HPE P18671-B21 SmartNIC 10/25 Gb 2-Port SFP28 Adapter
Overview
The HPE P18671-B21 is a dual-port Smart Network Interface Card designed to provide future-proof server uplink connectivity for modern compute environments. Each port supports both 10 Gb/s and 25 Gb/s link speeds via SFP28 format, enabling deployment on current 10G infrastructures and seamless migration to 25G when required. The adapter installs into a server mezzanine or PCIe ×8 slot, conserving additional expansion slots and integrating cleanly with server I/O fabrics. With full line-rate performance on both ports and support for advanced offloads and virtualization features, it is suited for virtualised hosts, storage-traffic servers or dense rack deployments where dual high-speed uplinks and low‐latency traffic are key. The flexible media compatibility (optical or DAC) and server-certified form-factor make this adapter a solid choice for enterprises scaling their network bandwidth while maintaining efficiency and space optimisation.
