HP QL41232HLCU Network Adapter - PCIe 3.0 x8 10GbE/25GbE SFP28 Dual Port

The HP QL41232HLCU is a high-performance network adapter designed for enterprise data centers and demanding networking environments. Featuring dual SFP28 ports, it supports both 10 Gigabit Ethernet and 25 Gigabit Ethernet connectivity, providing flexible bandwidth options for server and storage applications. Built on the Broadcom BCM57412 controller, this PCI Express 3.0 x8 card delivers low-latency, high-throughput data transfer with advanced offload capabilities.

Advantages

This adapter enhances network efficiency through support for RDMA over Converged Ethernet (RoCE), SR-IOV, and NPAR, enabling virtualization and traffic optimization. Jumbo frames, TCP/IP offload, and tunnel offload (VXLAN, NVGRE, GENEVE) reduce CPU overhead and improve application performance. The included full-height and low-profile brackets ensure compatibility with various server chassis.

Suitable for

• Enterprise servers requiring high-speed 10/25GbE connectivity
• Virtualized environments leveraging SR-IOV and NPAR
• Storage networks utilizing iSCSI or FCoE
