HPE 777430-B21 Synergy 3820C 10/20 Gb Converged Network Adapter
Overview
The HPE 777430-B21 is a dual-port converged network adapter designed for the Synergy platform, supporting both 10 Gb and 20 Gb Ethernet connectivity and capable of consolidating LAN and storage I/O into a single link. It reduces I/O complexity by combining network and storage traffic, using a PCIe or mezzanine interface in server environments. This adapter is intended for composable infrastructure, dense rack servers and blade systems where high-bandwidth, low-latency connectivity is needed. It integrates with HPE server management and supports fabric-level provisioning and monitoring.
Key Features
Two ports supporting 10 Gb/20 Gb Ethernet speeds for high throughput.
Converged LAN and storage traffic support (Flex-20 technology) to reduce hardware count.
Mezzanine form-factor optimized for HPE Synergy compute modules.
PCI Express Gen3 host interface ensures full bandwidth back to the server.
Low power consumption (~12 W maximum) suited for high-density environments.
