Detailed Specifications
HPE P084 813889-B21 Synergy 4610C 10/25 Gb Ethernet Adapter
Overview
The HPE 813889-B21 is a network adapter providing two ports that operate at either 10 Gb/s or 25 Gb/s, intended for use in HPE Synergy compute modules. It supports full-line-rate dual-port connectivity and is designed for virtualised servers, high-performance compute nodes or storage-heavy workloads where high-speed uplinks are needed today and future-proofing for 25 Gb is required. The adapter installs in a mezzanine slot in the server, freeing standard PCIe slots for other functions, and supports advanced offload features such as SR-IOV, large virtual machine queues and tunnel/overlay handling. It is ideal for environments migrating from 10 Gb to 25 Gb Ethernet, enabling the same adapter to be reused without hardware replacement when infrastructure upgrades. Because it is compact and efficient, it suits dense rack deployments, converged infrastructure or high-bandwidth blade-style servers.
