    • Product description Compatible with: MCX4121A-ACAT; Controller: NVIDIA/Mellanox ConnectX-4 Lx (device family ConnectX4LX, PCI device mt4117). Ports: 2× SFP28 10/25GbE (accepts 25G SFP28 optics/DAC/AOC; supports 10GbE with SFP+ modules; limited 1GbE SFP support as per module and firmware). . Interface: PCIe 3.0 x8; Brackets: Full-Height & Low-Profile included; Boot: PXE/iSCSI (UEFI/Legacy as supported). . Features: SR-IOV virtualization, RDMA over Converged Ethernet (RoCE v2), stateless offloads (TSO/LRO/Checksum), overlay offloads (VXLAN/NVGRE/Geneve), RSS, low latency. . 2× SFP28 (10/25G), PCIe 3.0 x8 PERFECT FOR: VMware ESXi/Proxmox/Hyper-V/KVM, Kubernetes/containers, NVMe-oF/iSER storage, TrueNAS/Ceph, cloud & data-center servers needing high PPS and sub-µs latency. This dual-port SFP28 10/25GbE adapter is based on the NVIDIA/Mellanox ConnectX-4 Lx controller, delivering sub-microsecond latency, high message rate, and rich offloads for modern virtualization and storage. It fits PCIe 3.0 x8 slots and ships with both full-height and low-profile brackets to suit rack servers and compact cases. Hardware accelerations include SR-IOV VFs, RoCE v2 RDMA, VXLAN/NVGRE/Geneve overlay offload, and TSO/LRO/checksum, reducing CPU use and boosting throughput for ESXi/Proxmox/Hyper-V/KVM, Kubernetes nodes, and TrueNAS/Ceph backends. Ports are SFP28 cages: use SFP28 optics/DAC/AOC for 25GbE, SFP+ modules for 10GbE, and select 1GbE SFPs where supported by optics and firmware. This adapter i
