Detailed Specifications
HPE P01921-001 Synergy 4610C 10/25 Gb Ethernet Adapter
Overview
The HPE P01921-001 is a dual-port Ethernet network adapter designed for high-density server environments that require flexible uplink speeds. Each port supports both 10 Gb/s and 25 Gb/s link rates, enabling organisations to deploy current infrastructure at 10 Gb while retaining a seamless migration path to 25 Gb without replacing the adapter. Installed in HPE Synergy compute modules, this adapter leverages server mezzanine or dedicated network slots to deliver full-line-rate dual-port performance, reduce cabling complexity and preserve standard PCIe expansion slots. It is suitable for virtualised servers, converged-infrastructure nodes, storage-networking traffic and top-of-rack uplinks. With support for advanced offloads and modern network architectures, the adapter helps data-centre engineers deliver high-bandwidth connectivity and future-proof server uplink capability in a compact form-factor.
Key Features
Two ports capable of 10 Gb/s or 25 Gb/s each
