Mellanox controller: The 25g dual-port SFP+ network card is based on the Mellanox ConnectX-4 controller, which provide the highest performing and most flexible interconnect solution. PCIe v3.0 X8. Technical Support: iPXE、DPDK、iSCSI、Jumbo Frames、FCoE、RDMA（RoCE v1, RoCE V2）. It has a 1, 10, 25 GIGABit connection to meet the virtualization application of network facilities.It provides better server utilization for the data center while reducing costs, cabling complexity, and so on. It can effectively solve the problem that vm traffic is transmitted through encapsulated logical tunnels (such as NVGRE and VXLAN). It solves the network scalability and load problem on the host CPU. Enjoy 24/7 customer service, 30-day free returns, 1-year free warranty, and lifetime technical support for your peace of mind. HSES1026PF-2SFP28 is a PCIe v3.0 x8 dual-port 25G ethernet network adapter developed by Hengshi (Shenzhen) Electronics Co., Ltd. based on mellanox ConnectX-4 chip. It has 1/10/25G connection for virtualization applications of network facilities, local hardware support based on Ethernet stateless uninstallation engine, direct connection technology, etc. The SR-IOV technology of HSES1026PF-2SFP28 provides dedicated adapter resources for virtual machines in the server to meet the guarantee of isolation and protection. At the same time, I/O virtualization provides better server utilization in the data center while reducing costs and cabling complexity. Allow more virtual machines to run on the same hardware to meet more user needs. HSES1026PF-2SFP28 adopts NVGRE, VXLAN and GENEVE hardware uninstallation engine to effectively solve the problem of virtual machine traffic transmission through encapsulation format (such as NVGRE and VXLAN) logical tunnel. It solves the network scalability and the load on the host CPU. These offloading engines encapsulate and unencapsulate coverage protocol headers, enabling traditional offloading to be performed on encapsulated traffic from these and other tunneling protocols (Geneva, MPLS, QinQ, etc.). HSES1026PF-2SFP28 provides a very economical and flexible Ethernet adapter solution for Web 2.0, cloud, data analytics, database and
