ConnectX-5 supports two ports of 100Gb/s Ethernet connectivity, sub-700 nanosecond latency, and very high message rate, plus PCIe switch and NVMe over Fabric offloads, providing the highest performance and most flexible solution for the most demanding applications and markets.

ConnectX-5 Accelerated Switching and Packet Processing (ASAP2™) technology enhances offloading of virtual switches and virtual routers, for example, Open V-Switch (OVS), which results in significantly higher data transfer performance without overloading the CPU. Together with native RoCE and DPDK (Data Plane Development Kit) support, ConnectX-5 dramatically improves Cloud and NFV platform efficiency.
