HPE QL41132HLCU-HE 10Gb 2-Port SFP+ PCIe Network Adapter
Overview
The HPE QL41132HLCU-HE is a high-performance 10 Gigabit Ethernet network adapter, engineered to optimize server efficiency and network throughput in demanding data center and enterprise environments. This dual-port SFP+ adapter addresses the critical need for increased bandwidth and reduced latency, offloading significant I/O processing from the host CPU. By freeing up valuable processor resources, it allows servers to handle more virtual machines (VMs) and complex application workloads, directly translating into improved operational efficiency and a lower total cost of ownership. Designed for seamless integration into HPE ProLiant and Apollo servers, this adapter leverages a PCI Express 3.0 x8 host interface for robust data handling. Its advanced capabilities support key virtualization technologies such as Single Root I/O Virtualization (SR-IOV), which dramatically increases VM density per server without sacrificing performance. Furthermore, with support for Remote Direct Memory Access (RDMA) protocols like RoCE and iWARP, the adapter accelerates data transfers and enhances application responsiveness, particularly in storage and high-performance computing scenarios. Deployment of the HPE QL41132HLCU-HE network adapter is typically within server chassis as a plug-in card, facilitating high-speed connectivity to network infrastructure via SFP+ transceivers. Its feature set extends to tunnel offloads for VXLAN, NVGRE, and GENEVE, ensuring efficient operation in modern overlay networking architectures. Management is simplified through compatibility with standard operating systems including various Microsoft Windows Server and VMware ESXi versions, enabling administrators to integrate and monitor the adapter within existing IT management frameworks.
