HPE P42041-B21 10/25GbE SFP28 OCP3 Network Adapter
Overview
The HPE P42041-B21 is a high-performance Ethernet network adapter designed for HPE Gen10 Plus and Gen11 server platforms. This adapter provides dual-port 10/25GbE connectivity, addressing the demand for increased bandwidth and lower latency in modern data centers. It is specifically engineered for environments requiring efficient, scalable networking for hybrid cloud services, data-intensive applications, and video streaming workloads. The OCP 3.0 mezzanine form factor allows for flexible and dense integration without consuming a standard PCIe slot. At its core, this adapter leverages advanced I/O offload technologies, including Remote Direct Memory Access (RDMA), to reduce CPU utilization and improve overall system efficiency. By offloading network traffic processing, server processors are freed to focus on application performance. This capability is critical for virtualization, cloud computing, and storage applications where maximizing host resources is paramount for operational success and achieving higher virtual machine density. Designed for seamless integration within HPE server ecosystems, the P42041-B21 fits into the dedicated Open Compute Project (OCP) 3.0 slot, ensuring a clean and tool-less installation. This plug-in card is ideal for enterprise data centers and service providers looking to upgrade their network infrastructure. Its support for features like Wake on LAN (WOL), PXE boot, and advanced virtualization support (SR-IOV, VXLAN, NVGRE) simplifies deployment and enhances management across large-scale server fleets.
