HPE P60339-B21 10/25GbE 2-Port SFP28 OCP3 Adapter
Overview
The HPE P60339-B21 is a high-speed, dual-port Ethernet network adapter designed for modern data centers requiring significant bandwidth and low latency. Engineered for HPE ProLiant Gen10 Plus and Gen11 servers, this adapter provides a direct and efficient network interface in the OCP 3.0 (Open Compute Project) mezzanine form factor. It is targeted at enterprise environments running demanding workloads, such as server virtualization, high-performance computing (HPC), and scalable cloud services, by alleviating I/O bottlenecks. This adapter leverages NVIDIA Mellanox ConnectX-6 Lx technology to deliver robust 10GbE and 25GbE connectivity. A key technical feature is its support for Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE), which allows for direct memory access between servers, bypassing the CPU. This significantly reduces latency and CPU overhead, resulting in faster application response times and improved server efficiency for data-intensive tasks. Designed for seamless integration, the P60339-B21 fits into the dedicated OCP 3.0 slot on compatible server motherboards, offering a tool-less, hot-pluggable installation. This mezzanine card approach saves a standard PCIe slot for other expansion needs. Management is integrated into HPE’s native server management platforms, like Integrated Lights-Out (iLO), allowing for streamlined configuration and monitoring within the existing infrastructure management framework.
