HPE QL41222HLCU-HP 10/25GbE 2P SFP28 Network Adapter
Overview
The HPE QL41222HLCU-HP is a high-performance, dual-port 10/25GbE SFP28 network adapter designed for HPE ProLiant Gen10 Plus servers. This Intelligent Ethernet adapter addresses the increasing bandwidth and security demands of modern data centers, hybrid cloud environments, and latency-sensitive applications. It is engineered to eliminate I/O bottlenecks and enhance server efficiency by offloading network traffic processing from the CPU. A key feature of this adapter is its Universal RDMA capability, which provides concurrent support for RoCE, RoCEv2, and iWARP protocols. This flexibility accelerates workloads such as Microsoft Storage Spaces Direct (S2D), NVMe over Fabrics (NVMe-oF), and other hyper-converged infrastructure deployments. By enabling direct memory access, it significantly reduces latency and boosts throughput for storage and cluster communications. Designed with a PCIe 3.0 x8 host interface, the adapter fits seamlessly into standard server slots. It supports advanced stateless offloads for tunneling protocols like VXLAN, NVGRE, and GENEVE, which optimizes performance in virtualized environments by preserving CPU cycles for application processing. Management is streamlined through HPE’s standard toolsets, ensuring consistent integration and control within the data center ecosystem.
