HPE 813890-B21 Synergy 4610C 10/25 Gb Ethernet Adapter
Overview
The HPE 813890-B21 is a high-speed network adapter built for HPE Synergy platforms, offering two ports that support both 10 Gb/s and 25 Gb/s Ethernet connectivity. With this adapter, deployment teams can address current 10 Gb traffic demands and scale seamlessly to 25 Gb as the network evolves, all without changing server infrastructure. It installs in a PCI Express 3.0 ×8 mezzanine slot within Synergy compute modules, preserving spare PCIe slots for other uses. The adapter’s advanced offload capabilities enable virtualised workloads, converged networking and storage traffic consolidation with minimal CPU overhead. It is well suited for cloud, telco or enterprise data-centre nodes where bandwidth, flexibility and future-readiness matter.
