A: Yes. SFP28 ports accept SFP+ modules and operate at 10GbE with compatible optics or DAC/AOC.

Q: What PCIe slot is required?
A: Use a PCIe 3.0 x8 (or x16) slot to ensure full 25GbE performance.

Q: Is SR-IOV supported?
A: Yes, SR-IOV is supported for hardware-assisted virtualization.

Q: Which cables and optics are supported?
A: MSA-compliant SFP28 25G optics and DAC/AOC are supported; SFP+ modules/cables enable 10G operation.

Q: Does it support jumbo frames?
A: Yes, up to 9K MTU.
