The HPE 817709-B21 is specified as an Ethernet 10/25Gb adapter, meaning it is designed to operate at either 10Gb or 25Gb Ethernet link speeds. This dual-speed capability enables use in environments that currently run at 10Gb but may plan to move to 25Gb, allowing a single adapter type to be deployed across different performance tiers.
This adapter is defined as a 2-port model, providing two Ethernet interfaces on a single card. The dual-port configuration allows a server to connect to separate network segments, implement redundant paths, or support logical traffic separation according to data center design requirements.
The adapter is described as an SFP28-based Ethernet adapter. This means its network interfaces rely on SFP28 slots that accept compatible SFP28 transceivers or cabling. This specification guides the selection of optical modules or direct attach copper cables used to connect the adapter to switches or other network equipment.
The adapter is identified with the FLR designation, indicating it is built in an FLR form factor suited to FlexibleLOM-style integration. This impacts physical compatibility with HPE server platforms, so verifying support for FLR adapters in the target server model is an important step during planning and procurement.
Yes, this product is categorized at the enterprise level and is described as an HPE Ethernet 10/25Gb 2-port 631FLR-SFP28 adapter. Its support for 10/25Gb Ethernet speeds, dual-port configuration, and SFP28 FLR interface makes it appropriate for enterprise deployments that require standardized, high-speed network connectivity across multiple servers.
