Frequently Asked Questions

What transceivers are compatible with the 817716-001 SFP28 ports?

The 817716-001 supports SFP28 (25GbE) and SFP+ (10GbE) transceivers, including HPE-branded DAC cables, AOCs, and optical SFP28 modules. Third-party transceiver compatibility varies — HPE-branded transceivers are recommended for full support.

Is 817716-001 compatible with 10GbE switches?

Yes — the SFP28 ports are backward compatible with 10GbE SFP+ infrastructure, allowing connection to existing 10GbE top-of-rack switches while enabling a future upgrade to 25GbE.

Does 817716-001 support SR-IOV for virtualization?

SR-IOV support depends on the firmware version and host OS driver. Consult HPE QuickSpecs and the server's virtualization platform documentation for SR-IOV configuration details.
