FebSmart CX516A is a PCIE GEN 4.0 X16 interface to 2X 100GbE optical ports intelligent RDMA enabled converged network adapter for Web 2.0, Cloud, Storage and Telcom Platforms. PCIE GEN 4.0 standard, 16GT/s per LANE. PCIE X16 Interface, provide 256Gb/s bandwidth, ensure 2X QSFP28 optical ports achieve 100Gb/s concurrently. Powered by Mellanox ConnectX-5 EX MT28808A0 2X QSFP28 100Gb/s Ethernet Controller, bring latest RDMA, SR-IOV, RoCE V2, Network Overlay, Open vSwitch offloads, Multi-Host, Socket Direct technology into Data Centers. Hardware-based RDMA engine, bypassing CPU and kernel, enabling direct memory access with sub‑microsecond latency and up to 200Gbps bandwidth under lossless RDMA over Converged Ethernet (RoCE V2) Protocols.I/O Virtualization SR-IOV technology, by providing dedicated adapter resources, guaranteed isolation and protection for virtual machines within the server. Supports up to 512 virtual and 16 physical functions. Open vSwitch offloads enabled, will drive extremely high packet rates and throughput with reduced CPU resource consumption, boosting data center infrastructure efficiency. Multi-Host technology, allows multiple hosts to be connected into a single adapter by separating the PCIE lane into multiple and independent interfaces. Socket-Direct, configurations that enable servers without x16 PCIE slots to split the card 16-LANE PCIE bus into two 8-LANE buses on dedicated cards connected by a harness. Comply with Open Fabrics Enterprise Distribution (OFED) and Open Fabrics Windows Distribution (WinOF-2). Supports Passive or active 25GbE SFP28 AOC, DAC cables, and 25GbE SFP28 transceivers with optical cables.
