    Up to 100Gb/s Ethernet Adapter Cards

    ConnectX-5 Ethernet network interface cards provide high performance and flexible solutions with up to one port of 100GbE connectivity, 750ns latency, up to 200 million messages per second (Mpps), and a record-setting 197Mpps when running an open-source Data Path Development Kit (DPDK) PCIe (Gen 4.0). For storage workloads, ConnectX-5 delivers a range of innovative accelerations, such as Signature Handover (T10-DIF) in hardware, an embedded PCIe Switch, and NVMe over Fabric target offloads. ConnectX-5 adapter cards also bring advanced Open vSwitch offloads to telecommunications and cloud data centers to drive extremely high packet rates and throughput with reduced CPU resource consumption, thus boosting data center infrastructure efficiency.
