HPE 879666-001 Ethernet 10/25gb 2-port Network Adapter

HPE 879666‑001 661SFP28 Dual‑Port 10/25 GbE Adapter

Overview

The HPE 879666‑001 is a server‑class network interface adapter designed for deployment in data‑centre and enterprise server environments where high‑speed Ethernet connectivity is required. It provides two SFP28 ports capable of 10 Gbps or 25 Gbps operation, enabling uplink or server‑access links in racks supporting top‑of‑rack or spine‑leaf fabrics. The adapter plugs into a PCI Express slot in compatible HPE ProLiant servers and uses the system’s existing power and cooling architecture. Ideal for applications such as virtualised server clusters, high‑performance compute nodes or storage‑front‑end servers, the 661SFP28 adapter helps network engineers upgrade to 25 GbE infrastructure without replacing the host server. It fits into standard rack servers and integrates with HPE server management and driver ecosystems for unified lifecycle operations.
