MCX516A-CCAT ConnectX-5 EN Adapter Card 100GbE

MCX516A-CCAT ConnectX-5 EN Adapter Card 100GbE Dual-Port QSFP28 PCIe 3.0 x16 Tall Bracket ROHS R6


ConnectX-5 Ethernet network interface cards provide high performance and flexible solutions with up to two ports 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.

ConnectX-5 adapter cards are available for PCIe Gen 3.0 and Gen 4.0 servers and provide support for 1, 10, 25, 40, 50 and 100 GbE speeds in stand-up PCIe cards, OCP 2.0, and OCP 3.0 form factors. ConnectX-5 cards also offer advanced Multi-Host and Socket Direct technologies.
