CX516A Dual 100Gb/s QSFP28 Ports Intelligent RDMA Ethernet Adapter for Web 2.0, Cloud and Storage Servers, Mellanox ConnectX-5 EX MT28808A0 Ethernet Controller, 2X 100GbE PCIE Gen 4.0 x16 NIC Card

CX516A is a PCIE Gen 4.0 x16 to dual 100GbE QSFP28 fiber ports intelligent RDMA Ethernet adapter. Operating at the PCIE Gen 4.0 standard with a PCIE x16 interface, it delivers a total bandwidth of 256Gb/s, ensuring both QSFP28 fiber ports achieve 100GbE network connectivity simultaneously. Based on the Mellanox ConnectX-5 EX MT28808A0 converged Ethernet controller, it provides dual 100GbE network connections with advanced application offload capabilities for Web 2.0, cloud, storage and telco servers.
ATTENTION: The Linkstek CX516A serves as a drop-in alternative to the MCX516A-CDAT for server applications.

Based on the Mellanox ConnectX-5 EX MT28808A0 converged Ethernet controller, it provides dual 100GbE network connections with advanced application offload capabilities for Web 2.0, cloud, storage and telco servers. It supports I/O virtualization with SR-IOV technology, providing dedicated adapter resources and guaranteed isolation and protection for virtual machines (VMs) within the server. It also supports Network Function Virtualization, allowing a VM to act as a virtual appliance. Full data path operation offloading, hairpin hardware capabilities and service chaining enable data to be processed by the virtual appliance with minimal CPU utilization. It supports overlay networks including VXLAN, NVGRE, MPLS, GENEVE and NSH. In addition, it supports RDMA over Converged Ethernet (RoCE), delivering efficient low-latency and high-performance RDMA services that greatly enhance storage application performance.
