Product Description
The NVIDIA Mellanox ConnectX-4 Lx EN MCX4111A-ACUT is a single-port 25 Gigabit Ethernet adapter that combines the full ConnectX-4 Lx offload feature set — QoS, CPU offloads, jumbo frames, storage acceleration, SR-IOV, NC-SI, LLDP and QCN — with UEFI, PXE and Secure Boot support for secure, manageable enterprise and OEM deployments. Built around the same MT27712A0-FDCF-AE controller as the MCX4111A-ACAT, it adds a pre-boot firmware stack that supports UEFI-based configuration, PXE network boot for diskless provisioning, and UEFI Secure Boot to validate firmware integrity against unauthorized code during the boot chain. Combined with RoCE v2 hardware-accelerated RDMA and SR-IOV virtualization, this SKU is well suited for security-conscious enterprise, government and OEM server deployments that require both high-bandwidth 25GbE networking and a trusted boot process.
