HPE QL41262HLCU-HP 25GbE 2-Port SFP28 Network Adapter
Overview
The HPE QL41262HLCU-HP is a high-performance dual-port 10/25GbE SFP28 Ethernet adapter designed for HPE ProLiant servers. It addresses the demand for increased network bandwidth and lower latency in modern data centers, cloud deployments, and high-performance computing environments. This adapter is engineered to alleviate I/O bottlenecks for storage and data-intensive applications. Powered by a Marvell FastLinQ 41000 series controller, the adapter features Universal RDMA, supporting both RoCE and iWARP protocols. This offloads host CPU resources by enabling direct memory access between servers, significantly accelerating workloads like Microsoft Storage Spaces Direct (S2D), NVMe over Fabrics, and virtual machine migrations. Key virtualization optimizations include SR-IOV and tunnel offloads for VXLAN, NVGRE, and GENEVE, which enhance VM density and performance in multi-tenant networks. As a PCIe 3.0 x8 plug-in card, this adapter integrates seamlessly into supported HPE server platforms. It offers backward compatibility with 10GbE infrastructure, providing a flexible and cost-effective upgrade path to 25GbE speeds. Management is handled through standard HPE utilities and native OS tools, while features like secure boot and authenticated firmware updates ensure a trusted and reliable network foundation.
