HPE Ethernet 10/25Gb 2-port 640FLR-SFP28 Internal

FlexibleLOM form-factor network adapter with two dual 10/25Gbe SFP28 ports supporting up to 50 Gb/s bi-directional per port pair and up to 100 Gb/s aggregate bi-directional theoretical bandwidth. The adapter is designed for systems with a FlexibleLOM slot and requires one x8 PCIe Gen3 slot for installation when used via PCIe.

Advantages

The FlexibleLOM form-factor provides a compact, server-integrated interface that frees standard PCIe slots. Dual 10/25Gbe SFP28 ports enable high-density, multi-rate connectivity and support 25G and 10G optical modules. The design offers high theoretical aggregate throughput while maintaining compatibility with systems that provide a FlexibleLOM or an x8 PCIe Gen3 slot.

Key specifications

• Form factor: FlexibleLOM
• Ports: Two dual 10/25Gbe SFP28 ports
• Per-pair bandwidth: Up to 50 Gb/s bi-directional
• Aggregate bandwidth: Up to 100 Gb/s bi-directional (theoretical)
• Host interface requirement: One x8 PCI Express (PCIe) Gen3 slot

How to use

Install the adapter into a compatible FlexibleLOM slot on the server. If a FlexibleLOM slot is not available, install the adapter into an available x8 PCIe Gen3 slot according to the server manufacturer’s installation instructions. Populate the SFP28 ports with appropriate 10G or 25G SFP28 modules and connect to the network. Configure link settings and drivers in the operating system as required for optimal performance.

Recommendations

Verify server compatibility with FlexibleLOM form-factor and confirm availability of an x8 PCIe Gen3 slot before purchase. Use certified SFP28 modules and appropriate cabling to achieve the specified rates, and ensure drivers and firmware are up to date.
