HPE 876447-001 Synergy 4820C 10/20/25Gb Converged Network Adapter
Overview
The HPE 876447-001 is a mezzanine converged network adapter (CNA) built for HPE Synergy compute modules, supporting two ports at 10, 20, or 25 Gb/s. It unifies Ethernet and storage (FCoE or iSCSI) over a single connection, reducing cabling complexity. The adapter supports RDMA over Converged Ethernet (RoCEv2) and SR-IOV for efficient virtualization and low-latency data transfer. It is designed for high-performance, composable infrastructure in data centers and cloud environments.
