Description

Dual-port 10/25GbE SFP28 FLR adapter for high-throughput, low-latency server networking. Backward-compatible with 10Gb SFP+ optics and DACs, it enables an easy path to 25GbE while preserving existing 10Gb links. Ideal for virtualization and overlay networks with advanced offloads.

Features

- Flexible 10/25GbE upgrade path with 10Gb fallback
- Dual-port density for redundancy or multi-network segregation
- Advanced overlay and virtualization offloads to free CPU cycles
- SFP28 interface supports a wide range of optics and DAC/AOC cabling

FAQs

Q: Is this card compatible with 10Gb SFP+ optics and DACs?
A: Yes. Each SFP28 port is backward-compatible with SFP+ at 10Gb.

Q: Are transceivers or cables included?
A: No. SFP28/SFP+ optics and DAC/AOC cables are sold separately.

Q: Does it support SR-IOV for virtualization?
A: Yes, SR-IOV is supported on the BCM57414 controller.

Q: Which servers does the FLR form factor fit?
A: FLR adapters are designed for supported HPE servers with compatible slots; check your server’s QuickSpecs for FLR support.

Q: What link distance can I expect?
A: Distance depends on the selected transceiver or DAC/AOC cable. Refer to the optic or cable datasheet for reach.
