Detailed Specifications
HPE 817709-B21 - Ethernet 10/25Gb 2-Port 631FLR-SFP28 Adapter
Overview :
The HPE 817709-B21 is a dual-port network adapter designed for enterprise server environments where upgrading from 10 GbE to 25 GbE is required. It supports either 10 Gb/s or 25 Gb/s speeds per port via SFP+ (10G) or SFP28 (25G) modules, enabling higher throughput and reduced latency in virtualised or I/O-intensive workloads. This adapter fits into the FlexibleLOM (FLR) slot or PCIe Gen3 x8 form-factor and is suitable for data centre, edge, or cloud-scale server deployments. It also integrates into the HPE server ecosystem and is compatible with HPE ProLiant platforms, allowing unified management under HPE's server management tooling.
Key Features :
Supports dual ports at 10 Gb/s or 25 Gb/s each
SFP+ or SFP28 for optical or copper connectivity
PCIe Gen3 x8 interface for flexible server slots
Firewall-level firmware protection and Root-of-Trust architecture
Offloads network I/O with SR-IOV and RoCE support
